[RE-wrenches] Small Cabin inverter

[Chad Waits]

Thanks gentlemen. I had heard rumblings on the list of the downturn at
Magnum. Shame...

I was able to talk them into reconfiguring the bank to 24V. I will take a
look at Victron, but I would really like to offer them the simplest
solution. The Internet is nil there and the fella that lives there most of
the time doesn't even know what a smartphone is.. Country boy you could say.

Appreciate the insight.
