Microchip Grid Connected Solar Micro Inverter Reference Design

Microchip Technology unveiled a reference design for a fully digitally controlled Grid-Connected Solar Micro Inverter. The reference design connects to any standard solar panel and converts the panel’s DC output into AC power, which can then be fed into the public power grid. In a real-world application, multiple units can be connected together to achieve the desired power output. The free reference design includes complete documentation, software, schematics and application note.
