MAX20801 Cell-String Optimizers

Analog Devices MAX20801 Cell-String Optimizer enables cell-string Maximum Power Point Tracking (MPPT), providing superior photovoltaic (PV) module energy harvest. These devices are also more reliable than 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 create 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 a collective maximum power into a wide range of load conditions. This enhanced electrical flexibility eliminates power loss from a mismatch in PV strings and arrays, improving energy production and system design flexibility.
