I've known for some time I was under what I should have for wire feed from the battery banks. only 2 2-gauge per pole.
But I fused it accordingly and rarely ever stress the limits,
Mostly just don't have the battery capacity to do such for any length of time, and really the decided on normal loads are way under the current capacity.
This is WAY bigger than I need ( just how I like it)
Troubles I see coming though is that the lugs I will need are probably going to be way to big for the panel.
