BYD internal error and low battery alarm.

Dears,


I installed a Multiplus-II 48/5000/70-50 with a unit of 4kW BYD battery. The system worked for 6 days without any issue. Then the system started triggering' Ground relay test failed ' . Then that error completely disappeared and the system started triggering internal error and low battery alarm. I have rechecked the wiring and the system several times, But I have not found any mistakes within my settings.

NOTE: I have installed several Victron and BYD systems, and this is the first time I am encountering such issue.


Thanks for helping.

The error is explained here.

The steps to check what is causing or correcting the error are here.

We once had a faulty pump control that caused this error, it had been wired in an interesting manner as well. ;)

If you have followed the procedure your next contact should be your dealership.
