Peter from Port Monmouth, NJ has been a Green Sun Energy Services client since June of 2023. The Generac 7043-2 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 2022 by another company. Green Sun took it on the following year and has serviced it each spring since – June of 2023, June of 2024, May of 2025 and April of 2026. Port Monmouth sits on the bay, where an outage is more often weather than a fault on the line.

Standby generator questions from Port Monmouth homeowners
Can the existing natural-gas service in a Port Monmouth 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.
What is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
Why does cold weather matter when sizing a propane tank?
Because propane's ability to vaporise falls as the outdoor temperature drops and as the liquid level in the tank falls. A supply that looks adequate in mild weather can struggle to support a large generator through a long winter outage if storage and vaporisation capacity were not designed for it.
