I have a Rich Solar 20a charge controller that I just added to my camper - paired with 2x100w panels.
After a long day of charging, the controller will still report ~40v at 5a even as the battery shows fully charged.
Does this mean the charge controller is still supplying the battery with that power, or simply how much power is available and could be delivered, if needed?
I feel the battery would have destroyed already if it was the former. Just trying to understand the display a bit more.
If the panels are supplying that, does the controller just deny the power? Or does it have to dissipate it as heat somehow?
Thanks,
Cameron
