Portable panel
The Renogy 100W is what we use. It's Voc is 21 some volts, but the reality is it produced more power than the rooftop 190W panel. We have a Victron 100/20 MPPT controller for both.
Have considered separate controllers which makes the voltage mismatch irrelevant.
Has anyone considered rewiring so the external solar port is in series with the rooftop panel? Need a switch to bridge the external port when it's not in use. That would bump the charging voltage up to 46 or so.
