Application Note

Solar Energy Data Recording and Remote Monitoring

Overview

MW100 records solar power parameters such as radiance, ambient temperature and before/after electric conversion power data.

Application keys

  • Solar module data (temperature, DC current/voltage) before electric conversion can be recorded via JUXTA (converter)
  • Power data after electric conversion using power meter record by communication (digital data can be more accurate). Some inverters have direct Modbus output.
  • Panel efficiency calculation from measurements in math channels

Benefits of using MW100

  • On-demand data recording/monitoring
    Data recorded simultaneously to CF and network (OPC).
  • Continuous data recording
    Even after power failure recovery failure, MW100 continues to record data.
  • Sum of power data display
    Displays the integral value for each channel
  • Operates in harsh environment (-20 to 60°C)
