Yep.... I've been seeing issues for weeks now....almost since first install of SA. I thought the Dashboard values seemed to add up properly for the first week or so I had it running but went to hell after I added additional batteries to my setup (far from certain that was the reason cause I even disconnected them and went back to previous battery configuration and still had the discrepancy in dashboard values).
For now I'm living with it and hoping that once I get a few full cycles on that batteries it will correct itself or if there is a bug in SA it will be corrected in a future update.
