The solar micro inverter system based on renewable energy is becoming increasingly popular among consumers. Each system unit operates with only tens of volts of DC voltage and is connected in parallel, which minimizes potential safety hazards. Renesas provides high-performance MCU alongside all other key power and analog devices.

System Benefits:

  • 240MHz MCU uses high-resolution PWM to achieve high precision control on DC/DC and DC/AC conversions.
  • MOSFETs and drivers ensure high-efficiency power device operation.
  • Optical coupled isolation amplifier protects low-voltage devices from damage caused by high-voltage devices.




  • Solar power system
  • Energy storage
