Setting Operation:

There are two methods that can modify load mode and control parameter through infrared interface:

  • Romote meter, MT50
  • Super Parameter Programmer, SPP-02

This method can realize one-key setting operation with is suitable for bulk quantity products setting or applied in the projects.

  • PC monitoring setting software "Solar Station Monitor"
