1、Make the solar panel get the highest power point tracking MPPT to reduce the occlusion effect caused by shadows and other obstacles, and improve work efficiency. 2、Usually the DC voltage is within 18‑60V, and a lower input voltage can better protect the use and safety of the inverter and the system. 3、Compared with the UHV voltage caused by the series connection of traditional inverters, the safety factor of the micro inverter has a unique advantage. 4、The capacity expansion of the solar system does not need to consider the rated capacity of the inverter, and the installation is more convenient. 5、The installation capacity of the system can be expanded on the basis of the original solar system without replacing the inverter.
