The MAX20800 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 MAX20800 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

Product Details

The MAX2080XXEVKIT# family of evaluation kits (EV kits) serve as a reference platform for evaluating the MAX20800 and MAX20801 maximum power point tracking (MPPT) ICs. These single-chip, integrated switching regulators provide an extremely compact, low cost, highly efficient, fast, accurate and reliable power delivery solution for photovoltaic (PV) modules. Refer to the MAX20800 and MAX20801 IC data sheets for more information.

The EV kit comprises a fully-assembled and tested PCB implementation of the MAX20800. Input and output connectors for three photovoltaic cell strings are included for flexibility and ease-of-use with standard 60 or 72-cell crystalline PV modules.
