Ania from Cranbury, NJ has been a Green Sun Energy Services client since May of 2026. The generator was installed by another company and commissioned in July of 2020, and the servicing came to us nearly six years later, beginning with the six-year service that May. Six years is the point at which a standby generator has outlived its original warranty and whatever attention came with it, and the question becomes simply whether anybody is still opening the enclosure once a year. An annual maintenance plan now covers the yearly visit.

Standby generator questions from Cranbury homeowners
What size standby generator does a Cranbury home need?
The correct size is decided by the electrical loads the generator is expected to run, not by the square footage of the house. Central air, heat pumps, electric heat, well and sump pumps, refrigerators and freezers, electric ranges and dryers, pool equipment and EV chargers all count. Where a load is connected automatically, the generator either has the capacity for it or an approved load-management system controls it.
Do underground utilities have to be marked before the trench is dug?
Yes. Underground facilities must be addressed through the New Jersey One Call process before the excavation begins, which is what protects buried gas, electric, telecommunications and water lines from being struck.
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.
