We engineers the electrical infrastructure for EV charging networks and battery energy storage systems — stamped single-lines, load studies, utility interconnection, and full permit packages for commercial and utility-scale projects.
SSE engineers the electrical infrastructure for EV charging networks and battery energy storage systems: Stamped single-lines, load studies, utility interconnection, and full permit packages for your needs.
Installing a charger is rarely as simple as mounting a box on the garage wall. We handle the load calculation, panel upgrade design, and permit paperwork so your charger goes in safely and passes inspection the first time.
Powers your home first, then tops off your battery and your car with sunlight instead of grid power
Banks your extra solar for the evening and keeps the lights on if the grid goes down
Charges your car overnight or straight off your battery. No surprise demand charges on your bill
We work all three systems (solar, storage, and EV) as a single integrated package, minimizing interconnection complexity and permit round-trips.
On-site generation offsets grid purchases and charges both batteries and vehicles at the lowest possible cost per kWh.
Capture excess solar, avoid demand charges, and hold capacity for peak dispatch or grid outages — from 50 kWh to hundreds of MWh.
Charge fleets or tenants from the storage buffer — avoiding utility demand spikes that make EV charging expensive without storage.
SSE engineers all three systems — solar, storage, and EVSE — as a single integrated package, minimizing interconnection complexity and permit round-trips.
