Thomas from Monroe Township, NJ has been a Green Sun Energy Services client since January of 2022. The generator was commissioned that July: a Generac Guardian rated 17 kW on natural gas, on a 150-amp service-entrance switch with a smart management module and surge protection. The load calculation asked for 15 kW across the 1,886 square foot house, where an electric dryer and a separate freezer do more to set the number than the floor area does. An electric dryer alone draws roughly five times what a gas one does, which is why two houses of the same size can need very different machines. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Monroe Township homeowners
Can the existing natural-gas service in a Monroe Township 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.
Can a standby generator backfeed the utility lines?
A properly installed and functioning automatic transfer system is designed to prevent it. That is the point of the transfer switch: it stops generator power reaching the utility supply, where it could endanger line workers and damage equipment. Backfeeding is a risk of improvised connections, not of a correctly installed system.
