Bobster. Posted January 26, 2021 Share Posted January 26, 2021 (edited) Hi all, See my signature for my hardware. System is running in general mode. According to PV Master I have SOC Protect ON DOD on grid 60% Currently we have overcast weather. PV is low. Battery has been discharging. The system did start drawing from grid when SOC hit 39%. It held at 39% and drew from grid for about 15 minutes (according to portal) but then started drawing from battery again. Whilst I wasn't looking the battery got down to 26%. I have observed this behaviour before and reported it to the guys I bought the kit from. Does this happen EVERY time? I don't know. It doesn't get down to 40% very often. OK... any ideas about what I should do (that I can do, I'm not an electrician)? Edited January 26, 2021 by Bobster Quote Link to comment Share on other sites More sharing options...

Bobster. Posted January 26, 2021 Author Share Posted January 26, 2021 Well shoot! Now I go back into PV master and I see changes Charge Voltage has moved from 56.4 to 56.5 Charge Current has moved from 100A to 90.23A It wasn't me! I know that I don't know what those settings do or what they should be, so I leave them alone. Quote Link to comment Share on other sites More sharing options...
