22 kW Generac standby generator in Middletown, NJ by Green Sun Energy Services.
Kenneth from Middletown, NJ has been a Green Sun Energy Services client since October of 2020. The generator was commissioned in April of 2021, sized against a 19 kW calculation for the 4,000 square foot house, with an electric oven, an electric dryer, a sump pump and two refrigerators on the load list. Two things were agreed before the contract was signed: the gas and electrical lines would be surface mounted rather than concealed, and the ground where the generator would sit would be levelled in advance. Surface-mounted conduit is the honest option on a house where concealing it would mean opening walls, and saying so in the quotation means nobody is surprised by how the finished job looks. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Middletown homeowners
Can the existing natural-gas service in a Middletown home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
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 the residential building code apply to a generator?
It can. For applicable one- and two-family dwellings New Jersey adopts the 2024 International Residential Code, subject to state amendments. Structural and flood-related generator installations may therefore need review under the residential subcode as well as the electrical and fuel requirements.
