Excellent - thanks for the details, Eric! I'll probably go with
something like that when it comes to powering the engine bank (the setup
I'm going with now is just for the house side.)
Incidentally, does anyone have a good recommendation for a panel-mounted
voltmeter/ammeter pair? Ideally, I'd like a backlit (blue) LCD display
with large digits (~1" high) where I could see both the volts and the
amps at the same time. An ammeter that goes to 300A or more would be
perfect.
