Standby Generator Installation

John from New Providence, NJ has been a Green Sun Energy Services client since September of 2020. The machine is a Generac 7039-1 rated 20 kW on propane and 18 kW on natural gas, running on natural gas, on a 200-amp transfer switch. It was commissioned in May of 2021. A 200-amp whole-house switch on a house of about 2,800 square feet means the panel transfers exactly as it stands. Green Sun has serviced it in May of 2022, July of 2023, August of 2024 and July of 2025, and it is on remote monitoring in between.

Honnie from Ocean, NJ has been a Green Sun Energy Services client since November of 2020. The machine is a Generac 7173 rated 13 kW on natural gas, on a 150-amp transfer switch, and it was commissioned in April of 2021. The house is about 2,079 square feet, which a 13 kW machine carries without difficulty on a whole-house switch. Green Sun has serviced it every year since – March of 2022, March of 2023, February of 2024, January of 2025 and January of 2026 – and it reports to remote monitoring between visits.

Steven from Aberdeen, NJ has been a Green Sun Energy Services client since September of 2020. A Generac Guardian rated 16 kW went in the following July, running on natural gas behind a 200-amp automatic transfer switch, with 1,800 square feet of living space behind it on the load survey. The switch is the decision that matters more than the rating: it is the difference between a generator that runs the house and one that runs a list.

Katia from Colts Neck, NJ has been a Green Sun Energy Services client since October of 2020. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in the following July, running on natural gas behind a 200-amp automatic transfer switch, with 3,600 square feet of living space behind it on the load survey. Nine months between booking and installation is ordinary for a machine this size: the gas work and the township inspection each set their own pace, and the generator waits on both.

Peter from Middletown, NJ has been a Green Sun Energy Services client since August of 2020. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in the following January, running on natural gas behind a 200-amp automatic transfer switch, with 3,200 square feet of living space behind it on the load survey. At 22 kW behind a service-sized switch the machine is not carrying a shortlist of circuits, it is carrying the house – which is what the survey found it needed.

James from Hazlet, NJ has been a Green Sun Energy Services client since March of 2021. A Generac Guardian rated 18 kW on propane and 17 kW on natural gas went in that October, running on natural gas behind a 200-amp automatic transfer switch. The load survey put 1,836 square feet of living space behind it, and the 200-amp switch takes the whole service rather than a selected group of circuits – so an outage changes nothing about how the house is used.

Al from Middletown, NJ has been a Green Sun Energy Services client since June of 2022. A Generac Guardian rated 18 kW on propane and 17 kW on natural gas went in that August, running on natural gas behind a 200-amp automatic transfer switch, with 2,223 square feet of living space behind it on the load survey. The switch is sized to the service rather than to a selected group of circuits, so nothing about the house has to change when the power does.

Milton and Gloria from Middletown, NJ have been Green Sun Energy Services clients since August of 2020. A Generac Guardian rated 20 kW on propane and 18 kW on natural gas went in that November, running on natural gas behind a 200-amp automatic transfer switch, with 2,888 square feet of living space behind it on the load survey. Natural gas is what makes a machine this size practical to live with: nothing to deliver and nothing to monitor, so an outage lasting four days demands no more attention than one lasting four hours.

Christine from Middletown, NJ has been a Green Sun Energy Services client since August of 2020. A Generac Guardian rated 22 kW on propane and 19.5 kW on natural gas went in that October, running on natural gas behind a 200-amp automatic transfer switch. The load survey put 5,000 square feet of living space behind it, which is what puts the machine at the top of the air-cooled range rather than in the middle of it – and with the switch sized to the whole service, an outage takes nothing off the table.

William from Toms River, NJ has been a Green Sun Energy Services client since September of 2023. A Generac Guardian rated 18 kW on propane and 17 kW on natural gas went in that November, running on natural gas, behind a 100-amp automatic transfer switch. The load survey put 1,351 square feet of living space behind it, and the switch is sized to the service rather than to a handful of selected circuits – so when the street goes dark nothing has to be chosen, and the house comes back on its own within seconds.
