MPPT (Maximum Power Point Tracking) is a power electronic technology that improves the power generation efficiency of the system by monitoring the maximum power point of the solar inverter system power generation panel. In contrast, PWM (Pulse-Width Modulation) is a different power electronics technology, which converts the direct current output from the solar panel into a pulsed signal and adjusts the power to a controllable level to control and regulate the output of the device voltage and current.

Solar inverter not only has the function of DC-AC conversion but also the function of maximizing the performance of solar cells and the function of system failure protection. In short, there are automatic operate and shutdown functions, maximum power tracking control function, anti-private operation function (for the grid-connected systems), automatic voltage regulation function (for the grid-connected system), DC detection function - grid-connected (for the grid-connected system) systems) - connection system) and DC ground detection. Function (for the grid-connected system). We mainly introduce the automatic operation and shutdown function and the maximum power tracking control function of the Solar inverter.

Why we need a solar system and what we need to set it up?Recently, a growing number of people have started to utilize solar power in their homes, because solar energy is a renewable, eco-friendly alternative to traditional electrical systems. The value of solar energy around the world will increase

The history of solar energy can be traced back to the 7th century BC when people used magnifying glasses to make fires. Today, you can find solar power all over the world, from the US to Italy to Japan. Solar prices have continued to decline over the years as production has increased.

Sunlight illuminates the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p- n junction electric field, the holes flow from the n region to the p region, and the electrons flow from the p region to the n region. After the circuit is turned on, a current is formed.
