Envision’s Off Grid Electric Vehicle Charging Stations In a recent discussion about the extent to which Demand Charges are an impediment to development of DC fast chargers EV Fast Charging Disincentives , the solutions explored included primarily a) regulatory reform of the rate design & b) technology solutions involving battery based peak shaving. A 3rd solution could be added, for strategies involving charging with behind-the-meter renewable generation. Solar carports can offer such a solution, with various configurations involving batteries sized to support L2 chargers. Most of the PV carports are grid-connected but can be islanded. I recently discovered a system that is completely off-grid. So far most of the carports I had seen were intended to provide power to buildings, with EVSE’s an incidental feature, and few if any carports PV systems were sized with sufficient battery capacity to support DC chargers at or above 50kW.
