Review on OutBack Power FLEXmax Charge Controller by Jason Sisawang

Revainrating 4 out of 5

Beware! Programming requires Mate3 for $425.

Great charge regulator but this is the only one I've seen that doesn't have a simple menu or regulator like every other charge regulator on the market. Not compatible with MATE or MATE2. REQUIRES $425 MATE3 and is not intuitive. Definitely needs programming to charge LiFePO4 batteries. I assumed there would be a small screen and control buttons behind the gray plastic cover like other devices. Nothing.

Pros
  • Energy Regulator
Cons
  • Slightly dented
