What is an inverter?
An inverter is a device that converts direct current (DC) to alternating current (AC). It is widely used in various electrical appliances. An inverter consists of an inverter bridge, control logic, and filtering circuits.

It can convert DC energy (such as from batteries or storage batteries) into fixed-frequency and fixed-voltage or variable-frequency and variable-voltage alternating current, typically in the form of a 220V, 50Hz sine wave.

Inverters are widely used in various scenarios such as in households, industries, and automobiles, for example, to power air conditioners, home theaters, power tools, lighting, and other equipment.
In photovoltaic systems, the inverter plays a crucial role.
The photovoltaic inverter can convert the direct current generated by the photovoltaic cells into alternating current at the frequency of the power grid, for off-grid or grid-connected use.

It not only has the conversion function, but also possesses special functions such as maximum power point tracking and islanding effect protection. It is a key device in the photovoltaic power generation system.
