Thanks for the reply. I have to correct myself. This is the output from the solar panels. I don’t imagine this is going straight into the batteries.

Ah, I think I assumed that the amperage was going to be twice as low because the panels were described as 24v. Is this a mistake I made?

I think you’re correct. It’s 520W. The Renogy Rover 40A. That means i’ve got too much solar power for the SCC. I wonder why this only happens with the second battery connected. Maybe it limits the amount of amps going into the battery? Best plan of action, i assume, is buying a heavier SCC &...
