22 kW Generac standby generator in Middletown, NJ by Green Sun Energy Services.
Peter from Middletown, NJ has been a Green Sun Energy Services client since August of 2020. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in the following January, running on natural gas behind a 200-amp automatic transfer switch, with 3,200 square feet of living space behind it on the load survey. At 22 kW behind a service-sized switch the machine is not carrying a shortlist of circuits, it is carrying the house – which is what the survey found it needed.

Standby generator questions from Middletown homeowners
How far does a generator have to be from a window or door?
Manufacturer guidance requires substantial separation from operable windows, doors, vents and other openings through which exhaust could enter the house -- commonly five feet for the applicable air-cooled configurations. The exact model's current installation manual has to be checked before a location is approved.
Will a 22 kW generator run an entire Middletown 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.
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.
