Michael from Red Bank, NJ has been a Green Sun Energy Services client since October of 2020. The generator was commissioned in June of 2021: 20 kW on natural gas, on a 200-amp whole-house transfer switch, sized against a 14 kW calculation for the 2,600 square foot house. Two sump pumps are the load that matters here. A house with one pump has a wet basement problem; a house with two has already been told by experience that one is not enough, and both will want to run in the same storm that takes the power out. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the generator.

Standby generator questions from Red Bank homeowners
Does the transfer switch need flood protection as well as the generator?
Yes. A flood review should cover much more than the generator enclosure. FEMA recommends that a residential standby system consider elevation or protection of the generator, the transfer switch, the normal and emergency panels, the feeders and the control wiring together.
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.
Will a larger gas meter be needed?
Possibly. A generator can significantly increase a home's maximum gas demand. If the existing meter or service cannot hold the required pressure while supplying the generator and the other appliances together, the gas utility may require an upgrade.
