Multiplus with CCGX and BVM 700. Generator does not start when conditions for low SOC, set on CCGX, are correct. The BVM menu on the CCGX does not show a value for SOC, but the Multiplus menu on CCGX does show a SOC value. But the setting 'Synchronize VE.Bus SOC with battery' is unchecked. Should this be checked? Or is there another problem?
