Greg,
Might not be the answer your looking for, but I understand you're much
better off to mount the inverter near the batteries and use short DC
cable runs. This might make your AC wiring more complicated, but it's
the best way to go. That's why most people put golf cart batteries in
the generator compartment and the inverter next to the AC breaker
panel.
As far as your electronics expert, keep in mind that handling large
amounts of DC current is a different animal. Go with the manufacturer's
rec's.
