I have had a successful small solar setup with the Victron 100/20 Bluetooth enabled controller and three 100w panels in series to make 60v PV input and 80AH worth of lithium-ion batteries and so the highest voltage charging was set to 12.5v, this setup lasted about half a month with no problems. I come home today to a blown fuse and the battery terminals shorted to almost 0ohms. I can still access the controller from Bluetooth and resetting to factory default changes nothing. when i checked the history tab on the controller the highest PV voltage was 126v and considering three 20v panels in series can not possibly create that much i feel inclined to believe it may be defective - although checking the current voltage still says 59v... any help would be appreciated
