Richard from Long Branch, NJ has been a Green Sun Energy Services client since November of 2020. The machine is a Generac 7210 rated 24 kW on propane and 21 kW on natural gas, running on natural gas, on a 200-amp transfer switch, and it was commissioned in June of 2021. At about 3,400 square feet with the whole panel transferring, 24 kW is the size the load calculation lands on once central air is counted rather than assumed away. Green Sun has kept it on scheduled maintenance ever since – June of 2022, May of 2023, May of 2024, March of 2025 and March of 2026 – and it reports to remote monitoring in between.

Standby generator questions from Long Branch homeowners
Does new gas piping have to be pressure tested in Long Branch?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
How can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
Does the house run on the generator during its weekly exercise?
Not necessarily -- it depends on the generation of equipment, the controller and the configuration. Traditional systems commonly exercise without transferring the house at all. Newer equipment with current controls may support different exercise and transfer behaviour.
