Reference Design for Voltage, Current & Temp Monitoring for Solar Module Level Power Electronics


Design files


The TIDA-00640 verified reference design provides an overview on how to implement a solar module level monitoring and communication sub-system. This design addresses the key need of a highly cost optimized monitoring and communication sub-system for solar Module Level Power Electronics (MLPE). This design showcases a highly integrated solution for accurate voltage, current and temperature monitoring along with ZigBee communication using CC2538 to enable Solar Module level monitoring. 

  • <2% voltage measurement error
  • <2.5% current measurement error
  • CC2538 M3 SoC for ZigBee communication
  • PCB based antenna with simplified filtering circuitry
