Anthony from Manasquan, NJ has been a Green Sun Energy Services client since September of 2021. The generator was commissioned in July of 2022: a Generac Guardian rated 21 kW on natural gas, sited on the right side of the house, with a 200-amp service-entrance switch and two smart management modules. The load calculation asked for 20 kW across 3,800 square feet, and the list explains it – a double electric oven, two refrigerators, a separate freezer, a sump pump, a washer, a gas dryer and a dishwasher. Cold storage and a sump between them are what make a long outage expensive in a house this size, and they are the reason the machine was sized to carry everything rather than a chosen few circuits. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Manasquan 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.
Does the generator need its own gas shutoff?
The fuel installation has to include the shutoff arrangements required by the adopted fuel-gas code and by the installation instructions. The valve must be positioned where it is accessible, both for servicing and for isolating the machine in an emergency.
What does a whole-house generator actually mean?
Whole-house generally means the transfer equipment serves the home's main electrical system rather than a small emergency-circuit panel. It does not promise unlimited capacity. High-demand appliances may still be prioritized or briefly shed while generator capacity is being used elsewhere.
