Need help picking a charge controller

[m0rtyseinfeld]

I'm putting together a small solar setup for our family cabin. We have a 12V 200Ah LiFePO4 battery and about 600 watts of solar panels. It's just for backup in case the power goes out. Just enough to run lights, fans, and a little fridge.

I'm not sure what kind of charge controller to get. Is it MPPT or PWM? What size do you think would work best? Hoping you can help me out here. Thanks!

you know, for your setup, you need an MPPT charge controller. While PWM controllers are cheaper, they are much less efficient, especially with a system of your size.
An MPPT controller is better at converting all of the power from your panels and will be much more efficient, giving you a faster charge time and more energy throughout the day, especially in cloudy conditions.

For reliability, I'd go with Victron or Renogy controllers. How are your panels wired, series or parallel?
