Randi from Florham Park, NJ has been a Green Sun Energy Services client since September of 2014, which makes this one of the oldest relationships on the site. The generator was commissioned that December: 20 kW in a steel enclosure on natural gas, on a 200-amp service-entrance switch with two priority management modules. The load calculation asked for 18 kW across 4,000 square feet, with three refrigerators, an electric oven, a washer and a gas dryer to carry. Twelve years is long enough for a standby generator to have been forgotten twice over, and the reason this one has not is the interval: an annual maintenance plan and a ten-year extended parts-and-labor warranty have sat behind it since the machine was new.

Very happy I chose Green Sun Energy 7 years ago for my generator and continued annual service. They are a pleasure to deal with.
Green Sun Energy Services replied
Thank you, Randi. The 20 kW generator at your home in Florham Park went in back in 2014 and has been on annual service ever since, which is exactly the arrangement we would recommend to anyone buying one. A pleasure to deal with is a nice thing to be told after that many visits.
Standby generator questions from Florham Park homeowners
Does new gas piping have to be pressure tested in Florham Park?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
What does a whole-house generator actually mean?
Whole-house generally means the transfer equipment serves the home's main electrical system rather than a small emergency-circuit panel. It does not promise unlimited capacity. High-demand appliances may still be prioritized or briefly shed while generator capacity is being used elsewhere.
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.
