Thanks Buck and sorry for the slow response, the Mastervolt shows either positive or negative amps which I take to mean charge or discharge. We had another night with shorepower recently and since then the batteries have remained at 90%+ with the solar charging alone so I’m thinking that maybe it is just the new setup settling down and tweaking the settings has helped.your master volt is probably confused by the float voltage 13.8. I'll bet the 10A you see as charge is actually 10A being used by your boat. Switch everything off and look at the "charge" current. Ill be it's milliamps.
