22 kW Generac standby generator in Middletown, NJ by Green Sun Energy Services.
Christine 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 that October, running on natural gas behind a 200-amp automatic transfer switch. The load survey put 5,000 square feet of living space behind it, which is what puts the machine at the top of the air-cooled range rather than in the middle of it – and with the switch sized to the whole service, an outage takes nothing off the table.
Why Christine chose Green Sun Energy Services
Complete backup power, from sizing and installation to the service that keeps it ready.

Standby generator questions from Middletown homeowners
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 is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
Can the generator go in the back yard?
Yes, provided the location complies with the installation instructions and the applicable state and municipal requirements. A distant back-yard position lengthens the electrical and gas runs, which can call for larger conductors or larger gas piping and can raise the cost of the installation.
