Samlex manual says surge rated to 466 amps, so I guess I’d better go with 500a on the fuse. I don’t see much in the way of Class T fuses at 500 on Amazon or am I missing something? See plenty of ANL.
The wiring is fine, I have a run of maybe 1.5 feet of 4/0 from batteries to inverter. I assume i’m Ok with 2/0 between the batteries, would really rather not have to redo all the 2/0 I already made.
Itinerant1, it’s hard to tell from your photo since your cables are all so well managed along the batteries, you’re running 3/0 everywhere?
ANL is much faster so maybe 350 to 400.
