I have used this product before and it worked great. was just replacing an old one. This one is defective and doesn’t work either. Not sure where quality control went.

Mine has never worked and it's unclear if it didn't work out of the box or there was an installation error. Note the instructions state a VERY specific battery / panel connection sequence that they advise must be followed or you can brick the device. The lack of any indicator or connection lights limit troubleshooting to multimeter based following a relatively complex instruction sheet. While I believe Morningstar makes a quality product, you can purchase a controller for less that offers LED and charging data. I'd look elsewhere before purchasing this product again.
