1、[Working Principle] Solar micro inverter is a device that converts solar panel DC into AC, with small size and capacity, commonly used in small solar system. 2、[Usage Requirements] To make the grid tie micro inverter work properly, it must be connected to the grid normally, and when the grid stops working, it will also stop generating electricity. 3、[Positive And Negative Ends] The positive and negative ends of the solar panel should not be connected backwards. If you extend the solar panel cable, you should be careful about this issue. 4、[Installation Environment] This microinverter supports IP55 protection rating, but it should be installed to avoid direct sunlight and rain, and placed in ventilated, dry and cool conditions. 5、[Voltage Requirement] To ensure normal operation, the voltage of the PV panel should not exceed the maximum input voltage of the solar grid tie inverter (Voc<50V). 1 x Micro Inverter1 x Instruction Manual1 x AC Cable Item Type: Micro InverterMaterial: Aluminum AlloyProduct Size: Approx. 22.7 x 7.7 x 3.7cm / 8.9 x 3 x 1.5inGross Weight: Approx. 552g/ 2.0ozPhotovoltaic OutputNumber of Connectors At Input: 1set (Group)Maximum Power Point Tracking Range: 24V-40V Operating Voltage Range: 18V-50V Maximum DC Input Voltage: 50V Starting Voltage: 18V AC Output (AC)Single Phase Grid Type: 120V, 230V Rated AC Voltage: 120VAC, 230VAC Output Voltage Range: 120VAC: 80V-160V 230VAC: 180V-280V Rated AC Frequency: 50Hz, 60HzOutput Frequency Range: 50Hz: 47.5Hz- 52.5Hz, 60Hz: 57.5Hz- 62.5Hz Output Power Factor: > 0.99EfficiencyMaximum Conversion Efficiency: 92.5%CEC Weighted Efficiency: 120VAC: 90.5%, 230VAC: 91.5%Tracking Efficiency: 99.9%Nighttime Loss: <700mWMechanical DataOperating Ambient Temperature: -40℃ to +65℃Storage Ambient Temperature: -40℃ to +85℃Protection Level: IP55Cooling Method: Natural Cooling, No FanOther FeaturesIsolation Characteristics: High Frequency Transformer IsolationComprehensive Grounding: PE end in AC cable line is the grounding wire of the equipment, no other grounding port.Protection Mode: Islanding Protection, Voltage Protection, Frequency Protection, Temperature Protection, Current Protection, etc.
