FLM03E shows negative voltage?
by
onHi,
My Flukso FLM03E shows a fair amount of negative voltage. I have 2 small solar panels. But even during night time when the panels can't generate I see negative voltage being reported?
I have a 3 phase + N installation and reporting via math 1 + 2 + 3.
Is there any way to check or troubleshoot this?
Andy.
