Features: 1Small in Size: The solar micro inverter is a device that converts the direct current of the solar panel into alternating current. It is small in size and capacity and is often used in small solar energy systems. 2Work: This device is a grid micro inverter. To make it work normally it must be connected to the grid normally. The grid works normally. When the grid stops working it will also stop generating electricity. 3Installation: You should avoid direct sunlight and rain during installation and keep it ventilated dry and cool and it is made of premium aluminium alloy material that is durable. 4Photovoltaic Panel Voltage: The voltage of the photovoltaic panel should not exceed the maximum input voltage of the solar grid inverter. 5Note: If you extend the solar panel cable you should pay attention that the positive and negative poles of the solar panel cannot be reversed.
