Morning Guys, i am pretty new to the forum here and just installed my first solar system. My home. All has been going very well except for 2 batteries. My system consists of 4x pylontech US3000C Victron smartsolar 250/100 Victron quattro 48/5000 Victron cerbo GX to communicate between everything. When i first commissioned the system, i didn't check the DVCC option on the cerbo GX. I believe this let to a high voltage event on two batteries. I have since corrected the problem and the remaining two batteries are operating flawlessly, controlling the charge controller and quattro as expected. However, two batteries go straight into alarm mode as soon as i try and power them up. With the buzzer. I have tried them individually with no external connections still the same issue. I have ordered a cable from centurion solar that should be able to communicate between the pylontech's console port and my laptop. I will then attempt to find out what went wrong using batteryview. My question is, has anyone experienced this? Is there any chance of "resetting" the unit? Or is it likely going to need a replacement board of some sort? If so who can i send it to? Should i try and return the unit under warranty or is this not possible? I thought that the pylontech's had numerous protection systems in place to guard against this sort of fault? Thanks in advance for the help guys i really do appreciate it. Kind Regards James
