Alice and Vincent from Whiting, NJ have been Green Sun Energy Services clients since August of 2022. The generator was commissioned that October: a 14 kW Generac Guardian on natural gas, on a 200-amp whole-house transfer switch with a smart management module and surge protection. The load calculation asked for 13 kW across the 1,800 square foot house – a refrigerator, a washer, a gas dryer and a dishwasher – so the machine matches the requirement closely rather than exceeding it, which is the sensible answer when a house has a modest and well-understood load. The generator is supported by annual maintenance, a ten-year extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Whiting homeowners
Can the existing natural-gas service in a Whiting 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.
What happens if we add a heat pump, a pool or an EV charger later?
Any major new electrical load should prompt a review of the generator's capacity. A machine sized correctly at installation may no longer be adequate once substantial loads are added. Load management can often accommodate the new equipment without replacing the generator.
Which fuel-gas code applies?
New Jersey currently adopts the 2024 International Fuel Gas Code as its Fuel Gas Subcode, which is what governs the piping, testing and shutoff arrangements on a natural-gas generator installation.
