![]() But again in the wild I would be screwed since I wouldn't have shore power. Then I hooked up shore power to the Mutiplus and switched it to "Charge Only" then I turned the On/off switch ON and it did not trip. I turned the On/Off switch OFF again disconnecting the Multiplus from the battery. Would the preload resister still work in this scenario? The battery voltage with everything disconnected is 13.05 volts so it makes no sense to me why it would trip. So it seems to me the immediate demand for power from the inverter is tripping the BMS. I then turn the switch ON and it tripped yet again. I drained that off with a lightbulb power tester until there was no load at all. So with the switch OFF, I test the load and it was 2 volts. I keep running through all that has been written.īig Clue - So when I turn the On/Off switch to ON which connects the Multiplus directly the battery it trips. I guess I'll try the current surge limiter (CSL500) even though it's only recommended for a Multiplus twice my size.Īny other advice is greatly appreciated and thank you to all who have posted already. I'm going to try again in a few hours to see if the energy stored in the Multiplus caps will dissipate, but of course this is a terrible solution in the wild So right now I have no way to turn on my Multiplus without tripping the battery period. Also perplexed that I'm the only one seeming to have this issue, when so many use battle born with muliplus. I know Johnc that you said power can build in the caps and I get that, but according to all the documentation from Battle Born I shouldn't need any extra resisters for a 2000 watt inverter only when you start getting into the 4000 watt. ![]() I reset the BMS on the Battle Born and the DC power came back on, but as soon as I turn the Blue Sea On/Off switch to on it immediately trips the Battle born again. Once the battery tripped, I'm back in the same boat. ![]() Either way that should be able enough to run the appliance. Based on the voltage it had 40% battery, but it read 60%. Using my inverter at 1500watt usage and 60% left on Battle Born battery Voltage was 13.09 (both readings from Victron battery monitor) The appliance running at 1500 watts tripped the battery after 3 seconds of run time. So I thought I had this sorted out and was just not going to use the on/off switch, but that didn't pan out. Also, I have had Victron pros in this community validate my schematics, but happy to post again. It seems even the distributors of Victron don't know how to service them. ![]() I live in Colorado and I can't find anyone I can pay to come and help figure it out. 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. I haven't even started using the Inverter yet just the charging. Both the Multiplus and Battle born are brand new. It almost seems like something is bad with the Multiplus or Battle Born. I have checked all the wires and everything is tight and isolated. Then it starts this vicious cycle of tripping the battery every time I send power to the Multiplus. This usually starts happening when I turn off the power to the Multiplus without turning off the Multiplus first. Then I have to disconnect the battery and reconnect to reset the BMS. ![]() 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. Hello, I have a Multiplus 2000/12 connected to a single Battle Born Lithium battery. ![]()
