Feature: 1. MAIN USE: Micro grid connected inverter is a compact unit that can directly convert direct current into alternating current, supply power to electrical or office equipment, and connect to the public power grid. The AC output of the micro inverter is synchronized and in phase with the public power grid. 2. WORKING PRINCIPLE: A solar micro inverter is a device that converts the direct current of a solar panel into alternating current. Small in size and capacity, commonly used in small solar systems. 3. PREMIUM CONVERSION RATE: The grid connected inverter has premium conversion efficiency, with a maximum conversion efficiency of 93%, improving usage efficiency. 4. EASY TO OPERATE: Grid tie inverter needs to be connected to the power grid to be used, making it simple and convenient for you to use. 5. ALUMINUM ALLOY MATERIAL: The micro inverter is made of aluminum alloy material, which is sturdy and durable, and can be used for a long time.

A Output Parameter: 230VAC Output Voltage Range: 180-280VAC . Package List: 1 x Inverter 1 x AC Cable 1 x Instructions 2 x Installation Screw 6 x Washer2 x Nut Note: 1. Only use solar panels to connect to this device. Cannot be used with batteries, please use with caution.2. This device is an ON GRID micro inverter. To ensure its normal operation, it must be properly connected to the power grid, and the power grid must work properly. When the power grid stops working, it will also stop generating electricity.3. The voltage of the photovoltaic panel shall not exceed the maximum input voltage of the inverter.4. Do not exceed the maximum input power of the inverter for the photovoltaic panel power.5. The positive and negative poles of the solar panel cannot be reversed. If you extend the solar panel cable. You need to be careful with this issue.6. Avoid direct sunlight and rainwater during installation. (ventilated, dry, cool).
