Stuart and Celia from Long Branch, NJ have been Green Sun Energy Services clients since September of 2020. A Generac Guardian rated 18 kW on propane and 17 kW on natural gas went in during June of 2022, running on natural gas behind a 200-amp automatic transfer switch, with 1,520 square feet of living space behind it on the load survey. Eighteen kilowatts on a house that size is sized to the loads rather than to the floor area, and the 200-amp switch carries the service whole.

Standby generator questions from Long Branch homeowners
Does the clearance apply to a fixed window as well as one that opens?
A permanently fixed pane may be treated differently from an operable window, because the concern in the placement guidance is exhaust and carbon monoxide entering the building. Even so, the installer has to evaluate the exact model's manual and everything nearby -- operable windows, doors, vents, fresh-air intakes, window wells and mechanical openings. A fixed window should never simply be assumed acceptable.
Why does the generator run when the power is on?
It is performing its automatic exercise cycle, which confirms basic engine operation and keeps the machine ready. A generator can also start because utility voltage has become abnormal even though the power has not gone off completely -- the controller watches the quality of the supply, not simply whether it is absent.
Can the existing natural-gas service in a Long Branch 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.
