Chris from Freehold, NJ has been a Green Sun Energy Services client since October of 2020. The generator was commissioned in June of 2021: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules, sized against a 16 kW calculation for the 4,000 square foot house. A well pump, a refrigerator, a separate freezer, a washer, a gas dryer and a dishwasher make up the load – and the well is what makes backup power a necessity rather than a comfort, since no power means no water at all. The house directly opposite went in on the same day, which is the sensible way to do it: one site visit, one round of utility coordination and one crew covering both. An annual maintenance plan covers the generator.

Standby generator questions from Freehold homeowners
Does new gas piping have to be pressure tested in Freehold?
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 much propane does a generator use?
It depends on the model and on the electrical load. For a current 22 kW machine the published figures are roughly 2.45 gallons of LP an hour at half load, and about 135 cubic feet of LP vapour an hour at full load. Real consumption moves with what the house is actually drawing.
Which fuel-gas code applies?
New Jersey currently adopts the 2024 International Fuel Gas Code as its Fuel Gas Subcode, which is what governs the piping, testing and shutoff arrangements on a natural-gas generator installation.
