Thanks, Tecnodave! I am glad to hear that it is possible to connect the load output of the inverter to BOTH L1 and L2 inputs on the transfer switch. The only 240v appliance we have is a dryer which we obviously wouldn't use during a power outage. Are you familiar with this Cummins 100A transfer switch? I assume it would work for me:
Not familiar with that particular product, but am very familiar with Cummins/Onan , very good equipment. They are the leader in 24/7/365 no fault no fail service for hospitals, etc where electricity must not fail under any circumstance.

I do not hesitate to recommend Onan/Cummins equipment, They are built to last..
