1. Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%

2. Full digital technology, high charge conversion efficiency up to 98%

3. LCD display design, read operating data and working condition easily.

4. Real-time energy statistics function.

5. 12/24V automatic recognition

6. Liquid,Gel,AGM and Lithium battery for selection

7. External temperature sensor, automatic temperature compensation

8. Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise

9. Four stages charge way: MPPT, boost, equalization, float With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the rated current, the controller will lower the charging power, which enables the system to work under the rated charging current

10. Multiple load control modes: Always on, Dusk to Dawn, Evening, Manual

11. Support Android mobile phone APP,realize wireless monitoring function of solar controller.
