The working principle of inverters (solar inverters) is mainly to convert the direct current (DC) generated by batteries (including solar panels) into alternating current (AC) to supply household and commercial electricity or integrate into the grid. The main control chip adjusts the voltage and frequency by controlling the switching frequency and duty cycle of the switching components, ensuring that the output AC power meets the requirements of the power grid. Usually equipped with MPPT function and communication protocol with batteries (such as BMS), some can also maintain contact with mobile phones and other devices through wireless communication (such as WIFI) to monitor the working status of the system at any time.
