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.

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

200-amp automatic transfer switch in Clark, NJ

Generac 22 kW Standby Generator in Clark, NJ | Surge Protection and Load Management

Nick from Clark, NJ has been a Green Sun Energy Services client since February of 2022. He signed in mid February and the generator was commissioned at the end of July, a 22 kW Generac on its own pad with a 200-amp service-rated transfer switch, a whole-house surge protective device and two management modules so the heavy loads take turns rather than compete. A Generac service contract has covered it since, with scheduled maintenance and monitoring. Clark is in Union County, at the northern end of where our generator crews work.

11 kW Generac standby generator in Belford, NJ

Standby Generator Service in Belford, NJ | Generac 11 kW, Decade-Long Coverage

David from Belford, NJ has been a Green Sun Energy Services client since August of 2022. His generator is an 11 kW Generac from the 7032 series, covered by our Gold plan on a ten year term. What Gold buys is predictability: the maintenance visits happen on a schedule somebody else keeps track of, the wear parts are included, and the bill does not arrive as a surprise after a failure. Belford is in Monmouth County, down near the bay, where the ground is flat and the power lines are old.

14 kW Generac standby generator in Middletown, NJ

Standby Generator Service in Middletown, NJ | An Existing Generac Brought Under Cover

Antonia from Middletown, NJ has been a Green Sun Energy Services client since September of 2024. She and Robert brought their standby generator under a Generac service contract that autumn, which is the quiet half of owning backup power: oil and filter changes, battery and transfer switch checks, a load test, and remote monitoring that reports a fault the week it happens rather than the night the lights go out. Middletown is in Monmouth County, and generators here work hard enough that an annual visit is not optional.

Generac 16 kW Standby Generator in Middletown, NJ | 150-Amp Switch with Load Management

Nadine from Middletown, NJ has been a Green Sun Energy Services client since September of 2020. She signed in September and the generator was commissioned the following May, an eight month wait that had everything to do with that year and nothing to do with the job. It is a 16 kW Generac on its own pad with a 150-amp service-rated transfer switch and a management module for the largest load. A Generac service contract has covered it since. Middletown is in Monmouth County.

Standby Generator Service in Farmingdale, New Jersey

Standby Generator Service in Farmingdale, NJ | Generac 16 kW, Wi-Fi Enabled

Don from Farmingdale, NJ has been a Green Sun Energy Services client since April of 2025. His 16 kW Generac from the 7100 series is Wi-Fi enabled and covered by our PowerBase Silver plan. Silver is the straightforward tier: scheduled maintenance visits where the oil and filters are changed, the battery is tested, the transfer switch is checked and the unit is run under load. The Wi-Fi means the generator can flag a problem between those visits. Farmingdale is in Monmouth County, well inside our service radius.

Standby Generator Installation in Belford, NJ | Reliable Backup Power Near the Bay

Michael from Belford, NJ has been a Green Sun Energy Services client since August of 2020, and we completed his Generac standby generator installation in May of 2021. Living close to the bay means coastal storms and nor’easters are a regular fact of life, and the generator starts on its own within seconds of losing utility power — keeping heat, lights, refrigeration and the sump pump running through the worst of it. A Green Sun service plan with scheduled maintenance keeps the unit tested and ready between storms. Homeowners across Monmouth County rely on Green Sun Energy Services for standby

Diamond is the tier we recommend on the newer 7200s, where the monitoring is built in and worth using. Atlantic Highlands is in Monmouth County.

Generac 20 kW Standby Generator in Freehold, NJ | 200-Amp Switch, Two Management Modules

Chris from Freehold, NJ has been a Green Sun Energy Services client since October of 2020. He signed in early October and the generator was commissioned the following June, eight months, which was the shape of that year rather than anything unusual about the job. It is a 20 kW Generac on a pad with a 200-amp service-rated transfer switch and two management modules so the air conditioning and the other large draws do not collide. A Generac service contract has covered it since. Freehold is in Monmouth County.

22 kW Generac standby generator in Middletown, NJ

Generac 22 kW Standby Generator in Middletown, NJ | Surge Protection and Load Management

Doug from Middletown, NJ has been a Green Sun Energy Services client since August of 2025. He signed in late August and the generator was commissioned in early November, a 22 kW Generac on a composite pad behind a 200-amp service-rated transfer switch, with surge protection and two load management modules keeping the biggest draws from arriving at once. A Generac service contract covers the maintenance from here. Middletown is in Monmouth County, where we install more standby power than in any other town.

20 kW Generac standby generator in Holmdel, NJ

Generac Generator Service Plan in Holmdel, NJ | Scheduled Maintenance and Remote Monitoring

Bryan from Holmdel, NJ has been a Green Sun Energy Services client since July of 2019. The work on this account is upkeep rather than installation. A PowerBase service contract puts his standby generator on a scheduled maintenance cycle, so our technicians inspect the unit, run it under load, change oil and filters, and check the transfer switch on a set rhythm. Faults show up during a visit rather than in the middle of an outage, and remote monitoring covers the stretches in between. Holmdel sits in Monmouth County, where we service standby generators through every season.

Standby Generator Service in Rumson, NJ | Scheduled Maintenance for a Shore Home

Dan from Rumson, NJ has been a Green Sun Energy Services client since November of 2022. He came to us for maintenance rather than installation, putting his standby generator under a PowerBase service contract in the autumn of that year. The plan covers scheduled visits where our technicians change the oil and filters, test the battery and transfer switch, and run the unit under load, with remote monitoring watching for faults between appointments. Rumson sits on the Monmouth County shore, where a generator that has not been serviced tends to reveal it at the worst possible moment.

20 kW Generac standby generator in West Windsor, NJ

Standby Generator Service in West Windsor, NJ | Annual Maintenance Since 2018

Satish from West Windsor, NJ has been a Green Sun Energy Services client since September of 2018. What he bought was not equipment but attention: a Generac service contract covering his standby generator. On a set schedule somebody who knows the machine opens it up, changes the oil and filters, checks the battery and the transfer switch, and runs it under load to be certain it will start when the grid does not. West Windsor is in Mercer County, and a generator serviced every year is a different machine from one that has not been touched.
