[RE-wrenches] AC combiners

[Dave Click]

Bill, typically inverters have a max OCPD that can be installed on their 
output, and these sizes are generally not large enough to accommodate 
two same-model inverters. And manuals often note that you need to have a 
dedicated OCPD anyway. At least if I were ever to double-up two 
inverters on a single breaker, I'd want to make sure I had clearance 
from the manufacturer to do so. Or... just buy the $75 box to combine 
the two.
