Every day at least once the battery gives an overcharge warning, at this point it will not charge or discharge.
Meaning I have to inport from grid whan my batte,ry is almost full.
Also, I cannot charge the battery from solar it exports to grid.
This ia a major issue, I have had the Battery system for a couple of weeks and so far it has performed badly.
If you’re having these problems, first port of call is your installer.
Battery Management System 3015 can result in overcharge warnings but these are usually transient. Might be worth you upgrading to BMS 3017 if you’re not on that version.
But get your installer involved, they are your first port of call for any such issues, and if there is something wrong with the kit they would be the ones to resolve/replace it
