For the limited sized systems the OP and I are employing, I don't see any great advantage in employing a much more expensive MPPT controller. From what I've read, the PWM controllers in both setups are time-tested and decent enough controllers. Sure, MPPT controllers are better and I'm not familiar with setup enough to know if there is a diode to prevent draining batts when darkness comes, but I can always jerk the cord if it becomes an issue. There are Pros and Cons to each controller type, I encourage the OP to google it and choose what your budget will allow.
