I'd really appreciate some advice - completely new to this so apologies if silly question.
I see Victron recommend 70 mm2 cable and a 300amp meg fuse to the Multiplus 12|2000.
I have a 230amp lithium battery (obviously less than 300...)
should I go for a smaller fuse in this case? and what wire size? if length of cable relevant, definitely <5m, probable around 1m
Keep the wiring size large. 12v systems are notorious for volt drop under load causing other issues. I would get even bigger of it fits.
2000 ÷ 12 is 166A. So your fusing needs to be larger than that or you will have to be carrying spares all the time because of seemingly random blowing.
What nominal discharge amps does the battery bms allow? AH is not the way to look at lithium suitableness for an inverter.
thanks for getting back to me so quickly
max continuous discharge is 200a
