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
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.
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.
What size propane tank does a generator need?
Tank size follows the generator's capacity, the outage duration you want to cover, the climate, the tank's vaporisation capacity and any other appliances drawing off the same tank. Standby generator applications call for a substantial storage volume rather than a small portable cylinder, and the propane supplier's requirements form part of the design.
