22 kW Generac standby generator in Leonardo, NJ by Green Sun Energy Services.
Joanne and Howard from Leonardo, NJ have been Green Sun Energy Services clients since December of 2024. The generator was commissioned in March of 2025: a Generac Guardian rated 22 kW on natural gas, outdoors beside the meter, with a 200-amp service disconnect, two load management modules and surge protection. The load calculation asked for 17 kW across the 2,630 square foot house, with two refrigerators, an electric oven, a washer, a gas dryer and a dishwasher to carry. Leonardo sits low and close to the bay, which is exactly the geography that loses power in a storm and stays out longest, since the crews have to work their way down from the main lines before anyone this far out sees the lights come back. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Leonardo homeowners
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.
Can the generator be connected to any nearby gas pipe?
No. The branch supplying the generator has to be sized for the flow and pressure the machine needs. A pipe that happens to be close by may be too small, or may already be carrying too much load. Undersized piping shows up as poor starting, unstable running, reduced output or a generator that shuts down under load.
Will a 22 kW generator run an entire Leonardo 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.
