Instead of continuing to fiddle around with two sort-of partial 
solutions that do not actually solve the problems, why not just buy one 
or more proper online UPS boxes?  Several of us have mentioned specific 
part numbers, where you can look for them at decent prices, and how to 
maintain and care for them.

This alternative would solve decisively the problems you (and Bob) are 
seeking to solve, and the cost is not extravagant (it would be even more 
economical if you hadn't already bought the offline UPS and the CVT -- 
perhaps you can sell them to recover some of the cost).

It is details like these that distinguish a "home time lab" from "a 
bunch of test equipment in the basement."

Best regards,
