I need some advice here. We have had 6 of these Vatrer batteries on our cabin for about 7 months ( my dad lives off-grid in the mountains in Colorado) All summer they stayed at 100%, and maybe in the morning before the sun came up 65 to 75 % then right back up to 100 % by 2 pm ( or sooner ) Now that's its winter and we have one of our larger solar arrays seeing a lot less sun, plus the furnace fan all night. We are not over-paneled for winter. Long story short, I'm not always here and did not want my dad running them to zero % , which has now happened twice. So I came back up and used the Overkill solar app to change two of the settings. One I saw that the battery pack under voltage is set to 35.2 volts ( 35200 MV ) , wow on a 48-volt battery ( that is really 51 volts ) 35 seemed too low. I changed it to a 38-volt package voltage cut-off ( 38000 mv ) . I also changed the cell under voltage from 2200 MV to 2250 . The hope is that when we run the battery to zero % the cells are really higher ( maybe 10 -15 % ) . Im not an expert on the BMS setting could someone tell me if I did right? Should I change them back? Is there any other setting I should change ? Oh I also changed the high voltage cut-off from 60000 MV volts to 59950 ( MV )
thanks
