A generator sits quietly for a year and then has to work on the one night it matters. That means the battery, the oil, the weekly test cycle and the transfer switch, all checked before the storm rather than during it. These are New Jersey homes we look after on a maintenance plan, and plenty of the generators on this list were installed by somebody else. Each one names the equipment on site and the town, so what you are reading is work we actually did rather than a list of what a plan covers.

939 completed generator service projects across 142 New Jersey towns, including 165 with a review written by the customer.

20 kW Standby Generator Installation in Shrewsbury, NJ | Whole-House Backup

Riccardo from Shrewsbury, NJ has been a Green Sun Energy Services client since September of 2019. The generator was commissioned that December: 20 kW on natural gas, on a 200-amp whole-house transfer switch, sized against a 17 kW calculation for the 3,800 square foot house. A sump pump, two refrigerators, a separate freezer, a washer, a gas dryer and a dishwasher make up the load. Whole-house rather than a critical-load panel is the choice worth noting on a house this size: nothing has to be nominated in advance as the part that keeps working. An annual maintenance plan covers the

Standby Generator Installation in Interlaken, NJ | Essential Circuits Backup

Brian from Interlaken, NJ has been a Green Sun Energy Services client since November of 2019. The generator was commissioned in March of 2020, and it is an essential-circuits installation rather than whole-house: named circuits carried through an outdoor-rated transfer switch, sized against a 13 kW calculation for the 2,526 square foot house. The air conditioning was deliberately placed at a lower priority than everything else in the switch, which is the honest trade a household makes on this approach – the sump pump, the refrigerators and the freezer come first, and cooling waits its turn. Deciding that in advance

Standby Generator Service in Keansburg, NJ | Six Straight Years of Generator Service

Brian from Keansburg, NJ has been a Green Sun Energy Services client since May of 2020. The generator was installed by another company and commissioned in April of 2015, and the servicing came to us five years later. It has been seen every spring since – May of 2020, April of 2021, March of 2022, March of 2023, June of 2024 and September of 2025 – working from the five-year service up to the ten-year interval it now repeats. Keansburg sits directly on the bay, where salt in the air works on anything left outdoors, so the yearly look inside

18 kW Standby Generator Installation in Allenhurst, NJ | Whole-House Backup

Lara from Allenhurst, NJ has been a Green Sun Energy Services client since June of 2025. The generator was commissioned in July: 18 kW on natural gas, on a 200-amp service-entrance switch with two load management modules and surge protection. The load calculation asked for 14 kW across the 2,700 square foot house, so the machine sits comfortably above what the code requires. Allenhurst is a single square mile on the ocean, and the surge protection matters as much as the generator itself here – power coming back after a coastal storm is rarely clean, and the moment the grid

Standby Generator Service in Farmingdale, NJ | Servicing Taken Over

Edward from Farmingdale, NJ has been a Green Sun Energy Services client since June of 2025. The generator was installed by another company and commissioned in March of 2021, and the servicing moved to us four years later. The first visit was the four-year service in July of 2025, and the five-year service followed in July of 2026. Four years is roughly where a standby generator stops being new – the break-in oil is long gone, the battery is entering the range where it starts letting people down, and the plugs and filters have real hours on them. An annual

20 kW Standby Generator Installation in Red Bank, NJ | Generac Generator

Jim from Red Bank, NJ has been a Green Sun Energy Services client since September of 2013, which makes this one of the longest relationships on the site. The generator was commissioned that October: 20 kW on natural gas, on a 200-amp whole-house transfer switch with two priority management modules. The load survey is unlike any other we have written up – four well pumps, alongside a sump pump, two refrigerators, a separate freezer, an electric oven, a washer and a gas dryer. Four pumps on one property means water is being moved rather than merely supplied, and none of

Standby Generator Service in Middletown, NJ | Servicing Taken Over

Kristin from Middletown, NJ has been a Green Sun Energy Services client since December of 2025. The generator was installed by another company and commissioned in December of 2021, and the servicing moved to us four years later, beginning with the four-year service that same month. Four years is roughly the point at which a standby generator stops being new: the break-in oil is long gone, the battery is entering the range where it starts letting people down, and the plugs and filters have real hours on them. Picking a machine up at that stage means the record starts before

Standby Generator Service in Morganville, NJ | Taking Over a Generator Installed by Another Company

Thomas from Morganville, NJ has been a Green Sun Energy Services client since September of 2021. The generator was installed by another company and commissioned in November of 2018, and the servicing came to us three years later. We ran the three-year service that September and the four-year service in October of the following year. This is call-when-needed servicing rather than a scheduled plan – the visit is arranged when the household wants it, and each one is agreed and billed on its own. It suits an owner who would rather decide year by year than commit in advance, and

18 kW Standby Generator Installation in Mantoloking, NJ | Backup on the Barrier Island

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

Generator Service in Oceanport, NJ | Client Since 2021

James from Oceanport, NJ has been a Green Sun Energy Services client since October of 2021. The generator was installed by another company and commissioned in February of 2021, and the servicing came to us eight months later, beginning with a startup inspection on a machine we had not put in. It has been seen every winter since – January of 2022, January of 2023, February of 2024 and January of 2025 – working from the first-year service up to the four-year, 600-hour one. The first visit found a slow oil seep that could not be traced to a single

Standby Generator Service in Pt Pleasant Beach, NJ | On the Point Pleasant Oceanfront, Client Since 2020

Connie from Point Pleasant Beach, NJ has been a Green Sun Energy Services client since October of 2020. The generator was installed by another company and commissioned in January of 2020, and the servicing came to us nine months later, along with cellular monitoring and an extended warranty. It has been seen every winter since – March of 2022, March of 2023, April of 2024, February of 2025 and February of 2026 – and three separate repairs have been handled in that time, two under the manufacturer’s warranty and one under workmanship cover. A machine standing on the oceanfront takes

13 kW Standby Generator Installation in Red Bank, NJ | Whole-House Backup

Shari from Red Bank, NJ has been a Green Sun Energy Services client since August of 2020. The generator was commissioned in April of 2021: a 13 kW Generac Guardian on natural gas, on a 150-amp service-entrance switch with two smart management modules. The load calculation asked for 14 kW across the 1,536 square foot house, and the two management modules are what let a 13 kW machine cover it – they hold back the heaviest draw for a moment when several things start together, rather than dividing the house into circuits that matter and circuits that do not. One
