Vasanthi 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. The calculation asked for 17 kW across the 4,000 square foot house, with a well pump, a refrigerator, a washer, a gas dryer and a dishwasher on the list. A well pump is the load that changes the character of an outage: the lights going out is an inconvenience, but a house on a well loses its water supply entirely at the same moment. The generator was installed the same day as the one across the road, both households having decided together. An annual maintenance plan covers the machine.

Standby generator questions from Freehold homeowners
What happens if the manufacturer and Freehold disagree?
The installation has to satisfy all applicable requirements. A manufacturer's listing cannot be ignored, and a manufacturer's minimum clearance does not cancel a municipal zoning requirement. Where requirements conflict or the interpretation is uncertain, the Authority Having Jurisdiction is consulted before the work goes in rather than after.
Can a generator be raised on a platform?
Yes. Manufacturer guidance specifically covers installations on platforms and other supporting structures, and directs them to the applicable fire-safety standard, including a noncombustible surface extending beyond the generator for the configuration addressed. Flood and structural requirements have to be satisfied as well.
Should gas pressure be checked while the generator is running?
Yes. Operating pressure means more than a static reading taken with the generator off. The fuel system has to hold adequate pressure while the generator runs and other appliances may also be drawing gas. That matters most when an existing residential service is being reused.
