Alan from Barnegat, NJ has been a Green Sun Energy Services client since March of 2021. The generator was commissioned that November: 18 kW on natural gas, on a 200-amp managed whole-house switch with a smart management module, sized against a 16 kW calculation for the 3,000 square foot house. An electric dryer, a sump pump, a refrigerator, a washer and a dishwasher make up the load. Eight months separated the contract from the commissioning, which was the shape of generator work through that period – the permit, the utility gas connection and the equipment lead time all ran in sequence rather than together. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage all sit behind the machine.

Standby generator questions from Barnegat homeowners
Will a 22 kW generator run an entire Barnegat 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.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
What does a standby generator sit on?
A stable, level support system allowed by the model's installation instructions. Depending on the machine and the site that can be an approved composite base, a prepared aggregate base, a concrete pad, or an engineered elevated platform.
