I’ve got 2 sites with Solis S6 Pro inverters and Powerline 5 batteries. Both sites are giving the same incorrect Voltage and SOC values causing the batteries to either die or the alarm to sound.
A firmware update of both the battery and inverter did not sort the issue out at all.
The voltages steadily decrease, then it rapidly drops from about 50.5v to 46v in a matter of minutes.
