Normally panel voltages are higher than the battery voltage. I look forward to a circuit diagram for this unit, maybe it will help explain the problem I have been having with a lower-power version using the same PCB.   Quote   Input reverse protection: YES I suspect that this is doing something strange at low supply voltage, ie below their rating of 10V.
