Amy from Morristown, NJ has been a Green Sun Energy Services client since April of 2024. The generator was commissioned in June: a 10 kW machine on natural gas, feeding a ten-circuit indoor transfer switch rather than the whole house, sized against a 13 kW calculation for the 2,000 square foot home. Essential circuits is the approach that suits a household happy to decide in advance what matters – the sump pump, the refrigerator, the heating – rather than paying for capacity to run everything at once. Shelves on the wall beside the electrical panel had to come down before the work, which is the kind of thing better agreed in the quotation than discovered by an electrician holding a transfer switch. Annual maintenance, a seven-year extended parts-and-labor warranty and monitoring we manage all sit behind the machine.
Why Amy chose Green Sun Energy Services
Complete backup power, from sizing and installation to the service that keeps it ready.

Standby generator questions from Morristown homeowners
What gas pressure does a generator need?
It is model-specific and has to be read off the specification sheet rather than assumed. A current 22 kW model, for instance, specifies a minimum natural-gas pressure of 3.5 inches water column. Different models carry different requirements.
Can a generator be sized from the square footage of the house?
No. Two houses of identical size can have very different electrical requirements depending on heating fuel, how many air conditioners there are, whether there is a well pump, a pool, an EV charger, or electric cooking. A proper design examines the load rather than the floor area.
How far from the property line does a generator need to be in Morristown?
There is no single statewide New Jersey property-line setback for a residential generator. Setbacks are set by the municipality's zoning ordinance, so the requirement is a Morristown question rather than a general one. A generator can meet every manufacturer clearance and still breach a side-yard or rear-yard setback, which is why the zoning review happens before the location is fixed.
