My AC200P is not charging properly from PV. When I plug in the cable it starts working as expected. I am actually using a 72v battery as the source so I know it is getting plenty of power but the amperage starts dropping almost immediately and after 30 minutes or so will drop to 0 Amps even though it is still at about 80 volts
It is set to PV and the temperature is at 29C. I just ordered the DC7909(F) To XT90(M) Cable so I can see if the power supply will work properly on the PV side. Does anyone have any ideas?
