ChargePoint EV charger in Lawrence Township, NJ by Green Sun Energy Services.
Deborah from Lawrence Township, NJ has been a Green Sun Energy Services client since October of 2024. She and Charles bought all three trades on the same day, and all three were in by early January – the generator, then the charger the following morning, then the array.
A 22 kW Generac on a managed whole-house switch
Commissioned on 18 December 2024. The calculation asked for a minimum of 17 kW under NEC Article 220 Part IV and a Generac rated 19.5 kW on natural gas went in – 22 kW on propane – behind a 200-amp managed whole-house transfer switch with two smart management modules and whole-house surge protection. The house is 3,200 square feet with a refrigerator, a dishwasher, a washer and a gas dryer. The management modules were specified knowing a car charger was going in the next day, which is the sort of thing that only happens when the two jobs are bought from the same people on the same afternoon. It sits on our Diamond plan: annual maintenance, extended parts-and-labor cover and remote monitoring that Green Sun runs directly.
A ChargePoint on a 60-amp circuit, the next morning
19 December. Hardwired, J1772, on a dedicated 60-amp breaker at 11.5 kW – roughly 36 miles of range an hour – with a 100-amp management module. The charger draws 47 amps continuously, which is a large addition to any panel and a very large one to ask a generator to carry. Installing it the day after the machine went in meant the two were never designed in ignorance of each other.
23 panels and 10.58 kW
Live on 3 January 2025: 23 REC 460-watt modules on a SolarEdge HD Wave inverter, estimated at 12,636 kilowatt hours in the first year, with 236 feet of critter guard closing the sheltered gap beneath the array. The roof needed nothing, so the panels went straight on with no tear-off to schedule around.
Three trades, eleven weeks, one panel
An array, a standby generator and a fast car charger all hang off the same 200-amp service here, and they were specified as one problem rather than three. The generator got its management modules before there was a charger to manage. The charger went on a circuit sized in the knowledge that a generator would sometimes be carrying it. The array went up last, onto a roof that needed nothing, reducing what the house draws from the service on every ordinary day – and contributing nothing at all on the days the grid is down, which is precisely why the generator is there. Bought separately across three years, each of those decisions would have been made by somebody who could only see a third of the house.
Mike was on time, friendly and efficient. We have had very positive experiences with GreenSun.
Green Sun Energy Services replied
Thank you, Deborah, and Mike will be glad to hear it. Yours is a three-part house in Lawrence Township: a solar array, a standby generator and an EV charger, each doing something the others cannot. Keeping all three on one service relationship is what makes a visit straightforward rather than three separate conversations.
Why Deborah chose Green Sun Energy Services
Professional home EV charging made simple, from electrical design through final inspection.
More than solar panels: a professionally managed energy system, from design and permitting through installation, inspection, activation and ongoing support.
Complete backup power, from sizing and installation to the service that keeps it ready.
What makes Green Sun Energy Services different
- EV charging: installed with certifications from Qmerit, ChargePoint, Enphase, SolarEdge and Tesla, by a licensed electrician and fully managed by our team. On this home: a ChargePoint CPH50-HARDWIRE-L23 EV charger on a 60-amp circuit.
- Solar: design and installation supervised by a NABCEP-certified professional (#PVA-111016-016148), with SolarEdge optimizers on every panel so each one reports its own output. On this home: a 10.58 kW solar array of 23 REC 460AA-PURE-RX-DC panels, a SolarEdge SE10000H-US000NNC2 HD Wave inverter, the Snap-N-Rack mounting system and 236 ft of critter guard.
- Standby generators: installed and serviced as a Generac Authorized Sales and Service Dealer, by factory-authorized Generac technicians. On this home: a Generac 7042-2 standby generator (22 kW LP / 19.5 kW NG) running on natural gas, on a 200-amp transfer switch (managed whole house) and serviced by Green Sun Energy Services.
- Warranty: backed by a 15-year solar workmanship warranty and a 5-year generator workmanship warranty.
- Local: locally owned and operated in New Jersey since 2010, NJHIC licensed (#13VH06229000), with completed EV charger projects, 25 completed solar projects and 13 completed standby generator projects across Mercer County and 91 EV charger projects, 361 solar projects and 621 standby generator projects throughout New Jersey.

Questions from Lawrence Township homeowners
Standby generatorWhat gas pressure does a generator need?
It is model-specific and has to be read off the specification sheet rather than assumed. A current 22 kW model, for instance, specifies a minimum natural-gas pressure of 3.5 inches water column. Different models carry different requirements.
Standby generatorIs an emergency shutdown required?
The 2023 National Electrical Code contains requirements addressing emergency shutdown of generator prime movers. Whether and how they apply is determined from the generator's rating, its location, the model and the installation, and the factory equipment is evaluated against them rather than presumed to comply.
Standby generatorDoes a generator in Lawrence Township have to sit twelve inches above the flood elevation?
That figure should not be treated as a universal rule without looking at the actual property. The required elevation can depend on the flood-zone designation, the municipal freeboard, the Design Flood Elevation, Coastal A or V Zone conditions, NJDEP requirements and the applicable building-code provisions. Each flood-zone installation is worked out individually.
SolarWhat does the inverter do?
It converts the direct current the panels produce into alternating current the house and the grid can use. Residential systems generally use either a central inverter, with optimizers at the modules where applicable, or a microinverter at each module.
SolarAre certificate payments guaranteed regardless of production?
No. Certificates depend on eligible measured or programme-recognized production, so a system that produces less creates fewer of them. The value attached to each one may be fixed; the number of them is not.
EV chargingCan lightning damage an EV charger?
Yes. Chargers contain power electronics and communication components that can be damaged by surges. Proper grounding, bonding, and surge protection reduce risk but cannot eliminate all lightning damage.
EV chargingDoes installing an EV charger mean upgrading the electrical service?
Not necessarily. Adjustable charging equipment and listed energy-management systems can reduce the charging load when the rest of the house is drawing heavily, and the code specifically recognizes energy-management approaches for EV charging. An upgrade is one answer, not the only one.
