Provide sufficient energy to replenish the 405 EV daily consumption. Together with surplus energy during the day, it is more than enough for rolling out EV charging points to all the flats. Beside the wee hours, Shadow Power is also available throughout other time sections.
High utilization rate of charging power PLUS No overloading guaranteed. The PSN-EVC System by DL TECH is among the first which can harness Shadow Power for EV charging purpose.
