I've checked continuity and it seems the negative load output and the negative battery terminal are shorted or at least there is a switch. In this case it is an inverter that seems to have a too high power surge on turning on for the MPPT load to handle (it simply switches off).
It seems when I connect a load to (+) of the battery and (-) of the BlueSolar MPPT, the Victron app can track its consumption, which is great.
My questions are these:
1. Is this safe to do?
2. Will low voltage disconnect still work, i.e. will the BlueSolar MPPT switch off the negative load terminal? I'm using the BatteryLife algorithm, by the way.
