Efficient effect
The function of a solar grid connected inverter is to convert the direct current (DC) generated by solar panels into alternating current (AC), thereby rendering it compatible to be plugged into the grid and integrated into the power system. Inverters not only ensure the conversion efficiency of current, but also monitor and ensure the safety of the system, against overload, overvoltage and other faults, and ensure the stable operation of solar power generation systems. In addition, the inverter can also adjust the output power to ensure synchronization with the grid and improve the energy utilization efficiency of the entire system
