This charge controller was never used and is still new in the original package. It can be used for 12 Volt or 24 volt systems. The rating is 1000 watts of panels if you have a 12 volt system. If your solar system is set up for 24 volts you can use up to 2000 watts of panels.
It has a display that shows your battery voltage and how many amps are coming in from the panels. You can adjust the setting for how many volts you want your batteries to charge up to.
