Robert from Beach Haven, NJ has been a Green Sun Energy Services client since May of 2021. The Generac 7042-2 at the house is rated 22 kW on propane and 19.5 kW on natural gas, runs on natural gas, and feeds a 100-amp transfer switch. It was installed in April of 2021. Green Sun has serviced it every year since – May of 2021, April of 2022, April of 2023, April of 2024, February of 2025 and February of 2026 – and it reports to remote monitoring in between. Beach Haven is on Long Beach Island, where salt air works on an enclosure all year and the storm season is the whole reason the machine is there.

Mike did an excellent job servicing our generac backup generator. He is knowledgeable and courteous, explained his work, and was thorough and efficient.
Green Sun Energy Services replied
Thank you, and Mike will be glad to hear it. Knowing the machine and explaining it are two different skills, and a good service visit needs both. Thank you for trusting Green Sun Energy Services with the Generac, and for taking the time to write.
Standby generator questions from Beach Haven homeowners
Can the existing natural-gas service in a Beach Haven 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.
Can the generator run the propane tank right down?
It is a poor outage plan. Propane should be monitored and topped up before the generator runs out. Usable capacity is not the same as the tank's nominal water capacity, and cold weather reduces how much vapour the tank can deliver just when the machine is working hardest.
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.
