Miguel from Middletown, NJ has been a Green Sun Energy Services client since November of 2022. The generator was commissioned in January: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp managed whole-house switch with surge protection, sized against a 17 kW calculation for the 3,000 square foot house. Three sump pumps is the most on any survey on the site, and a house with three has settled the question of whether it needs backup power. One condition was agreed before the work: the household would seal the basement window where the generator was to sit. A generator has to stand a set distance from any openable window, because exhaust finds its way into a house through whichever opening is nearest – and where the distance cannot be met, the opening has to stop being one.

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.
How does the starting battery stay charged?
The system includes battery-charging provisions so the starting battery stays ready while the generator waits for an outage. A charging fault, a blown fuse, a wiring problem or simply a tired battery can stop a generator starting when it is needed, which is why battery condition is part of routine maintenance rather than an afterthought.
Can a generator go under a deck?
Only if the specific installation satisfies every requirement for overhead clearance, airflow, exhaust, fire separation, carbon-monoxide safety and service access. Because the applicable guidance commonly requires substantial overhead clearance, many ordinary under-deck locations will not qualify. It is a site-specific review rather than a standard placement.
