Silke from Freehold, NJ has been a Green Sun Energy Services client since October of 2024. The machine is a Generac 7223 rated 14 kW on natural gas, on a 100-amp transfer switch, and it was commissioned in February of 2025. The house is about 1,500 square feet. A February commissioning is worth noting: the gas pressure test and the first load test are done in the cold, which is the condition the machine will actually be asked to start in.

Standby generator questions from Freehold homeowners
What is Base Flood Elevation and why does it matter here?
Base Flood Elevation is the elevation associated with the base flood -- generally the flood with a one percent chance of being reached or exceeded in any year. For a generator it is often the starting point for working out how high the mechanical and electrical equipment has to be protected or raised.
Does a generator produce less on natural gas than on propane?
Some models do have a lower rated maximum output on natural gas than on propane -- a current 22 kW machine is rated 22 kW on LP and 21 kW on natural gas. Other models carry their own ratings, so the model-specific specification sheet is what settles it rather than a general rule.
Can the existing natural-gas service in a Freehold 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.
