Alexandria from Aberdeen, NJ has been a Green Sun Energy Services client since January of 2021. The generator was commissioned in July of 2022: 17 kW on natural gas, on a 200-amp managed whole-house switch with a smart management module and surge protection, sized against a 13 kW calculation for the 1,900 square foot house. Two refrigerators, a separate freezer, a washer, a gas dryer and a dishwasher make up the load, so the machine carries a comfortable margin over what the calculation required. Sixteen months separated the contract from the commissioning, which was the shape of generator work through that period – permits, utility scheduling and equipment lead times all ran in sequence rather than together. Servicing is arranged as and when rather than on a schedule.

Standby generator questions from Aberdeen homeowners
What happens if the manufacturer and Aberdeen disagree?
The installation has to satisfy all applicable requirements. A manufacturer's listing cannot be ignored, and a manufacturer's minimum clearance does not cancel a municipal zoning requirement. Where requirements conflict or the interpretation is uncertain, the Authority Having Jurisdiction is consulted before the work goes in rather than after.
What actually gets done at a service visit?
It depends on the model, the age and the interval, but typically engine oil and filter, air filter, spark plug inspection or replacement, battery inspection, a fuel-system leak check, sediment-trap inspection, valve clearance where applicable, and inspection of the enclosure and intakes.
What is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
