Commercial Rooftop Solar PV, Fleet EV Charging Stations & Mass Save / Municipal Utility Rebates
Electrical Dynamics helps Massachusetts and Southern New Hampshire facility owners slash operating kWh costs and meet corporate ESG mandates. Proven by our 139 kW commercial rooftop solar array for The MathWorks in Natick—generating 158,940 kWh annually and saving $22,252 per year—EDI engineers and installs commercial Solar PV interconnections, Level 2 / DC Fast Charger (DCFC) EV fleets, and high-bay LED retrofits.
Commercial Rooftop & Carport Solar PV Engineering (NEC Article 690 & 705)
Interconnecting a commercial 100 kW to 1 MW+ photovoltaic array to an existing 480Y/277V building distribution system requires rigorous busbar loading calculations under NEC 705.12, rapid-shutdown compliance under NEC 690.12, and utility interconnection protection.
- Ballasted commercial flat-roof racking, string/central three-phase inverters, AC combiner switchboards, and utility-accessible visible-break AC disconnect switches.
- Complete utility interconnection applications (Eversource / National Grid Distributed Generation & SMART Program metering coordination).
- Preventive maintenance, IV-curve tracing, inverter replacement, and thermal scanning for existing commercial solar arrays.
Commercial Level 2 & 480V DC Fast Charger (DCFC) EV Charging Infrastructure (NEC Article 625)
Corporate campuses, luxury multi-family communities (such as Broadstone at Bare Cove), and automotive dealerships (such as Herb Chambers Porsche/Audi) rely on EDI to engineer underground EV make-ready stub-outs, transformer upgrades, and automated load-management systems.
- Dual-port networked Level 2 commercial charging pedestals (ChargePoint, Blink, Autel, Eaton, Tesla Universal) and 480V 3-phase DC Fast Chargers (50 kW–350 kW).
- Dynamic Automated Load Management Systems (ALMS per NEC 625.42) allowing multiple EV chargers to share existing panelboard capacity without triggering a utility transformer upgrade.
- Full incentive capture across Investor-Owned Utilities (Eversource & National Grid Make-Ready + Mass Save) AND Municipal Light Plants (Reading Municipal Light Dept RMLD, Wakefield WMGLD, Peabody PMLP, Danvers, Wellesley WMLP).
