I have installed on my van a smartsolar mppt from 2 years ago, it was allways working fine, but a few days ago it stoped the charge. The blue led is blinking (bulk) and in the app it says the smartsolar it’s stoped. The only way it starts charging again, was disconecting the batery and the solar panles, wait for a few seconds and conect it again. It hapened 2 times in 3 weeks. Few months ago I changed the battery from Gel to a liFePo. My solar panel it’s a 200w panel, and normaly works at 15/20v. It could be a problem? Any clue?
I’d start with the troubleshooting steps in the user and installation manual, and work from there: 8. Troubleshooting
Thanks, but the point in my failure is that if i disconect, and conect again it works fine for some days… The battery it’s almost new, and the loads are minimal… it’s not conected to any bms only to a SmartShunt…
