Yes please thanks Mike, I'm certainly interested ... just as a spare backup inverter.
Very handy to know, thanks Mike. I probably tend to worry about the "what-if" and so change them all ... but it's nice to know it isn't always neccessary.
Regarding your way of determining the shorted mosfet, it won't really help too many others, but I have a Polar 850 benchtop tester that reads down to .1 milliohm and that is very helpful in determining where shorts are located.
Of course you need to regularly sharpen the probes and push hard to make it effective.
