Nancy from Middletown, NJ has been a Green Sun Energy Services client since February of 2021. The generator was commissioned that November: 18 kW on natural gas, feeding a 200-amp GenReady load center with a smart management module. A GenReady panel replaces the main service panel outright rather than sitting alongside it, so the transfer switch and the breakers are one unit – fewer boxes on the wall and a shorter run between them. The calculation asked for 13 kW across the 2,500 square foot house. One limit was set out in advance: a generator can only surge to within a few amps of the locked rotor current an air conditioner needs to start, so the household was told before the work what the machine would and would not carry at the moment of starting. Annual maintenance, an extended parts-and-labor warranty and monitoring we manage sit behind it.

Standby generator questions from Middletown homeowners
What is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
Does new gas piping have to be pressure tested in Middletown?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
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.
