Barbara from Mantoloking, NJ has been a Green Sun Energy Services client since September of 2023. The generator was commissioned in February of 2024: 18 kW on natural gas, on a 150-amp service-entrance switch with two load management modules. The load calculation asked for 14 kW across the 2,344 square foot house, carrying two sump pumps, two refrigerators, a washer and a gas dryer. Mantoloking is a strip of sand between the ocean and Barnegat Bay, and it is where a generator earns its keep – this is the stretch of coast that loses power first in a storm and gets it back last, with the sump pumps needed at exactly the moment the grid stops. One condition preceded the work: the window nearest the generator was converted to a fixed, non-opening pane, so exhaust can never enter the house. The generator is supported by annual maintenance, a ten-year extended parts-and-labor warranty, and monitoring we manage.

Standby generator questions from Mantoloking homeowners
Does new gas piping have to be pressure tested in Mantoloking?
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 quickly does it take over?
The automatic start sequence normally begins within seconds of the controller deciding that utility power has failed or fallen outside acceptable limits. There is a deliberate short delay so that a momentary flicker does not trigger a full start and transfer. Exact timing depends on the controller, the transfer switch and the configuration.
What is the difference between essential circuits and whole-house backup?
An essential-circuits system transfers a defined set of circuits through a smaller transfer switch rather than the whole electrical service. It is a deliberate design rather than a lesser one: the circuits that matter during an outage are chosen in advance, and the generator only ever has to carry those.
