Joe from Martinsville, NJ has been a Green Sun Energy Services client since September of 2013, when we installed a 20 kW Generac covering 3,000 square feet with two refrigerators, an electric oven, a dishwasher and the laundry. Seven years later, in the spring of 2020, we replaced that machine with a new one and put it on a PowerBase plan. A generator that reaches the end of its life having done its job is the ordinary outcome, and replacing it is the easy part. Martinsville is in Somerset County.

Standby generator questions from Martinsville homeowners
What size standby generator does a Martinsville home need?
The correct size is decided by the electrical loads the generator is expected to run, not by the square footage of the house. Central air, heat pumps, electric heat, well and sump pumps, refrigerators and freezers, electric ranges and dryers, pool equipment and EV chargers all count. Where a load is connected automatically, the generator either has the capacity for it or an approved load-management system controls it.
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.
Does a generator keep the well running during an outage in Martinsville?
Yes, when the well pump is included in the design. A private well pump is electric, so without power there is no running water at all -- a different order of problem from losing the lights. Homes on a well are among the clearest cases for standby power, and the pump belongs on the load list from the start.
