This verified reference design provides an overview onhow to implement a solar module level monitoring andcommunication subsystem. This TI Design addressesthe key need of a highly cost-optimized monitoring andcommunication subsystem for solar module levelpower electronics (MLPE). This design showcases ahighly integrated solution for accurate voltage, current,and temperature monitoring along with ZigBee?communication using the CC2538 to enable solarmodule level monitoring.

Module level power electronics (MLPEs) provide a very granular method of optimizing a solar system.Moving the maximum power point tracking (MPPT) or other power management services to the modulereduces the cost overhead on a system and enables a higher total system power output. However, itremoves some of the capability of monitoring string degradation because every module appears toperform optimally to an outside observer. The addition of integrated power measurement at each MLPEenables several additional features:

? Array performance metrics to evaluate instillation return on investment
? Mesh based power point tracking more efficient power conversion
? Module degradation information due to aging or soiling
? Module mismatch and instillation issue analysis

The TIDA-00640 integrates the voltage, current, and temperature measurement into a single system thatis able to be powered by the module itself and wireless communicate the data back to a central pointthrough a number of wireless standards. This TI Design enables quick integration of the measurement andwireless technology with MPLEs to make a full distributed power conversion system.
