Solar power optimizer

Block diagram

Overview

A solar power optimizer is a module-level power electronic that optimizes power output and increases efficiency. Our integrated circuits and reference designs help you create solar power optimizers that improve power density and efficiency and enable real-time communication and monitoring.

Design requirements

Solar power optimizer designs often require:

  • High-power conversion efficiency to reduce self-heating.
  • Accurate analog measurement of voltage and current.
  • Real-time communication and monitoring.
  • Long system lifespan and reliability.
