Siobhan from Whiting, NJ has been a Green Sun Energy Services client since March of 2023. The machine is a Generac 7042-2 rated 22 kW on propane and 19.5 kW on natural gas, running on natural gas, on a 150-amp transfer switch, and it was commissioned in May of 2023. The house is about 1,375 square feet, which is small for a 22 kW machine and is the right answer anyway: the size follows the equipment that has to start, and a compact house with central air and a well asks for as much starting current as a large one.

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.
Can we plant shrubs or put a fence around the generator?
Yes, provided the planting or fence stays outside the required airflow and service clearances. Site-selection guidance treats shrubs, bushes and trees as part of the clear space around the machine, and clearance should be measured against how the planting will grow rather than how it looks the week it goes in. Local zoning may separately require screening.
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.
