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 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Most residential air-cooled standby generators are designed to run on either natural gas or vapour-withdrawn liquid propane.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.
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.
