Anthony from Lincroft, NJ has been a Green Sun Energy Services client since September of 2025. The generator was commissioned that December: a Generac Guardian rated 22.5 kW on the natural gas it runs on, tied to a 400-amp smart transfer switch outdoors beside the meter, with three load management modules and surge protection. The load calculation set an 18 kW minimum for a 4,734 square foot house carrying two sump pumps, two refrigerators, a washer, a gas dryer and a dishwasher, so there is headroom rather than rationing when the power drops. Annual maintenance keeps it serviced, and monitoring we manage means a fault reaches us rather than waiting to be noticed.

Standby generator questions from Lincroft homeowners
Does new gas piping have to be pressure tested in Lincroft?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
How close to the house can a generator sit in Lincroft?
For the air-cooled models covered by the manufacturer's listed installation guidance, the rear of the generator can be as close as eighteen inches to a qualifying structure when every condition of that listing is met. That eighteen inches is a tested installation dimension, not a zoning setback, and a municipality can require more.
Will it work if nobody is home?
Yes, which is one of the main advantages over a portable generator. It has to be properly installed, fuelled, maintained, free of active shutdown alarms and left in AUTO. That matters most where an outage would otherwise stop a sump pump, the heating, refrigeration or a well pump while the house is empty.
