The principle of solar photovoltaic power generation is a technology
that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface.
The key component of this technology is the solar cell.
The solar cells are packaged and protected in series to form a large area solar cell module
and then combined with a power controller or the like to form a photovoltaic power generation device.
The whole process is called a photovoltaic power generation system.
The photovoltaic power generation system consists of solar cell arrays, battery packs, charge and discharge controllers,
solar photovoltaic inverters, combiner boxes and other equipment
An inverter is a device that converts direct current to alternating current.
Solar cells will generate DC power in sunlight, and the DC power stored in the battery is also DC power. However, the DC power supply system has great limitations.
AC loads such as fluorescent lamps, TVs, refrigerators, and electric fans in daily life cannot be powered by DC power.
For photovoltaic power generation to be widely used in our daily life, inverters that can convert direct current into alternating current are indispensable.
As an important part of photovoltaic power generation,
the photovoltaic inverter is mainly used to convert the direct current generated by photovoltaic modules into alternating current.
The inverter not only has the function of DC-AC conversion,
but also has the function of maximizing the performance of the solar cell and the function of system fault protection.
