Charles from Lawrenceville, NJ has been a Green Sun Energy Services client since March of 2023. The generator was commissioned in June, sized against a 20 kW calculation for the 4,600 square foot house, with two sump pumps, an electric oven, two refrigerators and a separate freezer on the load list. One condition was agreed before the work: a tree stump had to be ground out and the ground levelled where the generator would sit. A generator needs a flat, stable base that will still be flat in ten years, and a rotting stump underneath is not that – it is the sort of groundwork better settled in the contract than discovered on installation day. Annual maintenance, a ten-year extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Lawrenceville homeowners
Why do outages last longer on some Lawrenceville streets than others?
Mature tree cover over overhead lines is the usual reason. Limbs coming down in wind, snow or ice take the lines with them, so heavily treed streets tend to see both more frequent outages and longer restoration times than open ones. It is one of the honest arguments for standby power rather than a portable generator.
Should gas pressure be checked while the generator is running?
Yes. Operating pressure means more than a static reading taken with the generator off. The fuel system has to hold adequate pressure while the generator runs and other appliances may also be drawing gas. That matters most when an existing residential service is being reused.
What is a standby generator?
A permanently installed automatic backup-power system that supplies electricity to the house when utility power is unavailable. Unlike a portable, it is permanently connected to the home's electrical system through transfer equipment and normally runs on natural gas or liquid propane. When the power fails it starts on its own, carries the connected loads, and hands the house back to the utility once service returns.
