A photovoltaic inverter is a device used to convert the direct current generated by photovoltaic panels (solar panels) into alternating current. Photovoltaic panels can convert sunlight into direct current, while photovoltaic inverters convert this direct current into the alternating current we use in our daily lives for use in households, industries, and businesses.
The main functions of photovoltaic inverters are as follows:
- Electricity conversion: Convert the direct current output from solar panels into alternating current to meet the power supply needs of the grid. AC power is the form of electrical energy used in our daily life and industrial production.
- Grid connected injection: For photovoltaic systems connected to the grid, photovoltaic inverters can inject excess electricity into the grid to reduce dependence on the grid and obtain certain grid connected benefits.
- Energy management: Photovoltaic inverters usually have the function of monitoring and managing photovoltaic systems, which can monitor the status, current, voltage and other information of photovoltaic panels in real time, and provide users with monitoring and optimization of the performance of photovoltaic systems.
- Protection function: Photovoltaic inverters usually have overload protection, short circuit protection, overvoltage protection, undervoltage protection and other functions to ensure the safe operation of the photovoltaic system.
In summary, photovoltaic inverters play a crucial role in photovoltaic power generation systems, converting light energy into practical alternating current, enabling solar energy to be used for power supply and grid integration, achieving sustainable development and energy conservation and emission reduction goals.
