Generator Tracking & Monitoring: Runtime Hours, Fuel, Mains Failure, and Theft Protection for Every Genset
A generator is a stationary asset with no odometer, no route, and no driver, yet it is frequently the highest-value machine on a site per hour of operation. Kendaall’s generator monitoring platform instruments diesel and petrol gensets — from 5kVA portable units to 2,000kVA plant-room installations — with five connected data layers: independent runtime hour metering, ±1-litre fuel monitoring, unauthorised start alerts, automatic transfer switch (ATS) mains-failure and changeover monitoring, and GPS theft protection. The result is a genset that reports its own hours, its own fuel consumption, and its own response to a blackout, rather than relying on a caretaker’s account of what happened.

Five Questions a Genset Cannot Answer on Its Own
A diesel or petrol generator, commonly called a genset, is an internal combustion engine coupled to an alternator that converts fuel into electrical power on demand. Unlike a vehicle, a genset has no odometer, no speedometer, and no built-in record of its own activity beyond a mechanical hour meter on the control panel — a component that can be reset, bypassed, or simply misread. Everything a vehicle tracking system measures — distance travelled, route taken, idle time — has no natural equivalent on a stationary engine. What a genset generates instead is a small set of high-value operational questions, and Kendaall’s platform is structured around answering each one with wired instrumentation rather than a caretaker’s report: Did the generator run, and for how long? What fuel did it consume while running? Who authorised the start? Did it respond correctly when mains power failed? Is it still positioned where it is supposed to be?
These five questions are related to one another, and a monitoring platform has to model the relationships correctly to be useful rather than simply collecting five unconnected numbers. Runtime hours by themselves do not distinguish an authorised job from an unauthorised one — that distinction only exists once runtime is cross-referenced against a start-event schedule. Fuel consumption by itself is only informative when set against runtime hours, because litres consumed per hour of runtime is the figure that exposes theft; a falling fuel level with no corresponding engine hours is either a leak or a siphon, not normal burn. A mains-failure event only becomes a success or a failure once it is paired with the generator’s start response, measured in seconds from grid loss to load pickup. And a generator’s position only carries meaning against its expected, geofenced location, because a stationary asset has no baseline “normal” movement — any movement at all is the signal that something changed. Kendaall’s platform links runtime, fuel, start events, mains events, and GPS position as records about a single machine, not as five independent feeds.
Runtime, fuel, start events, and mains-failure data from a single genset, read as one connected record. (Replace with your genset installation photo.)
Each of the five questions maps to a specific piece of hardware and a specific data layer. A monitoring unit wires into the genset’s control and charging circuits to capture true crank-on runtime, independent of the control panel’s own hour meter and unaffected by any claim that the meter has failed. A calibrated capacitive fuel level sensor, fitted inside the day tank and, where relevant, the bulk storage tank, logs every litre in and out continuously, at roughly ±1-litre resolution — fine enough to register a siphon hose removing diesel rather than an engine burning it under load. Start events report the instant the genset cranks, matched against a defined working-hours schedule that flags a run nobody authorised. Mains-sense wiring, connected at the automatic transfer switch (ATS), records every grid failure alongside whether — and how quickly — the genset picked up the load, converting an assumption about backup power into a dated, timestamped record. GPS positioning stays fitted even on generators expected to remain permanently static, because the day a static asset moves without authorisation is the day its location becomes the most important figure on the account; an unscheduled move is treated with the same urgency Kendaall’s stolen vehicle recovery service applies to a car.
Generator monitoring intersects with a wider set of standards and hardware categories that shape how the platform is engineered. The automatic transfer switch (ATS) is the component that physically routes a building’s electrical load between the mains grid connection and the generator supply, and it is the exact point at which Kendaall’s mains-sense wiring listens for a changeover event. Internationally, generating sets built for standby and prime power duty are specified against the ISO 8528 family of standards for reciprocating internal combustion engine driven alternating current generating sets, and critical facilities such as hospitals frequently design their emergency and standby power systems around the principles set out in NFPA 110, the U.S. standard for emergency and standby power systems that many institutional specifications across East Africa continue to reference. Kendaall’s platform does not replace this engineering; it verifies, in operational data collected from the field, whether a system built to these standards is behaving the way it was designed to on the day it is actually tested.
