Hi,
after running several months with no issue at all, the MP II swicthed off and no message appeared on the GX not the VRM alarm log. Later i discovered irregular behaiviour of the SOC coming from the BYD BMS (a call to EFT is already opened) - nevertheless, i would expect some sort of logging from the MultiPlus II about that - any other location/source i could look at ? The only change within the last 2 weeks was updating the GX to 2.60.
best regards,
Martin
Is this still an issue?
The BYD may not have reported an issue to the gx at all. Is there a way to interface with the BYD at all maybe find out if there was a weak cell and the battery shut down?
The other thing to check is if the multi's own battery monitor is checked and configured. I have had systems when the multi has noticed an issue on ve bus voltage but the batteries say nothing yet have a weak cell and shut it off obviously dropping the voltage of the system and causing a shutdown.
