Outback Flexmax Charge Controller
Our sailboat came with an Outback Flexmax 80 Amp Charge Controller, and I would probably order the same thing if I had to get another one. We have it connected to 660 watt panels, and it’s not unusual for it to produce around 50 amps on a sunny day. I wish it had an iPhone app, but it’s really not necessary.
