Cathy from Red Bank, NJ has been a Green Sun Energy Services client since December of 2019. The machine is a Generac 7043-2 rated 22 kW on propane and 19.5 kW on natural gas, running on natural gas, on a 200-amp transfer switch, and it was commissioned in March of 2020. At about 5,500 square feet this is one of the largest houses in the portfolio on a 22 kW machine, and it is where the load calculation stops being a formality – what matters is not the floor area but how much of it runs at once. Green Sun has serviced it six times since, most recently in December of 2025, and it reports to remote monitoring in between.

The scheduling and installation of my full house generator by Green Sun Energy was flawless and almost immediately proved to be invaluable with a 4 day blackout. Glen, Karen and their team could not have been more professional, informative and punctual. After consulting with a few other companies I'm convinced I made the right choice going with Green Sun Energy. I highly recommend them and know you will not be disappointed.
Standby generator questions from Red Bank homeowners
Does the residential building code apply to a generator?
It can. For applicable one- and two-family dwellings New Jersey adopts the 2024 International Residential Code, subject to state amendments. Structural and flood-related generator installations may therefore need review under the residential subcode as well as the electrical and fuel requirements.
Can a standby generator run central air conditioning?
Yes, when it is sized for it. The design has to account for both the running demand and the starting surge of the air-conditioning equipment. Load-management equipment can be used where necessary so that demand does not all arrive at once.
How is the gas pipe size worked out?
From the generator's demand, the available pressure, the pipe length, the allowable pressure drop, the fittings, the pipe material and every other appliance connected to the system. The adopted fuel-gas code carries the sizing requirements and tables, and the model's published fuel consumption goes into the calculation.
