22 kW Standby Generator Installation in West Windsor, NJ | Whole-House Backup

West Windsor, NJ · Client since August 2019

Samantha from West Windsor, NJ has been a Green Sun Energy Services client since August of 2019. The generator was commissioned that November: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp whole-house transfer switch. The load calculation asked for 15 kW across the 3,300 square foot house, so the machine carries a comfortable margin over the requirement – a generator asked for well under what it can produce runs cooler and wears its parts more slowly than one working at the edge of its rating. A refrigerator, a separate freezer, a washer, a gas dryer and a dishwasher make up the load. Seven years on, annual maintenance, an extended parts-and-labor warranty and monitoring we manage all still sit behind it.

Standby generator questions from West Windsor homeowners

Will a 22 kW generator run an entire West Windsor house?

For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.

Can the generator run the propane tank right down?

It is a poor outage plan. Propane should be monitored and topped up before the generator runs out. Usable capacity is not the same as the tank's nominal water capacity, and cold weather reduces how much vapour the tank can deliver just when the machine is working hardest.

Can a generator be installed in a flood zone in West Windsor?

Yes, but the generator and its electrical equipment may need to be elevated or otherwise protected. The installation is evaluated against the property's FEMA flood zone, its Base Flood Elevation and Design Flood Elevation, the municipal flood ordinance, any applicable freeboard, and NJDEP requirements where they apply. It is a property-by-property assessment rather than a rule of thumb.
