Existing grid connect system based on Victron Easy Solar 48-3000-LG REsu10 system was modified to Multiplus II 48-3000. After the recent Firmware upgrade to have more information for Error 11 message (as recommended for sysems displaying error 11), the system started to provide low voltage alarm L1 messages. On VRM it appears that battery voltage oscillates between 48V and 60V (in very short intervalls) even so the actual voltage on terminal is stable at approx. 55V. System is not charging or discharging anymore and switches off. We understand now that Multiplus II appears now to be not approved with LG RESU 10. Does anyone have a suggestions without switching back to the standard Multiplus or changing the LG batteries to e.g. BYD or other non managed high cycling battery like Shoto LLC Any suggestion is welcome
