William from Morganville, NJ has been a Green Sun Energy Services client since October of 2021. The generator was commissioned the following January, rated 19.5 kW on natural gas, and the load calculation had asked for 19 kW – high for a house of 3,026 square feet. The electric dryer and electric oven are the reason: both draw several times what their gas equivalents do, and a load survey counts what is actually in the house rather than its floor area. Two sump pumps and the cold storage sit on the same machine, whole-house on a 200-amp service.

Standby generator questions from Morganville homeowners
What is Base Flood Elevation and why does it matter here?
Base Flood Elevation is the elevation associated with the base flood -- generally the flood with a one percent chance of being reached or exceeded in any year. For a generator it is often the starting point for working out how high the mechanical and electrical equipment has to be protected or raised.
Will a larger gas meter be needed?
Possibly. A generator can significantly increase a home's maximum gas demand. If the existing meter or service cannot hold the required pressure while supplying the generator and the other appliances together, the gas utility may require an upgrade.
Will a 22 kW generator run an entire Morganville house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
