Portable generators
A portable unit is the smallest thing worth renting: two people can move it, it plugs into cord-connected loads, and it runs a handful of circuits rather than a building.
Equipment
Generator types explained
Rental categories are not marketing labels. Each one exists because of a real constraint: noise, fuel, runtime, portability or load size.
Choose a category
Inverter generators
Inverter units convert engine output to DC and back to a tightly regulated AC waveform. You rent one for two reasons: noise and power quality.
Towable diesel generators
A towable genset is a diesel engine, alternator, control panel and fuel tank on a trailer. It is built for continuous duty measured in weeks, not an afternoon.
Natural gas generators
A gas-fuelled unit removes the fuel truck from the equation. Where a pipeline connection is available, runtime stops being a scheduling problem.
Solar and battery power
Battery systems are rated in stored energy, not just output. That single difference changes how you plan the job.
| Type | Typical range | Usual fuel | Best for |
|---|---|---|---|
| Portable | 2 - 15 kW | Gas / dual fuel | Tools, RVs, home essentials |
| Inverter | 2 - 10 kW | Gas / propane | Electronics, events, quiet sites |
| Towable diesel | 20 - 150 kW | Diesel | Job sites, long rentals |
| Natural gas | 20 - 400 kW | Pipeline gas | Long facility jobs |
| Solar & battery | Storage rated in kWh | Stored energy | Silent, zero-emission work |
Do
- Match the type to the duty cycle, not just the wattage
- Ask what fuel policy applies and who refuels
- Confirm noise ratings if you are near homes or a venue
- Budget for cable and distribution as separate items
Don’t
- Assume a portable unit can carry a whole house
- Rent on peak watts alone and ignore motor starting
- Skip site access checks for a towable unit
- Connect anything to a building panel yourself
