question

Have you checked the wiring of the meter for loose/corroded connections? What is the meter connected to? Any fuses/switches in between that could cause resistance?

Thanks here’s an update. I traced the wiring from the house back to the monitor. Then I cleaned all the connections at the main wiring harness at the house bank. The voltage went up from 11 to 13v after that. So apparently it was resistance at one of the connections from the corrosion Thankfully a faulty simple fix, just took a bunch of sanding/ brushing

I am having a similar problem. Cleaning all the contacts did not solve the problem. The unit is showing 11.5 volts on a 24v system (so designated in the setup). On the backside of the unit the voltage shows as 26.4, The display is constantly blinking. It says 'charge battery full' on the display. The unit was installed in 2004 so I am suspicious of it, as it is quite old. Before I install a new one I am wondering if there might be something else going on.

If you're measuring the full voltage at the 702, but it shows low, even after cleaning all contacts at the 702 end, the fault must be in the unit.

thanks for the reply. After so many years it is not surprising. What is confusing is that the Victron solar regulator is also blinking, same cadence, as is the Multiplus. If I turn off the Multiplus and disconnect the solar, the BMV still flashes. I have checked/cleaned all connections. Any thoughts?

Charge Battery Full signifies that the unit needs to be synchronized. I had synchronized previously. I did so again and the Charge Battery Full message disappeared, now just Battery full. I checked several functions and the connections to both + and -, all clean.
