I have 400 watts Renogy solar, the Renogy mppt controller and Victron BMV712 and Costco 6V Golf Cart batteries
1) My Victron BMV712 is not returning to 100% when not connected to shore power (shows changing output on the trends over past week)
2) When plugged into shore power it returns to 100%
I've attached a screen shot of the trends
So summary ...
when I'm on shore power everything works as it should (meaning if I disconnect shore power and run battery's down to say 65% then plug in to shore overnight then it resyncs every time). The problem I'm having is when I'm not hooked to shore power with nothing on its not resyncing even though the voltage is clearly meeting the set voltage criteria on victron and it is clearly receiving proper solar input (shows on victron "trends" graph).
