I saw a similar question asked but from another angle so I thought I would try and ask it from my perspective.
I am going to be buying the Victron Multiplus 3000VA inverter, and for now, it looks like I will be pairing it with a 250A Daly Smart BMS. The BMS will be connected to 8S Lishen 280A cells. Obviously, I want to insure the BMS cables can handle the full draw from the inverter.
The 250A model is rated for 250A continuous power. I just asked the rep what the battery lead cable sizes for it were, she said 2AWG. 2 gauge is rated for 181A on the charts I have seen. The cable charts show a single 1/0 or dual 2's. Since I am looking at "generic" cable specifications, maybe they don't apply to this situation.
The Daly rep indicated they tested the cabling, and I am sure they did, but could she be correct that 2 gauge is adequate, or even more than adequate?
I noticed the drawing for the BMS logic board has two connectors, so it could support dual wires, but it doesn't seem to be how they are wiring the 250A model for sale.
I bet someone else has had the same question and knows what to use. Thanks!
