Marilyn from Holmdel, NJ has been a Green Sun Energy Services client since August of 2020. She signed at the end of that August and the generator was commissioned the following March, a 20 kW Generac on a pad with a 200-amp service-rated transfer switch and three smart management modules to balance the heavy loads. A Generac service contract has kept it maintained since, with scheduled visits and remote monitoring so a fault turns up on a report rather than during a storm. Holmdel is in Monmouth County, where whole-house backup is closer to standard than luxury.

Standby generator questions from Holmdel homeowners
Will a 22 kW generator run an entire Holmdel 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.
Should gas pressure be checked while the generator is running?
Yes. Operating pressure means more than a static reading taken with the generator off. The fuel system has to hold adequate pressure while the generator runs and other appliances may also be drawing gas. That matters most when an existing residential service is being reused.