The distinction between engineering specification and operational verification is central to why generator monitoring exists as a separate discipline from generator installation. A genset can be correctly specified against ISO 8528 duty ratings, correctly installed by a certified electrician, and still fail on the one day it is needed, because mechanical specification answers “can this system work” while monitoring data answers the separate question “did this system work, on this occasion, at this site.” A business that has only ever addressed the first question is running its backup power on an assumption rather than a record. Monitoring converts that assumption into evidence — the same shift that turns a generator from a piece of standby equipment sitting in a shed into an asset with a reportable, auditable performance history, comparable to how a fleet of vehicles is reported on rather than simply trusted to exist and function.
Fuel and runtime hours concentrate the majority of a genset’s operating cost, which is why these two data layers carry the heaviest economic weight on the platform. Diesel consumption scales with engine load and set size: a 100kVA standby set commonly burns in the order of 20 litres per hour under substantial load, based on typical manufacturer fuel-consumption tables, and a telecom or borehole site running daily backup cycles can move hundreds of thousands of shillings of diesel through a single tank across a year with no independent witness to that consumption. Fuel loss through siphoning, short deliveries, and unverified “top-ups” behaves the same way it does on the heavy machinery side of a mixed fleet — commonly cited in the 10–20% range of total throughput, invisible until it is measured directly against a sensor rather than a delivery note. For generator hire companies, hours are revenue: a disputed meter reading is disputed income, and an independent runtime feed converts hire billing from a negotiation into a documented statement of fact. Kendaall’s platform scales from a single standby genset behind a Nairobi office to distributed estates spanning telecom towers, borehole pumps, and event fleets across Kenya, Uganda, and Tanzania, visible in the same account as a business’s vehicles and heavy machinery through fleet management.
Six Failure Modes on Unmonitored Gensets, and the Data Layer That Exposes Each
Each failure mode below traces to the same root cause: a generator produces very little information about itself, so the resulting gap is filled by whoever stands closest to the machine — a caretaker, a hired-out client, a night guard, or a fuel attendant. Kendaall closes that gap with a wired, timestamped record before it turns into a loss on the books.
Fuel Theft: The Tank That Empties Faster Than It Burns
Genset fuel theft is difficult to detect on an unmonitored site because the tank often sits outdoors or in a semi-accessible plant room, refills are logged on paper if at all, and consumption is estimated against a delivery note nobody cross-checks. A calibrated fuel level sensor removes the estimate: every litre is logged continuously, every delivery is verified in litres against the supplier’s invoice at the moment it happens, and any abnormal drop while the engine is stationary — the signature of a siphon hose rather than combustion under load — triggers a real-time alarm with a timestamp. On distributed estates such as telecom towers or borehole networks, fuel curves across every site sit on one screen, and the site whose curve diverges from its neighbours is, in most cases, the site with the problem. Full capability detail is on the fuel monitoring service page.
Hire Billing Disputes: A Meter the Client Controls
Generator hire companies typically bill by the hour against a control-panel meter that physically sits on the client’s site, is read by the client’s own staff, and is photographed and reported back when convenient. This arrangement places the party being billed in control of the figure the invoice is based on — a structural conflict unrelated to anyone’s honesty and entirely a function of incentives. Kendaall’s independent runtime feed streams true crank-on hours to the hire company’s dashboard regardless of whose compound the set sits in, building per-contract hour ledgers, automated over-run charges, and invoices backed by telemetry instead of a self-reported reading. It applies the same dispute-ending logic Kendaall’s car hire clients already use for kilometres, applied here to engine hours.
Unauthorised Use: Runs Nobody Scheduled
Gensets are frequently used without ever leaving the compound. A night run powers a neighbour’s welding job; a caretaker charges a side business off a socket in the plant room; an adjacent event quietly draws power from a “spare” set for an evening. None of this registers as theft in the conventional sense, since the machine never moves, but it consumes diesel, engine hours, and service life for someone else’s benefit. Start alerts matched against working-hours rules flag every unscheduled run the instant it cranks, and the runtime ledger attributes each hour to either a schedule or a flagged exception. Most clients discover a genset’s unauthorised use within the first two weeks of monitoring going live.
