boondocking, need help asap....
Just put a new controller in for my 55w solar panel. It charges batts (2 12v) to full charge, but once the sun starts to go down the batts start to discharge and the controller shows red by morning. W...

In order to get anywhere near the correct SOC using voltage, you have to disconnect all charging sources and loads, wait 24 hrs, then take a reading. When I come home from a trip, hook up the charger, the batteries voltages eventually comes up to 14.8V. Guess what? They're not fully charged. Eventually the charger goes into float as 13.65V. Guess what? They're STILL not fully charged. Eventually 50W will get your batteries in the high 90% range but it will not be in a day.
the new morningstar is working, solar is charging batts to full every day I have sun! I checked with a volt meter.
End of story!
