On my boat I have a MultiPlus 120/3000 which I use when connected to shore power, or with a diesel generator. I also have a propulsion engine with a large frame alternator and a Balmar voltage regulator.
I understand that I can wire the relay from the BMV-700 to the Balmar voltage regulator, and using a Victron SolidSwitch 104, I can program the BLM-7xx relay to enable/disable the Balmar based on SOC%.
I also understand that I can wire the relay from the BMV-7xx to the MultiPlus - via the AUX1 or AUX2 inputs - I can similarly get the BMV-700 relay to enable/disable the charger/inverter based on SOC%.
Is there any reason I can't wire the BMV-7xx relay to both? As in wire the BMV-7xx relay to a terminal block and then from there run a wire each to the SolidSwitch104 to control the Balmar, and another wire from the terminal block to the MultiPlus.
As far as I understand how electricity works, this should not be a problem. I was also thinking I could run a 3rd wire to a latching relay connected to the solar panel charge controller (a MPPT 75/15).
Will this work? Thanks!
