Ah, now I understand. No, it wasn't cold when I was fighting with it, about 100 degrees.No offense taken - I was just wondering if you kept with the PWM controller or Redarc found a solution.
I put together a battery box for my refrigerator, I have a cross country road trip planned, didn't like running it off the inverter/plug in the back of my tacoma, kept forgetting to switch it back on after stopping to eat or gas up.
The next item will be connecting it with the SCC, right now the plan is charge it up at a site that has electric overnight.
edit: perhaps you were talking about the cold panel - in grubworm's post above it was mentioned the series voltage, solar panels put out higher voltage when they are cold, I saw Idaho in your signature, so assumed a low temperature.
Since the PWM box works, I hard wired it in and that's my solution to the solar issue.
