The inverter is an important part of the solar power system. Its main function is to convert the direct current (DC) generated by the solar panel into alternating current (AC) for use in homes, industries and commercial applications. The efficiency and stability of the inverter directly affect the efficiency and operating cost of the solar system.
The 3.3 kw solar inverter is medium-power conversion device. Its "3.3 KW" refers to its rated output power of 3.3 kw, which means that it can continuously output 3.3 kw of AC power, which is enough to meet the daily electricity needs of small and medium-sized commercial projects or homes.
