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 well pump – and the well pump is the entry that changes the argument. A house on a public main loses its lights during an outage. A house on a well loses its water: no taps, no shower, nothing to flush with, from the moment the power stops. A pump is also a motor load that draws a surge every time it starts, so it shapes the sizing as well as the reasoning. The machine has been on our Diamond plan since: annual maintenance, extended parts-and-labor cover and remote monitoring that Green Sun runs directly.
A GM PowerUp charger on a 60-amp circuit
12 November 2025. The household supplied the charger – a GM PowerUp Level 2 unit – and we hardwired it in the garage on a dedicated 60-amp circuit at 11.5 kW, roughly 36 miles of range an hour. Supplying your own hardware is perfectly reasonable, and it makes the wiring the whole job: the circuit, the breaker, and the question of whether the service can carry another large load.
Five years apart, and the number that decided it
With the charger included, the calculated minimum service for this house came to 169.43 amps against a 200-amp panel. Comfortable, but not the kind of comfortable anybody should assume – thirty amps is less headroom than it sounds when a well pump and a car charger can both decide to start at once. The generator is the reason that question was easy to answer in 2025: the service had already been surveyed properly in 2020, every load counted and written down, and the two management modules were already in place to arbitrate between them. A charger added to a house with a standby generator is not simply another circuit. It is a large intermittent load that the machine may one day have to carry alongside the pump that keeps the water running, and it is worth knowing which of the two gives way first.

Questions from Manasquan homeowners
Standby generatorCan the generator stay connected during a pressure test?
The machine has to be protected from test pressures beyond what its fuel controls are built to withstand. The fuel-gas code sets out when appliances are disconnected or isolated for testing, and the plumbing contractor follows both that code and the generator's installation instructions.
Standby generatorHow far from the property line does a generator need to be in Manasquan?
There is no single statewide New Jersey property-line setback for a residential generator. Setbacks are set by the municipality's zoning ordinance, so the requirement is a Manasquan question rather than a general one. A generator can meet every manufacturer clearance and still breach a side-yard or rear-yard setback, which is why the zoning review happens before the location is fixed.
Standby generatorWhat size standby generator does a Manasquan home need?
The correct size is decided by the electrical loads the generator is expected to run, not by the square footage of the house. Central air, heat pumps, electric heat, well and sump pumps, refrigerators and freezers, electric ranges and dryers, pool equipment and EV chargers all count. Where a load is connected automatically, the generator either has the capacity for it or an approved load-management system controls it.
EV chargingCan a Tesla use a J1772 home charger?
Most Tesla vehicles can use J1772 Level 2 equipment with the appropriate adapter. Charging speed still depends on the vehicle and charger ratings.
EV chargingWhat is bidirectional charging?
Bidirectional charging allows energy to flow from the vehicle battery back to a home or grid when supported by the vehicle and equipment. It is more complex than ordinary charging and should be designed as a power system, not just an outlet.