Failed Changeover: The Blackout Test With No Rehearsal
A standby generator has one job, performed on the single worst day possible, with no opportunity to rehearse. Hospitals, cold rooms, data closets, and hatcheries routinely discover a failed changeover only after the fact — spoiled vaccines, a downed server rack, dead livestock. Mains-sense monitoring at the automatic transfer switch records every mains failure alongside whether the genset actually started, how long pickup took, and exactly when mains power was restored, turning an assumption that “the generator works” into a per-blackout record that can be checked at any time. A failed auto-start sequence at two in the morning triggers an alert immediately, so the response happens before a freezer temperature climbs, not after.
Service by Calendar on a Machine That Ages by the Hour
Generators are typically serviced on a fixed calendar interval — quarterly, for example — while mechanical wear accumulates by the hour, not the month. A set that ran 400 hours through a difficult grid season is overdue for service before the second month of that quarter, while an idle standby set wastes money on oil changes it never needed. True runtime metering drives service scheduling by actual hours run, with threshold alerts and per-set service histories that protect manufacturer warranties and resale value — the same predictive maintenance discipline already applied to Kendaall’s vehicle fleets, applied here to assets whose failure can take an entire site down with them.
Portable Generator Theft: The Set That Walked Off Site
Small and towable gensets rank among the most-stolen categories of equipment on construction and event sites in Kenya — high resale value, demand across trades, and easy removal in a single pickup load overnight. The monitoring unit’s GPS layer arms the moment a set is expected to remain static: movement without a logged transfer order triggers an instant alert, live pursuit tracking, and recovery-team coordination, backed by an internal battery that keeps transmitting even if a thief cuts the primary power supply. For hire fleets, every set’s location becomes real-time inventory — which client site it is on, since when, and whether it is actually still there.
Standby, Prime Power, Hire, Portable, and Distributed Estates Each Need a Different Configuration
Before specifying a monitoring configuration, it is necessary to identify the duty role a genset performs, because the role changes which of the five monitoring questions matters most. The generator industry generally sorts equipment into a small number of duty categories, each with a different relationship to runtime, fuel, and mains data.
Standby (Emergency Backup) Generators
A standby set exists to answer the mains-failure question. It sits idle for most of its operating life and is judged almost entirely on its performance during the limited hours per year the grid actually fails. For this category, mains-sense and changeover monitoring dominate the configuration, with fuel sensing added to guard against a tank running dry at the exact moment the genset is needed — a failure mode invisible until the one occasion it matters. Standby duty is one of the classifications referenced in ISO 8528, and hospitals in particular frequently align their standby power expectations with NFPA 110.
Prime Power Generators
A prime power set is the sole or primary electricity source for a site, common on remote construction projects, off-grid farms, and telecom installations without a stable grid connection. Here, runtime hours and fuel burn dominate the configuration, because the generator effectively functions as the site’s utility provider, and its cost-per-kWh needs to be understood the way any other major recurring operating cost would be.
Hire Fleet Generators
A hired-out genset is a revenue-generating asset that happens to sit on someone else’s property for weeks or months at a time. Runtime hours drive billing directly, GPS position drives inventory and recovery, and fuel data protects against consumption disputes at handover. All three modules typically apply together across hire stock.
Portable and Towable Generators
Small petrol or diesel units used on construction sites and at events are valued for mobility, which is precisely what makes them a theft target. For this category, GPS and geofencing dominate the configuration, with runtime and fuel data added mainly to support billing at events or hire jobs.
Distributed Backup Estates
Telecom towers, borehole pumps, and multi-branch retail or banking sites often run identical small-to-mid gensets across a wide geography. Here, the priority shifts to fleet-wide comparison: fuel curves, runtime patterns, and mains-failure rates benchmarked site against site, so the one location behaving differently from its peers surfaces automatically rather than requiring manual review.
