Feature: 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.

Package List: 1 x Inverter1 x User Manual 1 x Connector1 x Screw Pack Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.1. The product can not work in the state of high power for a long time, the higher the power, the faster the heating.2. When the temperature of the shell reaches 65 degrees, it will enter the high temperature protection state. You can open the shell and blow the heat sink (aluminum block) and transformer on the circuit board of the machine with the fan. You can solve the problem of over‑temperature protection.3. Note that the air flow is smooth, and it needs to be away from objects susceptible to high temperature.4, the inverter input and output conversion efficiency is 80%, the greater the input power, the greater the output power, the highest output power is 400W.
