Gavin from Middletown, NJ has been a Green Sun Energy Services client since June of 2024. The generator was commissioned that August: a 24 kW machine on natural gas, on a 150-amp service-entrance switch with two smart management modules and surge protection. The load calculation asked for 14 kW across the 2,600 square foot house, so the machine carries a wide margin – and the pair of pumps is the reason that margin is worth paying for. A well pump and a sump pump together mean no water coming into the house and no way to move it out once the power stops, and both have to start against their own resistance rather than easing into the load. The generator is supported by annual maintenance, an extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Middletown homeowners
Can the existing natural-gas service in a Middletown home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
What does the kW number on a generator mean?
It is the maximum continuous output the machine is rated to produce under the manufacturer's specified conditions. A current 22 kW model, for example, is rated 22 kW on liquid propane and 21 kW on natural gas. That difference is exactly why the fuel and the model both matter when a generator is sized.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