This taxonomy is why Kendaall configures every installation to the set’s actual duty role rather than selling a single fixed package. A standby hospital generator and a hired-out 60kVA set on a construction site are both gensets in the general sense, but they raise almost entirely different questions for the monitoring platform, and the hardware and reporting configuration reflects that difference from the day of installation.
A genset’s duty classification can also change over its working life, and the monitoring configuration should change alongside it. A set purchased new as a hospital’s standby unit may, years later, be sold into a hire fleet once the institution upgrades to a larger installation; a portable unit bought for a single event may later take on regular prime-power duty on a small off-grid farm. Because Kendaall’s monitoring unit is fitted independently of the genset’s own control electronics, reconfiguring the platform to match a new duty — adding GPS theft protection when a set enters a hire fleet, or adding mains-sense wiring when a portable set becomes permanent backup — is a software and light-wiring change rather than a hardware replacement, supported through the same transfer support used whenever a set changes ownership or role.
Five Monitoring Modules, One per Question
Each module below corresponds directly to one of the five questions introduced earlier. They can be deployed individually or together, and most installations combine two or three depending on the genset’s role in the duty taxonomy above.
MODULE 01 · True Runtime Metering & Hire Billing
Crank-on to crank-off runtime is captured directly from the genset’s own circuits, independent of the control panel’s built-in hour meter, unaffected by a claim that the meter is faulty, and exportable per day, per site, and per contract. Hire companies receive per-contract hour ledgers with automated over-run calculation the moment a job exceeds its agreed hours; owner-operators get honest diesel budgeting and utilisation figures across an entire estate; and every other module on the platform depends on this feed, because fuel burn rate, service intervals, and cost-per-kWh are each expressed as a rate against runtime hours.
- Circuit-wired runtime capture, independent of the control-panel meter
- Per-contract hour ledgers and automated hire over-run billing
- Load-band logging (where supported) separating idle time from working runs
- Estate-wide utilisation views for multi-site operators
MODULE 02 · Fuel Monitoring: Tank, Delivery & Burn
A calibrated capacitive sensor logs the day tank — and, where fitted, the bulk storage tank — continuously at roughly ±1-litre resolution. The platform reads the resulting curve rather than a single reading: deliveries are verified in litres against supplier invoices at the moment they arrive, burn rate is benchmarked per set and flagged the instant it drifts from its own historical baseline (drift is as often an early engine-health signal as it is a theft signal), and any drop in fuel level while the engine is stationary triggers an instant siphoning alarm. Bowser-to-tank-to-burn reconciliation closes the loop that most site-level fuel theft depends on staying open.
- ±1-litre continuous monitoring, calibrated to each tank’s geometry
- Delivery verification: litres received versus litres invoiced
- Instant siphoning alarms with time and site identification
- Burn-rate benchmarking as an engine-health early warning signal
MODULE 03 · Start Governance & Security Alerts
Every crank event reports instantly and is tested against the genset’s defined operating schedule: authorised runs log silently in the background, while unscheduled starts alert the owner within seconds of ignition. Panel-door sensing, battery-disconnect alarms, and tamper detection guard the machine itself against interference, while working-hours rules turn the runtime ledger into a true attribution record — every logged hour belongs either to a schedule, a mains-failure response, or a flagged exception that someone has to account for.
- Instant start and stop alerts with schedule-based exception flagging
- Panel, battery, and wiring tamper alarms
- After-hours and weekend run reports per set and per site
- Escalation chains: caretaker, site manager, owner, response team
MODULE 04 · Mains-Failure & ATS Changeover Monitoring
Mains-sense wiring, connected at the site’s automatic transfer switch, records every grid failure alongside the genset’s actual response: start delay, successful load pickup, run duration, and return-to-mains — logged per blackout, per site, indefinitely. Standby owners get uptime assurance, plus an alert if the auto-start sequence fails at any hour; multi-site operators get a grid-reliability map of their own estate built from recorded events rather than assumptions; and facilities teams get the changeover audit trail that service-level agreements, insurers, and hospital boards routinely request after an incident involving critical power.
