"I am using this charge controller for a solar powered driveway gate application with a 50W pv panel.
Needed a bit more charging capacity as I am also running LED entrance lights over night.

Have had this installed for a little over a week, and so far so good. This controller seems to working well and is able to get the battery up to float voltage without issue. I am also using the load output to power the entrance lights, which can be set for dusk to dawn or on at dusk and off after a prescribed time.

Only gave the charger 4 stars as the LCD screen on it is very directional. Your view angle must be from slightly above to get a clear view. Unfortunately due to mounting limitations in my controller box, I am only able to view from slightly below the controller and it is very hard to read. However, this is only important for configuration and periodically checking operation.
Data sheet/manual was a bit hard to read, but manageable."

5 star rating for this solar charge controller. Digital display is very accurate and a must to know what condition your battery Bank is in. This unit is preset but you can also change settings for your preference. It has 2 USB ports for charging phones and also direct wiring for outside lighting etc. Fully programable or use straight out the box like me.
