Susan from Middletown, NJ has been a Green Sun Energy Services client since September of 2021. The generator was commissioned in January of 2022: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules. The load calculation asked for 13 kW across the 2,066 square foot house, and the machine sits well above it – two heat pumps are the reason, since each draws several times its running load in the instant the compressor starts, and two starting together is the moment that decides whether a generator copes. The two management modules exist to make sure they never do start together. A sump pump, two refrigerators, a washer, a gas dryer and a dishwasher complete the load.

Standby generator questions from Middletown homeowners
Do generator requirements in Middletown differ from the next town over?
The manufacturer's equipment requirements do not change when you cross a municipal boundary into Middletown, but local zoning can. A township may impose its own side-yard and rear-yard setbacks, mechanical-equipment rules, screening, noise requirements and floodplain provisions. That is why every property gets a municipal zoning review rather than a general answer.
What happens if we add a heat pump, a pool or an EV charger later?
Any major new electrical load should prompt a review of the generator's capacity. A machine sized correctly at installation may no longer be adequate once substantial loads are added. Load management can often accommodate the new equipment without replacing the generator.
What does a standby generator sit on?
A stable, level support system allowed by the model's installation instructions. Depending on the machine and the site that can be an approved composite base, a prepared aggregate base, a concrete pad, or an engineered elevated platform.