- Per-blackout event records: failure, start delay, pickup, restoration
- Failed-start alarms the moment the set should have run and did not
- Estate-wide outage and runtime mapping across sites
- Exportable uptime reports for SLAs, audits, and insurers
MODULE 05 · Position, Theft Protection & Portable Fleet Inventory
The GPS layer that stationary assets need precisely because they are assumed not to require one: geofenced home positions with instant movement alarms, live pursuit tracking with backup-battery transmission that survives a cut power supply, and a transit mode for authorised relocations so a legitimate move does not trip a false alarm. Hire fleets run this module as live inventory — every set’s site, tenure, and status visible on one map — and towable or trailer-mounted units pair naturally with the long-life magnetic asset trackers deployed across Kendaall’s asset tracking service more broadly.
- Home-position geofences with instant unauthorised-movement alarms
- Live recovery tracking with internal battery fallback
- Transit mode for approved deliveries and site transfers
- Hire-fleet inventory: which set, which site, since when

The Vocabulary of Generator Monitoring
Generator monitoring draws terms from three fields — power engineering, fleet telematics, and fuel management — and conversations often stall because a term carries a slightly different meaning in each. The definitions below describe how each term is used across Kendaall’s platform and this page.
Genset
Short for “generating set,” a genset is the combined unit of an engine and an alternator that convert fuel into electrical power. The word is used interchangeably with “generator” throughout the industry and this page, though strictly a generator is only the alternator half of the pairing, and the engine is the prime mover that drives it.
Runtime Hours
The cumulative time a genset’s engine has run, measured from crank-on to crank-off. Runtime hours are the basis for hire billing, hour-based service scheduling, and cost-per-kWh calculations, which is why an independent, circuit-wired measurement matters more for a generator than for almost any other class of equipment on a site.
Automatic Transfer Switch (ATS)
The switching device that detects a mains power failure and physically transfers a building’s electrical load from the grid connection to the generator, then transfers it back once mains power is restored and stable. Mains-sense monitoring listens at this switch to log the exact timing of every changeover event.
Mains Failure / Changeover Event
The record of a single blackout, from the moment grid power is lost through the generator’s start delay, successful (or failed) pickup of the load, the duration of the run, and the moment power reverts to mains. Each event is logged individually rather than as a running total, because the details of any one failure — particularly a failed start — matter more than an aggregate count of blackouts.
Fuel Burn Rate
Litres consumed per hour of runtime, typically benchmarked against a genset’s expected consumption at a given load. A burn rate that drifts upward without a corresponding increase in load is one of the clearest available signals of either fuel theft or a developing engine fault.
Load Band
A classification of how heavily a genset is loaded during a given run — idle, light, or full load — used to make fuel-burn benchmarking and cost-per-kWh figures more accurate, since an idling engine and a fully loaded one consume very different amounts of diesel per hour even though both count identically toward total runtime hours.
Geofence
A virtual boundary drawn around a genset’s expected, static location. Because a generator is not supposed to move at all in most deployments, its geofence is typically drawn tight around the home position, and any crossing of that boundary is treated as a high-priority alert rather than a routine notification.
Prime Power vs. Standby Duty
Two of the duty classifications referenced in international genset specification standards such as ISO 8528. Standby duty describes a generator that only runs during a mains failure; prime power duty describes a generator that is the primary, ongoing source of electricity for a site. The distinction affects both how the set is engineered and, in Kendaall’s platform, which monitoring modules matter most for that installation.
Day Tank and Bulk Storage Tank
The day tank is the smaller fuel reservoir mounted on or near the genset that feeds the engine directly, typically sized to hold enough diesel for a set number of hours of operation. The bulk storage tank, where fitted, is a larger reservoir that supplies the day tank, often via a transfer pump. Kendaall’s fuel sensors are calibrated to the geometry of whichever tank they are fitted to, and larger estates commonly monitor both.
Genset Controller
The electronic module that manages a generator’s start, stop, and protection functions, and in many installations also manages automatic transfer switch operation. Deep Sea Electronics and ComAp are two manufacturers whose controllers are common on gensets across East Africa; where one is already fitted, Kendaall’s monitoring unit can read its data as an additional layer rather than duplicating the same measurements with separate hardware.
