The issue presented in post #28 was already addressed by Casey, correctly:

The PD Converter output goes through the "el cheapo" 80A circuit breaker and into the "positive" distribution block, he does not have the PD converter going through the fuse board from a "Converter" terminal WFCO fuse board terminal to reach a "battery" terminal on the same board.

One of the two other leads leads from reaches the battery pack (somehow, not visible) and the other feeds the fuse board. I personally have dual 8-AWG stranded copper reaching into both of the larger ports on the WFCO fuse board, each fused at 40A, but that is not completely optimal. It is a compromise based on the expectation that fuse board might have trouble distributing a lot of power from a single port. An adequate single wire, perhaps AWG-6, would probably not fit into either of the terminals, and a nonstandard oversized ATC fuse would be needed on that port.
