My BMV 702 displayed voltage is 7V low.

My BMV 702 worked perfectly for about 3 years. Now it shows a voltage that is low by 7 volts. This measurement is verified by a multimeter, two solar charge controllers and the inverter. I've changed the inline fuse holders and inserted 1amp fuses. I've checked every connection for corrosion. I even recently replaced my entire battery bank with LifePo4. The BMV seems to accurately record amp hours in and out, but the voltage is just 7V low.

Here is a link to a power forum thread where I tried to get help with my problem: Power Forum

Please, I did check all of the suggested threads for answers. There is none.

Did you also checked the RJ12 data cable between the shunt and the monitor?

If nothing helps contact the Victron dealer from whom you bought it, you have 5 years warranty.
