This is true. I just don’t know what actually happens to a unit when you flood the capacitors and don’t use a pre charge resistor. Other then just a spark if it isn’t done right. I know it’s something bad though. ? anyway that’s the only thing he mentioned that sounded like it could cause a problem. Otherwise I’m not sure.If thats the case it's still a defect that you get a PV error when the issue is the batteries.
