Re: [RE-wrenches] Discharging a high voltage battery

The idea is to use an inverter manually as a current dump to the grid from the EV battery as opposed to just driving around to discharge the battery. No automation or communication required. This is not for a permanent connection. So they will connect, discharge, then disconnect when done. If t

Hi Larry, I have no idea what would happen if you connected a DC high voltage (340 v) battery source to a PV inverter. I guess my point is that it isn’t designed for it and likely wouldn’t work. Maybe it would? I have to think that both the inverter and the EV would have some sort of logic or ci

Hi Larry, I doubt the MPPT algorithm would be able to actually vary the voltage of the battery bank like it can the PV string. Also, I think that the actual MPP of a battery bank would be much higher amperage than the inverter could export. It would be an interesting to see if it would just max

Hello August, Help me understand your point. If the MPPT circuit is sweeping, it will see the same voltage everywhere. Would it not just continue sweeping because it can’t lock on? Or perhaps it times out? As long as it is producing power during that process, won’t it be fine? Thanks to all f
