Ruchir from Princeton, NJ has been a Green Sun Energy Services client since August of 2019. The 22 kW Generac at the house was serviced by us that month, four years after another company had installed it. It runs the whole house through a 100-amp transfer switch on natural gas. Four years is the age at which the battery and the spark plugs start to matter on a standby machine, and a service visit is the only thing that finds either of them before an outage does.

Standby generator questions from Princeton homeowners
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.
Will a 22 kW generator run an entire Princeton 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.
Can the exercise time be changed?
Yes, though the procedure depends on the controller and the model, and older and newer control platforms use different setup interfaces. Remote monitoring may also offer it, depending on the generator.
