The rise of emerging markets often means the birth of new opportunities. As a new energy, solar energy provides a new stage for battery manufacturing, power conversion and other related enterprises. As the current generated by photovoltaic power generation system is DC, but the civil power is mainly AC power supply, and solar power generation will eventually move to grid operation, which means that solar power generation must convert DC to AC through inverter to drive household appliances and other loads. Therefore, inverter plays an important role in solar power generation system.
The main function of the inverter is to transform the variable DC voltage input of the power supply into the interference free AC sine wave output, which can be used by the equipment and fed back to the power grid. In addition to AC / DC conversion, the inverter can perform other functions, such as disconnecting the circuit, avoiding circuit damage due to current surge, charging the battery, storing the use and performance of data, and tracking the maximum power point (MPPT), so as to improve the efficiency of power generation as much as possible.
