Lara from Allenhurst, NJ has been a Green Sun Energy Services client since June of 2025. The generator was commissioned in July: 18 kW on natural gas, on a 200-amp service-entrance switch with two load management modules and surge protection. The load calculation asked for 14 kW across the 2,700 square foot house, so the machine sits comfortably above what the code requires. Allenhurst is a single square mile on the ocean, and the surge protection matters as much as the generator itself here – power coming back after a coastal storm is rarely clean, and the moment the grid returns is when connected equipment is most exposed. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Allenhurst homeowners
How much room does a technician need around the machine?
Enough to satisfy the model-specific service clearances and to open the enclosure and remove service panels safely. Routine work reaches the engine, air filter, oil filter, spark plugs, battery, controller, fuel system and wiring compartments, so the space has to be real rather than nominal.
What happens when the utility power comes back?
The system detects the return of acceptable utility power and transfers the house back automatically. The generator then runs through a programmed cool-down before shutting off and returning to standby. Nobody has to switch anything back by hand.
Will an 18 kW generator run an entire Allenhurst house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
