What is “#3 Expected Devices Error”

On a split-phase multiple 12/3000/120 I get an “#3 Expected Devices Error” followed by a “low battery error on the Color GX panel when removing from the 50amp RV park service and the slave goes off-line. Batteries SoC shows 99%. All works well when plugged in. No errors or notifications.

so what happens when you turn both off and back on via there rocker switchs does all then work fine, ?????


also if they do work fine then with the CCGX what happens if you go to the list select multiplus and turn them off, wait 3 min does a error occur, then if you turn it back on they all work fine. I only ask this question out of interest. (a error should not show)

I solved the same issue last month:
The negative battery connector of one of the inverters was very hot because the bolt was not tight.
My solution: Tightened bolt.
