[RE-wrenches] Generator automatic disconnect

[Larry Crutcher, Starlight Solar Power Systems]

If you mean automatic transfer, how would you trigger it since AC power will be present from both sources at the inverter output? Do you mean a N.C. contactor that would open on gen power, something like attached drawing?

What about running the genny through one inverter and putting a transfer switch on the AC out which opens the ac out. 
Meaning 100% charging but no loads.
