Hi,
I have got my hands on a Tesla Mod 3 Performance 75kWh battery. I disassembled the battery and have now the battery strings (96S) 400VDC available. The charging will not be the problem, as I designed the PV to deliver me the voltage range of 379-418VDC, but the reuse into the inverter will be an issue as long as I can not control the discharging current. Does anyone have experience with DIY DC-coupled HV Batterie storage?
