Magic series solar controller is based on an advanced maximum power point tracking (MPPT) technology developed, dedicated to the solar system, the controller conversion efficiency up to 98%.
It comes with a number of outstanding features, such as:
  1. A combination of multiple tracking algorithms enables tracking the maximum power point quickly and accurately
  2. Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%
  3. Full digital technology, high charge conversion efficiency up to 98%
  4. LCD display design, read operating data and working condition easily
  5. Flexible System battery selection: Liquid, Gel, AGM and Lithium
  6. Extends battery life through accurate remote temperature sensor
  7. The Controller is protected against over-temperature due to built-in power reduction function
  8. Four stages battery charging process: MPPT, boost, equalization, float
  9. Dual automatic protection to avoid exceeding the rated charging power and current
  10. Multiple load control modes: Always on, Street lamp, User-defind Mode
  11. IOT Wireless communication or Bluetooth communication functions optional
  12. With the wireless communication function of the IOT , the controller can be connected remotely through IoT/GPRS
  13. Monthly charging data can be calculated and displayed by grouping and graphs
  14. Based RS-485 standard Modbus protocol with RJ11 interface to maximize the communication needs of different occasions.
  15. Full automatic electronic protect function for increased charge controller availability
