Our inverter won’t turn on, we’ve been on the road for less than a week, it was working fine and then it suddenly died. We tested the connection to the DC, the fuse is good, it’s a 400amp fuse.
The data cables are connected, the light on the external BMS went from blue to red last night. We have 2 smart lithium batteries 200amp and a Victron VE bms and Oroin buckboost 100amp
PLEASE HELP. Is there any victron experts out there?
Hi there just to ask have you checked with a multimeter the voltages on the batteries altho not an ideal charge level way to check but just to ensure the inverter is getting a correct voltage, I would suspect if the bms has went to red maybe batteries are flat and inverter has shut down as the voltage has dropped below the set value, I would also check that the batteries are supplying power as seems the bms has cut the power and this would render the inverter off when that happened. I would give the batteries a good charge from a grid charger and read the manual on the batteries and bms to reset it properly. I would also disconnect the batteries from the system when charging and also charge them individually then assemble again.
I hope you get it sorted thanks david
Check the batteries with VictronConnect.
