The solar inverter is a critical component in a solar energy system. It performs the conversion of the variable DC output of the Photovoltaic (PV) module(s) into a clean sinusoidal 50Hz AC current that is then applied directly to the commercial electrical grid or to a local, off-grid electrical network. In our inverter main heart is a real-time microcontroller. The controller executes the very precise algorithms required to invert the DC voltage generated by the solar module into AC. This controller is programmed to perform the control loops necessary for all the power management functions necessary including DC/AC. The controller contains advanced peripherals like high precision PWM outputs and ADCs for implementing control loops. The ADC measures variables, such as current, battery voltage and then adjusts the DC/AC converter by changing the PWM duty cycle. In our inverter we adjust the PWM within a single clock cycle, so real time control is possible.
