16 kW Generac standby generator in Little Egg Harbor, NJ by Green Sun Energy Services.
John and Charlotte Stewart have been Green Sun Energy Services clients since March of 2016, when they bought a solar array and a standby generator in the same conversation. The two installations finished a day apart at the end of May.
24 panels and 7.2 kW
Twenty-four LG 300 watt panels came to 7.2 kW on QuickMount flashed mounts, with a SolarEdge SE6000A inverter and a power optimizer on every panel. An optimizer handles each panel’s output on its own, so one shaded or underperforming panel does not set the pace for the rest of the string. Atlantic City Electric is the utility and the first year was estimated at 9,795 kWh. The array was finished on 26 May 2016.
A 16 kW standby, sized by the load calculation
The house is about 1,600 square feet on a 200-amp service. Run through NEC Article 220 Part IV, the connected load came to 21,028 watts, of which heating and cooling account for 6,000. Load management sheds that 6,000 while the generator is carrying the house, which brings what the machine actually has to meet down to 9,028 watts against a 9 kW minimum. The 16 kW Generac in an aluminum enclosure covers it with margin, and it runs on natural gas, so there is no tank to keep an eye on. The transfer switch is a 200-amp service-entrance type mounted outdoors beside the meter, which keeps the whole house behind one switch rather than splitting the panel into essential circuits. It was finished on 27 May 2016 and we were back to service it in April 2026.
A day apart, and two different jobs
Solar and standby power are bought together often enough that they get described as one purchase. They are not. The array works when the sun is up and the grid is up, and it changes what the house draws from Atlantic City Electric across the year. The generator does nothing at all until the grid fails, and then it carries the house. Buying both in one conversation, as this household did, means one design, one permit set, one inspection schedule, and one company answering for both of them afterwards.
Glen and Green Sun Energy were great. For example, they moved vents on my roof to have an even pattern for the solar panels. They replaced large river rock around the Generator stand when they got buried. Everything was well managed and I can’t recommend them enough.
Green Sun Energy Services replied
John, thank you for taking the time to share this. Glen will be glad to hear the feedback, and it's great to know that the details — moving the roof vents for a clean panel layout and resetting the river rock around the generator stand — made a difference. We appreciate you trusting us with the project.

Questions from Little Egg Harbor homeowners
Standby generatorCan a standby generator run central air conditioning?
Yes, when it is sized for it. The design has to account for both the running demand and the starting surge of the air-conditioning equipment. Load-management equipment can be used where necessary so that demand does not all arrive at once.
Standby generatorCan the exercise time be changed?
Yes, though the procedure depends on the controller and the model, and older and newer control platforms use different setup interfaces. Remote monitoring may also offer it, depending on the generator.
Standby generatorCan a generator be installed in a flood zone in Little Egg Harbor?
Yes, but the generator and its electrical equipment may need to be elevated or otherwise protected. The installation is evaluated against the property's FEMA flood zone, its Base Flood Elevation and Design Flood Elevation, the municipal flood ordinance, any applicable freeboard, and NJDEP requirements where they apply. It is a property-by-property assessment rather than a rule of thumb.
SolarHow does residential solar work on a Little Egg Harbor home?
The panels convert sunlight into direct-current electricity, and an inverter or microinverters convert that into alternating current the house can use. When the array produces more than the house is drawing, the surplus flows out through the utility meter under New Jersey's net-metering rules. When the house needs more than the array is making, the difference comes from the utility.
SolarCan the system be switched on before the utility approves it?
A grid-connected system should not be placed into normal parallel operation until the utility has issued the required authorisation. Running it beforehand can breach the interconnection agreement and the utility's requirements.
