Charge controller recommendations
I have a small solar charging system consisting of two 12v 75w panels wired in series and a failing cheap MPPT charge controller. I may be acquiring another identical panel too. I'm currently leanin...

Those are very nice panels! Being able to configure them to 6V makes them very versatile.
Your options are:
1. Go with a low cost pwm controller. Wire 12V panels in parallel. It's easy to add third panel.
2. Go with medium cost mppt controller (<40V Voc). Wire 6V panels in series. You can add a third 6V panel.
3. Go with medium cost mppt controller (<30V Voc). Wire 12V panels in parallel. You can add a third 12V panel.
4. Go with higher cost mppt controller (greater than 70V Voc). Wire 12V panels in series. You can add a third 12V panel.
