Glenn from Farmingdale, NJ has been a Green Sun Energy Services client since October of 2020. The generator was commissioned in June of 2021: a Generac Guardian rated 19.5 kW on natural gas, with a 200-amp service disconnect, a bisque trim kit and the transfer switch mounted in the garage. The load calculation asked for 18 kW across the 2,758 square foot house, and the double electric oven is a good part of the reason – two ovens running together draw more than most of the rest of a kitchen combined. Two refrigerators, a washer, a gas dryer and a dishwasher fill out the list. An annual maintenance visit keeps it serviced.

Standby generator questions from Farmingdale homeowners
Does a generator in Farmingdale 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 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.
What fuel does a home standby generator use?
Most residential air-cooled standby generators are designed to run on either natural gas or vapour-withdrawn liquid propane. The generator and its fuel system have to be configured for whichever is chosen, and the required pressure, capacity and consumption figures depend on the model.
