Peggy from Farmingdale, NJ has been a Green Sun Energy Services client since June of 2019. The 20 kW standby generator at the house was installed by another company in January of 2013, and Peggy moved its servicing to us six years later. Every interval since has been carried out without a gap — the six-year service onward, with the most recent completed in February of 2026 at 91.9 hours on the meter and the fuel plenum inspected and clear of rust — along with several service calls when the machine needed attention between visits. The generator remains under one of our annual service plans, and it runs a managed whole-house switch, so nothing in the house is left on utility power once it starts.

Standby generator questions from Farmingdale homeowners
What happens if the manufacturer and Farmingdale disagree?
The installation has to satisfy all applicable requirements. A manufacturer's listing cannot be ignored, and a manufacturer's minimum clearance does not cancel a municipal zoning requirement. Where requirements conflict or the interpretation is uncertain, the Authority Having Jurisdiction is consulted before the work goes in rather than after.
Why is an eighteen-inch wall clearance allowed?
Because it comes from the manufacturer's tested and listed installation configuration. Applicable units are listed and labelled for installation as close as eighteen inches to a structure, subject to openings and local requirements. New Jersey adopts the National Electrical Code, which requires listed equipment to be installed in accordance with the instructions attached to that listing -- so the eighteen inches is a tested dimension, not a rule of thumb.
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.
