Applications/Uses

Description

The MAX20801 family of Cell-String Optimizers enables cell-string Maximum Power Point Tracking (MPPT), providing superior photovoltaic (PV) module energy harvest and reliability as compared to both standard panels and those incorporating module level MPPT technologies.

Photovoltaic cells can only deliver maximum power under specific electrical conditions that vary significantly with exposed irradiance and temperature. Series connections of PV cells creates a significant sensitivity to cell mismatch, resulting in less than optimal power and energy production under real-world conditions. The MAX20801 Cell-String Optimizer enables a string of PV cells to deliver their collective maximum power into a wide range of load conditions. This enhanced electrical flexibility eliminates power loss from mismatch in PV strings and arrays, ultimately improving energy production and system design flexibility.

Additional unique advantages provided by the Cell-String Optimizers:
  • Reduction in performance degradation over the PV module operating lifetime
  • Elimination of high losses associated with bypass diode conduction
  • Limit the operating voltage of the PV module
