GENERATOR TRACKING
Track every generator. Bill every engine hour.
GPS tracking and runtime monitoring for generator rental fleets — portable and towable units. Monitor engine hours, bill on actual runtime, recover stolen units, and trigger maintenance by hours, billed per asset at $13/month — not per yard.
The short answer
What is the best way to track rental generators?
Rental generators are tracked with a GPS device that also captures engine runtime, so you can monitor actual run hours, bill rentals on real usage, and recover stolen units. Hapn tracks generators on its equipment tier at $13/month per unit for GPS plus runtime and utilization, or $18/month for full engine telematics (fault codes and fuel data) — billed per asset, not per yard. Theft alerts fire on geofence and after-hours movement, and maintenance triggers fire off engine hours. Two ways to buy: a 3-year plan with all hardware free, or no-contract month-to-month where you own the hardware.
- Monitor engine runtime (hours) on every unit, not just location
- Automate rental billing from actual run hours instead of flat day rates
- Geofence and after-hours alerts flag theft, with location for recovery
- Fire fuel and maintenance triggers off engine hours, not guesswork
- Equipment tracking at $13/asset/month — billed per asset, not per yard
- All hardware free on a 3-year plan, or own it outright month-to-month
Generators track on Hapn’s equipment tracking tier, with Hapn Zones (BLE) as a secondary option for small units stored in the yard. For background, see generator GPS tracking and the complete guide to renting a generator.

