Fred from Maplewood, NJ has been a Green Sun Energy Services client since November of 2021. The generator was commissioned in March of 2022, on a managed whole-house switch, sized against a 14 kW calculation for the 2,420 square foot house. Three things were agreed before the work, and the third is the one worth noting: the household would have the Verizon box moved and repair the cut sheetrock in the back room, and Green Sun would install a new earth ground at no charge. An earth ground is what gives fault current somewhere to go, and an older house often has one that no longer meets code. Finding that at survey and fixing it without adding it to the price is the sort of thing that never appears in an advertisement. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Maplewood 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 Maplewood?
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.