Siphoning
The unauthorised removal of fuel from a tank, typically by hose, bucket, or pump, distinct from normal consumption through engine operation. A fuel level sensor identifies siphoning by detecting a drop in tank level that occurs while the engine is not running, since normal consumption only occurs during logged runtime.
Cost-Per-kWh
The effective cost of electricity generated by a genset, calculated from fuel consumed, runtime hours, and load band over a given period. Prime power sites use this figure the way a grid-connected business would use its utility bill, and it is only accurate once fuel and runtime data are both measured independently rather than estimated.
What Changes Once the Genset Reports Its Own Data
The clearest way to see the effect of instrumentation is to compare what a business can verify before monitoring against what the same business can verify in the first month after monitoring goes live. The pattern repeats across nearly every client, regardless of genset size or industry.
| Question | Before Monitoring | After Monitoring |
|---|---|---|
| How many hours has the genset run this month? | Control-panel meter reading, self-reported by site staff or client | Independent circuit-wired runtime feed, exportable per day and per contract |
| How much fuel was actually delivered? | Delivery note taken on trust; tank checked visually, if at all | Litres logged automatically at delivery and reconciled against the invoice |
| Did the generator start when mains power failed? | Assumed yes, unless a problem happened to be noticed | Timestamped record of the failure, start delay, and load pickup for every event |
| Was the genset used outside working hours? | Unknown, unless a fuel or hour discrepancy surfaced weeks later | Instant alert at the moment of an unscheduled start |
| Is the portable unit still on site? | Confirmed only by physically visiting the site | Continuous geofenced position with instant movement alarms |
| Is the service interval based on actual wear? | Fixed calendar interval, regardless of hours run | Threshold alerts triggered by true runtime hours |
Where Generator Monitoring Changes the Numbers: Fuel, Hours, Uptime, and Recovered Assets
Business owners evaluating a monitoring platform generally ask where the subscription cost is recovered. For generators specifically, the answer concentrates more tightly than it does for most equipment categories, because a large share of a genset’s total cost of ownership sits inside two of the five monitoring questions — fuel and hours — with uptime and asset recovery acting as less frequent but higher-stakes outcomes.
On the fuel side, the return is arithmetic. A business that has never measured its genset’s fuel consumption independently typically has no reliable baseline for normal burn rate, which means theft, short deliveries, and drift from a developing engine fault all hide inside the same unmeasured figure. Once a calibrated sensor establishes that baseline, any deviation becomes visible immediately instead of accumulating quietly over months. For a site burning meaningful diesel volume — a telecom tower running nightly backup cycles, a hospital standby set, a hire company’s fleet — the value of the first exposed discrepancy commonly exceeds several months of the monitoring subscription on its own.
On the hours side, the return depends on which party is paying whom. For a hire company, independent runtime data functions close to a direct multiplier on billing accuracy, because every hour previously lost to a disputed or under-reported meter reading becomes an hour actually invoiced. For an owner-operator, the same data instead protects against over-servicing and under-servicing in roughly equal measure — the quarterly oil change that was never needed, and the service interval quietly missed because the control-panel meter under-read the true hours.
Uptime and theft recovery sit at the far end of the same spectrum: lower in frequency, but often the single largest financial event a generator is ever involved in. A failed changeover at a hospital or cold-storage site can cost more in a single incident than years of monitoring fees, and a recovered portable genset after a theft attempt can represent the entire replacement value of the unit. These are the events a business hopes never to need the platform for, and the reason the platform is engineered to catch them regardless.
Businesses Whose Backup Power Depends on a Machine in a Shed
Generator Hire Companies
Independent hour meters on every hired set, live fleet inventory across client sites, telemetry-backed invoices that end billing disputes before they start, and theft protection on assets that earn revenue away from home base. Hour data feeds directly into service scheduling as well, protecting warranty and resale value across the whole rental stock rather than only the units currently on hire.
