Howard from Marlboro, NJ has been a Green Sun Energy Services client since October of 2020. The load survey came to 2,298 square feet, and the Generac commissioned in June of 2021 is rated 16 kW on either fuel, so nothing is given up by running it on natural gas. A 200-amp automatic transfer switch carries the whole panel rather than a nominated handful of circuits. Remote monitoring came with the service cover, and the machine has been through every scheduled visit from the one-year service in May of 2022 to the five-year service in March of 2026.

Standby generator questions from Marlboro homeowners
Does a propane generator need permits in Marlboro?
A permanently installed propane generator normally requires construction permits, and the propane installation has to satisfy the applicable fuel-gas and LP-gas requirements. Tank placement, capacity, piping, regulators, setbacks and fire-safety provisions all come under review.
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.
Is the output the same on propane and natural gas?
Not necessarily. Many models are rated differently depending on fuel; a current 22 kW machine is rated 22 kW on LP and 21 kW on natural gas. The model-specific ratings should be compared before the generator is sized, not afterwards.
