Yes I have a fuse on the output of the solar between the shunt and the DSSR20s!
So just to confirm, the negative battery bus bar will have the four 10 gauge wires from the panels (in my case from the DC Circuit Breakers) and four more 10 gauge wires from the negative side of the DSSR20s?
EXT4- is a single wire from the SBMS0 to the small grey "Batt" on the first DSSR20 then daisy chained to the rest of the DSSR20s
EXT4+ is a single wire to the positive bus bar with a resistor (should this be to the most positive bus bar of the battery pack or is the positive bus bar OK?)...not a twisted pair with the EXT4-
PVn and PVp are a twisted pair to the PV Shunt
ADC1n and ADCp are a twisted pair to the Primary Shunt
I will have a Victron 24v 3000w Multiplus and a Victron 24 v to 12v DC to DC 70a Buck Converter. Do these get connected to the EXTIO3 or EXTIO4 for controlling charge and loads? Can they be connected directly or do I need a Victron Battery Protect too?
