Kim from Farmingdale, NJ has been a Green Sun Energy Services client since February of 2022. A Generac model 7042-2 was commissioned that March, rated 19.5 kW on natural gas where the load calculation asked for 15 kW. The house heats on a hydronic boiler and draws its water from a well, and both of those become electrical problems during an outage: a boiler will not circulate without power, and a well pump will not lift. A load-management module and a surge protective device went in with the machine on a 200-amp service, and our top-tier plan supports it with an annual visit, an extended parts-and-labor warranty and remote monitoring we manage directly.

Standby generator questions from Farmingdale homeowners
Does a propane generator need permits in Farmingdale?
A permanently installed propane generator normally requires construction permits, and the propane installation has to satisfy the applicable fuel-gas and LP-gas requirements. Tank placement, capacity, piping, regulators, setbacks and fire-safety provisions all come under review.
Will a larger gas meter be needed?
Possibly. A generator can significantly increase a home's maximum gas demand. If the existing meter or service cannot hold the required pressure while supplying the generator and the other appliances together, the gas utility may require an upgrade.
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.
