Solar design engineers are being challenged to optimize energy harvesting, reduce installation costs, and improve system reliability and efficiency while standardizing their designs.
Microchip today announced a digitally controlled, grid-connected solar micro inverter reference design. 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.
This reference design works with any photovoltaic (PV) panel that supplies a maximum 220 watts output, and it comes in two versions supporting either 110V or 220V power grids. Both versions of this reference design are implemented using a single dsPIC33F ‘GS’ digital-power digital signal controller (DSC), which provides digital control of the power-conversion and system-management functions.
