[QUOTE="David_1224, post: 554547, member: 37856"] That's interesting and maybe worrying. [ATTACH type="full" width="354px"]16667[/ATTACH] This is a typical SOC plot for my system. The first overnight charge started at 00:20 and stopped 01:20. It then discharges back to the 12% level and then you can see it slowly looses charge until 05:55 when the cycle is triggered all over again. Following this second event the SOC is still at 12% when at 09:10 there is some excess from the PV and solar charging has kicked in. Does this suggest there's an issue with the battery?? I have to note however that on your plot there appears to be structure in the minimum SOC section of your plot which looks like the charge IS being adjusted. Can't really tell due to the scale being dominated by the 100% charge. Might be interesting to look at the raw data between 12:30 and 23:30 to see what that activity really is. Shame that it's not possible to pick scales and time periods for the plots so detail like that can be blown up. Would be Soooo much easier. [/QUOTE]
