I have 754 amps at C20 of tubular 2v deep cycle batteries, to charge these I have 530w of solar and a 5kw diesel generator. I have a 12/3000/120 inverter charger from victron and a bmv 712 both only a couple of months old.
I can adjust most things with victron connect either with bluetooth or with a mk3 usb. The multiplus is wired correctly with the correct victron spec wiring as is the bmv all negs go to the correct side of the shunt etc.
