Hi Mark This was a big advantage of the older FX inverters was the use of the balancing transformer. The new FXR can’t use it.
I can’t find but I had to call OB to get some info on how much you could out of balance a Radian inverter. It was like 60% ,could have been a bit higher but wasn’t 90-100% for sure. Schneider xw is 75% I don’t know about magnum. And yea gotta try and figure out the load balance.
