Features:1Main Function: Solar micro inverter is a device that converts solar panels from DC to AC with a small size and capacity and is often used in small solar systems. 2Grid Tie: This device is a grid tie micro inverter. To make it work properly it must be connected to the grid properly and the grid works properly and when the grid stops working it will also stop generating electricity. 3Safrty Use: The positive and negative poles of the solar panel cannot be reversed. If you extend the solar panel cable you need to be careful about this problem. 4Installation Notes: Install away from direct sunlight and direct rain exposure. Please keep it in a ventilated dry and cool place. The voltage of the PV panel should not exceed the maximum input voltage of the solar grid tie inverter.
