I have a small travel trailer with two 90W 12V panels wired in series.I have a Victron 100/30 MPPT controller.

I want to add more panels.  I can fit 3 50W 12V panels.

All the panels have a Voc of 22 volts, so I'm thinking I can parallel two of the 50W panels, and then run the two 90W in series, one 50W in series, and the two paralleled 50W in series as well.  Total Voc is 88V.

Would that work?

    Don't combine different panels on the same controller.
