William from Bayville, NJ has been a Green Sun Energy Services client since February of 2022. The machine is a Generac 7209 rated 24 kW on propane and 21 kW on natural gas, running on natural gas, on a 150-amp transfer switch, and it was commissioned in August of 2022. Bayville is close enough to the water that an outage here is usually a weather event rather than a fault on the line, which is the case a standby machine is bought for. Green Sun has serviced it in August of 2023, August of 2024 and September of 2025, and it reports to remote monitoring in between.

Standby generator questions from Bayville homeowners
Will a 22 kW generator run an entire Bayville 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.
How quickly does it take over?
The automatic start sequence normally begins within seconds of the controller deciding that utility power has failed or fallen outside acceptable limits. There is a deliberate short delay so that a momentary flicker does not trigger a full start and transfer. Exact timing depends on the controller, the transfer switch and the configuration.