Key terms
How generator tracking actually works
Three terms that define how rental operators track powered generators.
Engine-hour billing
Engine-hour billing charges a generator rental on the hours its engine actually ran, captured by a tracker that detects run-time, rather than on a flat daily or weekly rate. It lets rental companies invoice true usage, catch off-contract overtime, and protect warranties tied to service-hour thresholds — turning metered runtime into a defensible line on the invoice.
Runtime monitoring vs telematics
Runtime monitoring captures engine on/off and cumulative run hours from a GPS device — enough to bill on usage and schedule maintenance ($13/mo tier). Telematics goes further, reading the generator controller or CAN bus for fault codes, fuel level, voltage, and load ($18/mo tier). Most rental fleets start with runtime and add telematics on higher-value units.
Per-asset vs per-site pricing
Per-asset pricing charges a flat rate for each tracked generator, wherever it sits. Per-site pricing — common in rental and asset software — charges by location, so multi-yard operators pay a premium for every yard. Hapn bills per asset from $13/month, so a generator moving between yards and job sites never triggers a location surcharge.
WHAT GENERATOR FLEETS USE IT FOR
From unbilled hours to dollar-utilization
The jobs a generator rental operator actually buys tracking to do.
Monitor engine runtime
See actual run hours on every generator, not just where it is. Runtime data tells you which units are working, how hard, and when they are due for service — the foundation for usage billing, maintenance, and right-sizing the fleet.
Automate rental billing on runtime
Bill generator rentals on the hours the engine actually ran instead of a flat day rate. Reconcile metered runtime against the contract, catch off-contract overtime, and end disputes over usage with data your customer can see.
Prevent theft and recover units
Generators are among the most frequently stolen rental assets — portable, valuable, and easy to load. Geofences per job site and yard, plus after-hours movement alerts and a backup battery, flag a unit the moment it moves and give you location for recovery.
Trigger fuel and maintenance by hours
Set service intervals by engine hours, not calendar guesses, so a generator is rental-ready instead of red-tagged on a deadline. Runtime and (with telematics) fuel-level data flag refuels and oil changes before a no-start call comes in from the job site.
Maximize fleet utilization
See what share of your generator fleet is out earning versus sitting idle in the yard, measured by runtime and on-rent status. Right-size purchasing with real data and move units to where demand is instead of buying iron you already own but cannot see.
See every yard on one platform
Multi-yard rental operators and dealer networks see the whole fleet in one view — which generators sit at which yard and which are on rent — without calling branches to chase a unit. One login, one platform, billed per asset.
THE PROBLEM
What untracked generators cost you
Generators run unbilled hours, walk off job sites, and sit idle across yards.
Hours you never bill
Generators run nights, weekends, and past the contract on usage you never invoiced. Without runtime data you bill a flat day rate while the engine logs hours you can neither charge for nor tie to a warranty claim.
Units that walk off
Portable and towable generators are easy to load and quick to disappear from a job site. Without location and after-hours alerts, a theft is invisible until the unit fails to come back at end of rental.
Construction equipment theft costs U.S. operators up to ~$1B/year (NER/NICB).
Idle iron and per-site billing
A generator sitting unseen in one yard while another branch turns away rentals is margin left on the ground — and most rental and asset software charges per site, so multi-yard operators pay more to see more.
HOW IT WORKS
Live across every yard in days
Tell us your fleet
Portable and towable generators, their sizes and controllers, and the yards they move between. We recommend the right mix of GPS-plus-runtime trackers, engine telematics for higher-value units, and BLE for small units stored in the yard.
Tag and install
Attach a tracker for GPS and runtime, or wire telematics into the controller for engine data on bigger units. Rugged and weatherproof, with a backup battery so a unit keeps reporting even if power is cut.
Track, bill, and maintain
See location, engine hours, and on-rent status across every yard, get theft and maintenance alerts, and bill on actual runtime. Push it all to your rental software via the open API.
CAPABILITIES
Runtime, billing, theft recovery, and maintenance
Runtime & engine-hour monitoring
Accurate engine on/off and cumulative run hours on every generator. The foundation for usage billing, hours-based maintenance, and real utilization — so you manage the fleet on data, not the hour-meter someone forgot to read.
Automated rental billing on hours
Capture true run-time per unit and reconcile it against the rental contract. Bill on metered hours, catch off-contract use, and protect warranties tied to service-hour thresholds — without a tech walking the yard with a clipboard.
Theft recovery & geofencing
Real-time geofences per job site and yard, after-hours movement alerts, and a backup battery that keeps tracking if a thief cuts power. Location for recovery the moment a generator moves when it should be still.
Fuel & maintenance triggers
Set service intervals by engine hours, calendar, or diagnostic triggers, and get alerted before a threshold hits. With telematics, fuel-level data flags refuels before a no-start call comes in from the job site.
Engine telematics & fault codes
Step up from runtime to full engine data — fault codes, fuel level, voltage, and load — read from the generator controller or CAN bus on higher-value units. Diagnose issues remotely instead of rolling a truck to find out.
$18/mo telematics tier
Per-asset, multi-yard platform
Every yard on one platform, billed per asset from $13/month — not per site. BLE Zones adds yard-level visibility for small units stored indoors, and an open API pushes runtime and location into your rental software.
COMPARISON
Generator tracking: per-asset vs per-site software
Most rental and asset software charges per yard and stops at location. Hapn charges per asset, captures runtime — and publishes its pricing.

Pricing
Two ways to buy — pick your capital plan
Transparent per-asset pricing for generators and everything around them — billed per asset, not per yard. Lead with the free-hardware term, or stay flexible month-to-month.
All hardware free — zero upfront capex
Trackers, telematics harnesses, and BLE gateways are included at no cost on a 3-year term. The strongest reason generator fleets switch off a per-site quote-and-deploy vendor.
Buy hardware, stay flexible
Purchase devices outright and run month-to-month — you own the hardware. Scale tracking up and down with seasonal and storm-season demand, with no long-term commitment.

Generator tracking FAQ
Rental generators are tracked with a GPS device that also captures engine runtime, attached to each portable or towable unit. It reports real-time location and geofence alerts outdoors, logs engine on/off and cumulative run hours for billing and maintenance, and fires after-hours movement alerts for theft. Higher-value units can add telematics for fault codes and fuel level read from the controller.
