Green Family Limited Partnership in Farmingdale, NJ has been a Green Sun Energy Services client since October of 2024. The generator was commissioned in January of 2025: a Generac Guardian rated 19.5 kW on natural gas, on a 150-amp service-entrance switch with a smart management module and surge protection. The load calculation asked for 18 kW across 2,800 square feet, with an electric dryer and an electric oven among the appliances. For a property held in a partnership rather than by an owner-occupier, backup power is an asset decision as much as a comfort one: the building has to stay habitable and insurable whether anyone is on site or not. Annual maintenance, a seven-year extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Farmingdale homeowners
Does new gas piping have to be pressure tested in Farmingdale?
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.
Can an existing propane tank be reused for a new generator?
Possibly. Existing propane equipment can be reused when it is correctly sized, sited, regulated, maintained and capable of supplying the demand the generator adds. The propane supplier should verify capacity and regulator performance before the machine is commissioned rather than after.
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.