Telecom & Infrastructure Sites
Distributed genset estates carry high fuel-loss exposure, because each tower or cabinet site is visited infrequently and often relies on a local caretaker for fuel top-ups. Per-site fuel curves, delivery verification, runtime attribution, and outage mapping bring an entire backup power network onto one screen, with the outlier site surfacing on its own.
Hospitals & Institutions
Changeover assurance where failure is measured in more than money. Per-blackout response records, failed-start alarms, and the uptime audit trail that boards, insurers, and health regulators expect after any incident involving critical power, aligned with the emergency power principles set out in standards such as NFPA 110.
Construction Sites
Site gensets monitored on the same platform as the excavators and graders working beside them — fuel control, unauthorised-run alerts, and theft protection for equipment that is typically taken first by thieves because it is smaller and easier to move than the plant surrounding it.
Events & Entertainment
High-value portable sets deployed to fields and venues for days at a time: live location tracking, run-hour billing per event, fuel reconciliation between load-in and load-out, and movement alarms if the show has ended but the genset has not returned home on schedule.
Farms & Borehole Operators
Pump gensets running unattended cycles far from the farmhouse: runtime verification, fuel curves that expose the unsupervised diesel economy that tends to build up around remote sites, and start alerts, alongside the tractors on the agriculture platform already visible in the same account.
One Monitoring Unit, Configured to the Genset — From 5kVA Portable to 2,000kVA Plant Room
Installation wires the monitoring unit to the genset’s battery, control, and charging circuits, fits and calibrates the tank sensor, and adds mains-sense connection to the automatic transfer switch where changeover monitoring has been specified. A typical single-set installation takes 60–120 minutes, performed at the client’s site by certified technicians, with multi-site estate rollouts scheduled regionally to minimise disruption across a distributed network. Hardware ships from the Kendaall shop (see monitoring units, fuel sensors, and accessories), carries the standard hardware warranty, and stays covered under the repair & maintenance service, with transfer support available whenever a set is sold or redeployed to another site.
| Genset Class | Recommended Configuration | Primary Outcome |
|---|---|---|
| Standby sets (offices, institutions) | Runtime + mains-sense + fuel sensor | Changeover assurance, fuel control |
| Hire fleet sets | Runtime + GPS inventory + fuel sensor | Telemetry-backed billing, live inventory |
| Telecom / borehole sites | Runtime + fuel + delivery verification | Estate fuel-loss elimination |
| Portable & towable sets | Compact unit + movement alarms + battery backup | Theft protection and recovery |
| Prime-power plant rooms | Full suite + load-band logging | Cost-per-kWh truth, service by hours |
Compatibility note: the platform instruments the genset independently of its control electronics, so it fits engines and controllers from manufacturers such as Perkins, Cummins, CAT, FG Wilson, and Lister, alongside the wider range of Chinese-market sets common on East African sites. Where a digital controller such as a Deep Sea Electronics or ComAp unit is already fitted, Kendaall can read its data as an additional layer rather than replacing it.
What Generator Owners and Hire Companies Ask Before Fitting Monitoring
Will monitoring work on my generator’s make and size?
Yes — the platform instruments the genset independently rather than depending on its brand electronics, so it fits Perkins, Cummins, CAT, FG Wilson, Lister, and Chinese-market sets alike, from small portables to plant-room installations. Where a modern controller offers data (Deep Sea Electronics, ComAp, and similar), monitoring reads it as an additional layer; where the set is a bare engine and an alternator, Kendaall’s own sensors supply everything the dashboard needs.
Can it really verify that my night guard or caretaker isn’t running the genset privately?
Every crank event reports instantly with its timestamp, and each run is matched against the schedule defined for that genset — so an eleven p.m. two-hour run appears on the owner’s phone as it starts, and again in the weekly exception report with its fuel burn attached. Owners rarely need a confrontation; simply displaying the dashboard at the site tends to end the practice within days. The record remains available if a conversation is needed.
How does the hire billing feed work if the genset is on my client’s site?
The monitoring unit reports over the mobile network directly to the hire company’s own dashboard — the client’s site, Wi-Fi, and staff are not part of the data path. True hours, fuel, and location are visible for every set on hire, per-contract ledgers accumulate automatically, and month-end invoices attach the telemetry statement. Disputed meter readings end because there is no longer a meter to dispute — there is an independent feed.
