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.
The digital signal controller (DSP) 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.
Solar power inverters process the electricity produced by a solar power system to make it suitable for meeting the specific demands of the load. It is extremely important to match the capabilities of these devices with the characteristics of the equipment that will be using the power. Major design considerations for inverters include their capacity, voltage rating and battery capability.
Solar inverters modify the current and voltage provided by the solar energy panels to maximize electric power output. They convert DC power from the panels to AC power usable by most business and home devices and they match the converted AC power to the voltage and frequency of the utility's electrical network.
