Kevin from Rumson, NJ has been a Green Sun Energy Services client since September of 2020. The 22 kW Generac at the house dates from March of 2019 and runs on natural gas behind a 100-amp transfer switch. Green Sun serviced it every year from 2021 through 2024 on a plan that covered annual maintenance and remote monitoring, and fitted a new battery in July of 2022. The monitoring was set up in November of 2021, which is how a fault gets noticed before the next storm rather than during it.

Standby generator questions from Rumson homeowners
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.
Does a generator in Rumson have to sit twelve inches above the flood elevation?
That figure should not be treated as a universal rule without looking at the actual property. The required elevation can depend on the flood-zone designation, the municipal freeboard, the Design Flood Elevation, Coastal A or V Zone conditions, NJDEP requirements and the applicable building-code provisions. Each flood-zone installation is worked out individually.
What happens when the utility power comes back?
The system detects the return of acceptable utility power and transfers the house back automatically. The generator then runs through a programmed cool-down before shutting off and returning to standby. Nobody has to switch anything back by hand.
