John from New Providence, NJ has been a Green Sun Energy Services client since September of 2020. The machine is a Generac 7039-1 rated 20 kW on propane and 18 kW on natural gas, running on natural gas, on a 200-amp transfer switch. It was commissioned in May of 2021. A 200-amp whole-house switch on a house of about 2,800 square feet means the panel transfers exactly as it stands. Green Sun has serviced it in May of 2022, July of 2023, August of 2024 and July of 2025, and it is on remote monitoring in between.

Standby generator questions from New Providence homeowners
How much space does a generator need in front of it?
For applicable air-cooled installations, roughly three feet of unobstructed clearance at the front, for airflow and for servicing. Fences, shrubs and stored materials should not intrude into that space. Newer models should be checked against their own current manual.
What does a whole-house generator actually mean?
Whole-house generally means the transfer equipment serves the home's main electrical system rather than a small emergency-circuit panel. It does not promise unlimited capacity. High-demand appliances may still be prioritized or briefly shed while generator capacity is being used elsewhere.
Can the existing natural-gas service in a New Providence home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
