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.

22 kW Standby Generator Installation in Holmdel, NJ | Whole-House Backup

Nancy from Holmdel, NJ has been a Green Sun Energy Services client since June of 2024. The generator was commissioned that October: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with a smart management module and surge protection. The load calculation asked for 13 kW across the 2,400 square foot house, so the machine installed carries a wide margin over the code minimum – which is the difference between a generator that runs near its limit whenever it is called on and one that idles comfortably through the same outage. The generator is supported

17 kW Standby Generator Installation in Little Egg Harbor, NJ | Whole-House Backup

Dorothy from Little Egg Harbor, NJ has been a Green Sun Energy Services client since July of 2021. The generator was commissioned that December: a Generac Guardian rated 17 kW on natural gas, on a 200-amp whole-house transfer switch, sized against a 14 kW calculation for the 2,300 square foot house. Little Egg Harbor sits at the top of the bay behind Long Beach Island, and the storms that reach it arrive with the whole Atlantic behind them – which is why whole-house coverage made more sense here than nominating a handful of circuits to keep alive. Two refrigerators, a

Standby Generator Service in Skillman, NJ | Two Generator Services

Santi from Skillman, NJ has been a Green Sun Energy Services client since August of 2020. The generator was installed by another company and commissioned in January of 2015, and the servicing came to us five years later. We ran the first-year service in August of 2020 and the two-year service in October of 2021. The interval names track running hours rather than the calendar, which is why a machine five years old was still due its early-interval work – a standby generator that has rarely been called on accumulates hours very slowly, and the schedule follows the hours rather

Standby Generator Service in Middletown, NJ | Servicing Taken Over

Mary Ellen from Middletown, NJ has been a Green Sun Energy Services client since February of 2025. The generator was installed by another company and commissioned in May of 2013, and the servicing came to us nearly twelve years later. The first visit was a startup inspection – the assessment we run on any machine we did not install, establishing hours, condition and what has actually been done to it before committing to a schedule. The ten-year service followed in February of 2026. On a generator entering its second decade that first look matters more than the interval it happens

Standby Generator Service and Solar Panel Installation in Matawan, NJ | Backup First, Then 34 Panels

Susan in Matawan has been a Green Sun Energy Services client since March of 2022, when the standby generator on this property came onto our books. The solar array followed three and a half years later. The generator, on our books since 2022: The machine is a Generac 22 kW from the 7000 series, model 70432, installed by another company. Its servicing came to us in March 2022 on a PowerBase Diamond plan with Wi-Fi monitoring, and it was last serviced on 26 August 2026. Diamond with monitoring is the arrangement that suits a machine somebody else installed. There is

Standby Generator Installation and EV Charger Installation in Manansquan, NJ | A 16 kW Generator in 2021, an EV Charger in 2025

Peter from Manasquan, NJ has been a Green Sun Energy Services client since August of 2020. The generator went in that winter; the car charger followed nearly five years later. A 16 kW Generac on a managed whole-house switch: Commissioned on 6 January 2021. The calculation asked for a minimum of 15 kW under NEC Article 220 Part IV and a 16 kW Generac Guardian went in on natural gas, behind a 200-amp managed whole-house transfer switch with two smart management modules. The house is 3,000 square feet with two refrigerators, a dishwasher, a washer, a gas dryer and a

21 kW Standby Generator Installation in Bridgewater, NJ | Whole-House Backup

Christopher from Bridgewater, NJ has been a Green Sun Energy Services client since February of 2024. The generator was commissioned that May: a Generac Guardian rated 21 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules and surge protection. The load calculation asked for 16 kW across 3,000 square feet, carrying a well pump, a sump pump, a heat pump, two refrigerators, a washer, a gas dryer and a dishwasher. A well and a sump on the same property is the combination that makes backup power less about comfort than about the house continuing to

21 kW Standby Generator Installation in Lincroft, NJ | Across Two Service Panels

Randal from Lincroft, NJ has been a Green Sun Energy Services client since May of 2021. The generator was commissioned in February of 2022: a Generac Guardian rated 21 kW on natural gas, feeding two 200-amp transfer switches with three smart management modules between them. Two service panels is what a 5,500 square foot house tends to end up with, and it changes the job – each panel needs its own switch, and the load management has to work across both so the machine is never asked for more than it can give. The calculation asked for 21 kW, carrying

16 kW Standby Generator Installation in Brick, NJ | Backup for a Lakeside Home

Scott from Brick, NJ has been a Green Sun Energy Services client since September of 2020. The generator was commissioned in June of 2021: a 16 kW Generac Guardian on natural gas, outdoors beside the meter, with a 150-amp service-entrance switch and two smart management modules. The load calculation asked for 12 kW, and what has to keep running says more than the number does – two refrigerators, a separate freezer, a sump pump, a washer, a gas dryer and a dishwasher. The sump and the cold storage are the pair that matter most: one is needed exactly when a

Standby Generator Service in Colts Neck, NJ | Three Generator Services

Charles from Colts Neck, NJ has been a Green Sun Energy Services client since January of 2020. The generator was installed by another company and commissioned in November of 2011, and the servicing came to us eight years later. We ran the five-year service in January of 2020, the six-year service in January of 2021 and the seven-year service that December. The interval names lag the calendar on a machine like this because they track running hours rather than birthdays – a generator that has spent a decade waiting quietly for an outage has far fewer hours on it than

17 kW Standby Generator Installation in Colonia, NJ | Whole-House Backup

Michael from Colonia, NJ has been a Green Sun Energy Services client since February of 2022. The generator was commissioned that May: a Generac Guardian rated 17 kW on natural gas, outdoors beside the meter, with a 200-amp service-entrance switch, a smart management module and surge protection. The load calculation asked for 14 kW across 1,508 square feet, with an electric dryer among the loads – the item that most often pushes a small house past what its size would suggest, since an electric dryer draws roughly five times what a gas one does. The generator is supported by annual

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

Ryan from Red Bank, NJ has been a Green Sun Energy Services client since December of 2019. The generator was commissioned in March of 2020: a 16 kW Generac Guardian on natural gas, outdoors beside the meter, on a 200-amp whole-house transfer switch. The load calculation asked for 14 kW across the 2,106 square foot house, with two refrigerators, a washer, a gas dryer and a dishwasher to carry, so the machine sits above the requirement rather than at it. Whole-house rather than a critical load panel is the choice worth noting – nothing in the house has to be
