Transfering between the inverter and the generator

I figure it this way, if I have to do something ten times a day, then I think about maybe making it automated or remote. Otherwise a little exercise is excellent for me. DPDT relays are not expensive and 2 of them connected in parallel gives me sixty amperes switching on both L1 and neutral. If the inverter has a "seek" circuit, three different color LED's allow me the luxury of seeing what is happening in the power department.
