This little charger just works, and works.. Affordable, and reliable. ### ⭐ Review *by A***R on 25 August 2024* 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. ### ⭐⭐ Review *by S***N on 30 December 2024* 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. ## Frequently Bought Together - Morningstar Sunguard 4.5A PWM Solar Charge Controller (SG-4) - Intelligent Solar Panel Regulator.
