Charlie from Red Bank, NJ has been a Green Sun Energy Services client since May of 2021. The generator was commissioned that October: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with a smart management module. The load calculation asked for 17 kW across the 3,600 square foot house – two sump pumps, a double electric oven, three refrigerators, a washer, a gas dryer and a dishwasher. A double oven and three refrigerators together are what lift the figure well past what the floor area alone would suggest, and the management module is what lets a single machine carry all of it without being sized for everything starting at once. Annual maintenance, a ten-year extended parts-and-labor warranty and monitoring we manage all sit behind it.

Standby generator questions from Red Bank homeowners
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.
Can Red Bank require a generator to sit farther from the house than the manufacturer does?
Yes. Another applicable requirement can result in greater separation than the manufacturer's listed minimum -- equipment may be permitted eighteen inches from a qualifying wall while the local ordinance requires several feet from a property line. Both requirements have to be satisfied; neither cancels the other.
What is Base Flood Elevation and why does it matter here?
Base Flood Elevation is the elevation associated with the base flood -- generally the flood with a one percent chance of being reached or exceeded in any year. For a generator it is often the starting point for working out how high the mechanical and electrical equipment has to be protected or raised.
