Hi Warren and all
In attachment is the circuit Tom McKay used with his dual-RV system in  pdf format...
There is lots and lots of circuits and very great  photos and info in FILES section here on EVGRAY if you can get into it all about this- look for the folder that is titled "SPI high power invertor" (which is the "pig screamer")
and look for the author being "Ve3ttt" (who is Tom McKay)
you have to scroll down about halfway through all the folders in FILES section to find this folder and when you find it you will see everything you want to know .... I remember his invertors ran on 24VDC, he used series transformer from run cap phase technique to get OU in each of the two motors and used audio torroid power transformers two of them in series from what I remember...its all there to see and study...It is Hectors looping circuit basically - Tom said it took up the entire floor in room at his house...
