Hello, I have a Multiplus 2000/12 connected to a single Battle Born Lithium battery. Every now and then when I turn the Multiplus on (using on/off switch, not the hard switch on the Multiplus) it trips the BMS on the Battle born. Then I have to disconnect the battery and reconnect to reset the BMS. I have no idea what is causing this. This usually starts happening when I turn off the power to the Multiplus without turning off the Multiplus first. Then it starts this vicious cycle of tripping the battery every time I send power to the Multiplus. I have checked all the wires and everything is tight and isolated. It almost seems like something is bad with the Multiplus or Battle Born. Both the Multiplus and Battle born are brand new. I haven't even started using the Inverter yet just the charging.
I did fire up the inverter on a test run and the buzzing was really loud (normal?) and then it too tripped the BMS after 2-3 seconds.
Thanks for any help. I live in Colorado and I can't find anyone I can pay to come and help figure it out. It seems even the distributors of Victron don't know how to service them. Also, I have had Victron pros in this community validate my schematics, but happy to post again.
