22 kW Generac standby generator in Rumson, NJ by Green Sun Energy Services.
Barbara from Rumson, NJ has been a Green Sun Energy Services client since October of 2023. The generator was commissioned that December, on a managed whole-house switch, sized against a 16 kW calculation for the 1,850 square foot house, with an electric dryer, two refrigerators, a washer and a dishwasher on the load list. The contract carried an unusual clause: the household could cancel without penalty by a named date if the final location or the final cost turned out unacceptable once the survey work was done. That is a fair way to handle the two things nobody can settle before a site visit – where the machine will actually go, and what the groundwork to get it there will cost – and it puts the risk of an unwelcome answer on us rather than on the customer. Annual maintenance, a ten-year extended parts-and-labor warranty and monitoring we manage all sit behind it.

Standby generator questions from Rumson homeowners
Can the existing natural-gas service in a Rumson 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.
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.
How much space is needed at the ends of the generator?
Applicable air-cooled installation instructions commonly require about three feet at the ends. That space protects cooling airflow, exhaust operation and the access a technician needs to work on the machine. The model-specific manual controls.
