The transfer switch is simple - I used a PowerMax PMTS-30 30 Amp Automatic Transfer Switch, $49 from Inverters R Us.

I took a used 30 A extension cord and cut it, I used the male end to hook to the generator, the female end to hook to shore power and used a section for the inverter input.
As for the converter - Actually, a easy solution for this is to install a simple 120v 18A relay from Amazon with "Normally Closed" contacts. Link to Amazon part is below. Costs less than $8. Got a pre-stripped lamp cord from Walmart for $3.50 and plugged it into the inverter and use it a to energize relay coil. and then switched the black wire on the converter outlet via the relay so that when the inverter is on, converter is off.
It sounds complicated, buts its really very easy and foolproof. You will never have both on at the same time and no manual switching necessary. Buy a cheap j-box and blank cover to protect it. Less than $15 for everything
