The GX device is supposed to get its power from the VE.Bus BMS' load disconnect pin per the manual.
The GX device controls the BlueSolar MPPT through VE.Direct.
In case of depleted batteries, will the GX off state default to letting the MPPT charge or not?
If communication to the GX device fails then the the MPPT will fall back to its internal charge settings. Make sure that the MPPT is set up for your batteries so that they continue to be charged correctly in the event of a communications failure.
