Morningstar Corporation SunSaver 20A PWM Solar Charge Controller 12V Batteries LVD, Solar Panel Controller Battery Controller Solar Controller 12V, Lowest Fail Rate Charge Controllers for Solar Panels

I use this device with a 200W solar panel system (and batteries) in one of my animal barns. It's the second one I have purchased; not because one went bad, but because it WORKS. I've had other ones die on me in only a year of use.

I have heard nothing but good about this piece of equipment. I have not yet used it but looking forward to installing it when I set up my system. I was sorry to see it is imported and not made in the USA. I hope it is still a high quality device. Time will tell.

This was too large for my application, and was very heavy. I had researched this device literally since 2006, and know it's quality is legendary.I went with a cheaper charge controller that had a digital display and 2 USB charging ports too.Would not buy for a hobby solar project. This would be fine for permanent installation at a remote camp or in an RV.

Very efficient pwm charge controller. Industrial grade and gives the peace of mind its will function no matter what.

I didn't understand what a 'flooded battery' meant.The controller went into a loop and wouldn't charge. After reading the directions, I removed a jumper and now it works fine. Who reads directions? Ha. RT
