Design Considerations

Solar Power Inverter:

The solar inverter is a critical component of an entire solar energy system. It performs the conversion of the variable DC output of the PV cells into a clean sinusoidal 50- or 60 Hz current suitable for supplying the commercial electrical grid or local electrical network.

DSP Controller - The digital signal controller effectively executes the very precise algorithms required to charge the battery of the system and provide power to the electrical grid without power losses. This is called executing the system at its maximum power point. The drive of the main bridge of the DC/AC is performed by highly flexible PWM peripherals of the controller.
