try removing all power to the controller. Wait ten minutes. Then monetarily short out the inputs and outputs from the controller (no power on) to discharge any capacitors in the controller.
Now apply power from the battery bank, then add solar.
Attempt to set up the parameters you want.
I hope this helps.
