Victron Color Control Keepsn Throwing Low Voltage Alarm!

[Bravo30]

Victron multiplus 2k, BMV 712, color control and 2x125ah stark power lifepo4 batteries.


Ok, everytime I turn on the inverter I get a Low voltage alarm from the color control and at the same time it reads a 100% SOC. The BMV and BMS both say 13.6v @100% SOC but the color control is saying low voltage @ 9.34v while the alarm is set at 11.5v

I set the low voltage alarm to 7v just to see what happened and when I turned the inverter on the alarm tripped again so no matter what the alarm is set at it will will always trip.

-I tested the cables going into the inverter at the posts after the fuse and they read 13.6v

-I tested the batteries directly and they read 13.6v

Why is everything reading 13.6v except for the color control? I should also add that there was a glitch on the screen yesterday. The pages overlapped. It only happened once.

I called victron an they didn’t have an answer but think the batteries are causing the issue.


(The picture below is when I had the alarm set at 12.9v sonit tripped at 11.26v)

I should also add that everything has worked perfectly for the past 2 weeks on the road.

Now it’s reading 9.49v

Ok, I figured it out. It was the main Class T fuse on the 2/0 cable going to the inverter. I had to test it a number of times to get a low voltage reading. 15 times it would say 13.6 then on he 16th it would read Low 9 volts. When I initially tested it I only tested it a few times so I was getting 13.6 by luck of the draw I guess an figured It was good. I replaced it with a spare and everything works fine now.
