Martin from Fair Haven, NJ has been a Green Sun Energy Services client since April of 2026. We installed a 22 kW Generac in June, making 21 kW on the natural gas it runs on here, switching the whole house through a 200-amp service-entrance transfer switch with surge protection built in. At 3,800 square feet this is a large house, and the code calculation put the minimum at 16 kW, so the machine that went in carries a comfortable margin above what the arithmetic required. Two refrigerators and a sump pump are the loads that decide whether an outage is an inconvenience or a problem, and load management modules keep the heaviest of them from starting against each other. Our top service plan supports it, with annual maintenance, an extended parts-and-labor warranty and remote monitoring that Green Sun manages directly.

Standby generator questions from Fair Haven homeowners
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.
Can a generator be installed on a deck or a roof?
Platform, deck and supporting-structure installations are recognized, but they call for additional review: structural capacity, noncombustible surface requirements, fire clearance, exhaust, airflow, vibration, service access and local requirements all have to be addressed. It is a site-specific installation rather than a routine location.
Why does the generator run when the power is on?
It is performing its automatic exercise cycle, which confirms basic engine operation and keeps the machine ready. A generator can also start because utility voltage has become abnormal even though the power has not gone off completely -- the controller watches the quality of the supply, not simply whether it is absent.
