I have a couple of panels in series that produce 70V into a charge controller dropping to charge 12V batteries.
Every few hours the voltage drops to 14V on the panels before climbing again slowly over a period of time (no shading). I have two identical arrays, and they both do exactly the same thing.
If i turn the isolation switches off and then back on, they will show 70V again.
Any ideas please?
