I wouldnt do this but.....for theory it could be done and it would just average out voltage ,about 50 volts and amperage would add up with a certain loss..but it could be done yes??
I don't think it will work as a simple average. I presume you are using an MPPT controller which may get confused looking for the maximum power point. Also, I'm not sure how high a voltage (66 volts) you can backfeed a 33 volt panel with.
Apparently you have four 33 volt panels... why don't you just make two 66 volt strings?
