[RE-wrenches] Remote relay options

[Chris Mason]

Have you tried the generator with the inverter? I find some live together
just fine, and some trip out on over voltage. It all depends how the
voltage is regulated on the generator. Also, if there is constant load such
as air conditioning, you probably won't have an issue.
