Gerry from Allentown, NJ has been a Green Sun Energy Services client since October of 2021. The generator was commissioned in January of 2022: a Generac Guardian rated 19.5 kW on natural gas, on a 150-amp managed whole-house switch with a smart management module, sized against a 15 kW calculation for the 3,422 square foot house. The contract said plainly what the wait would be: 22 kW generators were running eighteen to twenty-two weeks from signature to installation. Putting the lead time in writing at the point of sale is unusual and worth more than an optimistic verbal estimate – a household that knows it will be four or five months can plan around it, and nobody has to chase an answer that was never given. A sump pump, two refrigerators, a washer, a gas dryer and a dishwasher make up the load.

Standby generator questions from Allentown homeowners
Does a generator keep the well running during an outage in Allentown?
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.
How can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
Can the generator stay connected during a pressure test?
The machine has to be protected from test pressures beyond what its fuel controls are built to withstand. The fuel-gas code sets out when appliances are disconnected or isolated for testing, and the plumbing contractor follows both that code and the generator's installation instructions.
