Sakeer from Manalapan, NJ has been a Green Sun Energy Services client since March of 2024. The Generac 6250 at the house is a 20 kW machine on propane and 18 kW on natural gas, running on natural gas, feeding a 90-amp transfer switch. It was installed in October of 2014 by another company. Green Sun took it on in March of 2024, returned that April, and has serviced it each March since – 2025 and 2026. A machine that has been running for a decade earns a proper look once a year: the wear is gradual, and none of it announces itself until the power goes.

Standby generator questions from Manalapan homeowners
How close to the house can a generator sit in Manalapan?
For the air-cooled models covered by the manufacturer's listed installation guidance, the rear of the generator can be as close as eighteen inches to a qualifying structure when every condition of that listing is met. That eighteen inches is a tested installation dimension, not a zoning setback, and a municipality can require more.
Should gas pressure be checked while the generator is running?
Yes. Operating pressure means more than a static reading taken with the generator off. The fuel system has to hold adequate pressure while the generator runs and other appliances may also be drawing gas. That matters most when an existing residential service is being reused.
Can the generator run the propane tank right down?
It is a poor outage plan. Propane should be monitored and topped up before the generator runs out. Usable capacity is not the same as the tank's nominal water capacity, and cold weather reduces how much vapour the tank can deliver just when the machine is working hardest.