What happens during network outages at remote sites?
The monitoring unit buffers all data — runtime, fuel, events — through coverage gaps and uploads on reconnection, so records stay complete even at sites with unreliable signal. Alerts queued offline transmit the moment any network returns. For permanently off-network sites, satellite-fallback hardware is available; this can be discussed when requesting a quote.
What does generator monitoring cost, and what’s the payback?
Configuration drives cost: runtime-only units sit at the entry tier, fuel sensing adds the calibrated sensor, and mains-sense or load logging add wiring time rather than significant hardware. Per-set pricing is on the pricing page, with estate volume rates available from five sets. Payback concentrates in fuel: on any set moving meaningful diesel, the first verified delivery or first exposed siphoning event typically covers several months of subscription — hire companies commonly see it within the first billing cycle instead.
We run vehicles, machines, and generators. Can everything live in one account?
Yes — that is the design. Gensets appear beside trucks, heavy machinery, and cars in one fleet management account, each asset class carrying its own data layers and rules, with consolidated fuel and cost reporting across the whole estate. Mixed estates also qualify for combined volume pricing.
Do you monitor the automatic transfer switch itself, or just the generator?
Mains-sense wiring connects at the automatic transfer switch, so the platform sees both sides of a changeover event: the moment mains power drops, the moment the genset starts and picks up the load, and the moment mains power returns and the switch changes back. This is what makes a per-blackout report possible rather than a simple “did it run” record.
Can monitoring tell the difference between an idle generator and one under real load?
Where the genset’s controller or charging circuit exposes load data, the platform logs load-band information alongside runtime, so an hour spent idling is separated from an hour spent carrying a full building’s load. This matters for fuel-burn benchmarking, since an idling set and a loaded set have very different expected consumption, and treating them identically would make the burn-rate alarms far less accurate.
How quickly will I see the first useful alert after installation?
Most clients see their first meaningful signal — an unscheduled start, an unexpected fuel drop, or a delivery reconciliation — within the first two weeks of live monitoring, because the behaviours these modules are designed to catch tend to be habitual rather than one-off. A caretaker running private jobs, a driver skimming diesel on delivery, or a fault in the auto-start sequence all tend to recur on their own schedule, which the platform is built to notice quickly.
Does fitting a monitoring unit affect my generator’s warranty?
No. Installation taps into existing battery, control, and charging circuits rather than modifying the engine or alternator itself, and is carried out by certified technicians using standard low-voltage wiring practice. Manufacturer warranties on the genset itself are unaffected; the monitoring unit carries its own separate hardware warranty.
Can I monitor a generator I don’t own, such as a landlord’s or a client’s set?
Yes, with the owner’s consent. This is a common arrangement for tenants running critical operations — a cold room or server room, for example — inside a building whose backup generator is owned and maintained by the landlord. A dedicated monitoring unit gives the tenant independent visibility into whether the changeover actually worked during a blackout, without requiring any change to the landlord’s own maintenance arrangements.
What size of generator can Kendaall’s platform monitor?
The platform is deployed across sets ranging from 5kVA portable units used at events and on small construction sites to 2,000kVA plant-room installations serving hospitals, telecom hubs, and large industrial sites. Sensor and wiring specification scales with the genset’s tank size, panel type, and duty classification, which is confirmed during the site survey ahead of installation.
How does generator monitoring differ from vehicle GPS tracking?
Vehicle tracking measures movement — distance, route, and speed — because a vehicle’s entire purpose is to move. A generator’s entire purpose is to stay in place and produce power, so its monitoring priorities invert: runtime hours, fuel consumption, and mains-failure response replace distance and route as the primary data layers, while GPS position becomes a security feature guarding against the one movement event that should never happen rather than the central measurement.
Instrument Every Genset Before the Next Delivery, the Next Hire, the Next Blackout
Provide the sets in operation — make, size, duty role (standby, prime power, hire), and site location — and Kendaall will return a per-set configuration and price against the fuel, hours, and risk it will begin reporting on day one.
