Matthew from Belford, NJ has been a Green Sun Energy Services client since July of 2024. The generator was commissioned that November: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with surge protection. The load calculation asked for 18 kW across the 2,000 square foot house, which is a great deal for that floor area – a well pump, two sump pumps and an electric dryer between them account for most of it. Three pumps is what makes backup power a necessity rather than a comfort here: no power means no water coming into the house and no way to move it out, at the same moment. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Belford homeowners
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.
How can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
Does new gas piping have to be pressure tested in Belford?
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.
