Features:  【Function】: This solar grid tie micro inverter is constant current, constant output power, and will not appear overload, overcurrent phenomenon.  【Safety protection】: When the mains power grid fails and the power grid fails, the grid tie inverter will automatically turn off the output. 【Stacked use】: In order to meet the requirements of higher power use, this micro grid tie inverter can be used in stacks.  【Monitor all the time】: Using wireless communication system, with mobile phone APP monitoring.  【Application】: The solar micro inverter is a device that converts the direct current of the solar panel into alternating current. The volume and capacity are small, and the capacity is usually 0.2-1.6KW. It is often used in small solar systems or solar panel balcony power station.     Specifications:  Material: Aluminum alloy + PCB board + various components.  Number of input connectors: 2 group.  MPPT maximum power point tracking voltage range: 30V-54V.  Operating voltage range: 22-60V.  Minimum starting voltage: 20V.  Maximum tributary input voltage: 60V.  AC output voltage: 120V/230V (automatic identification).  Operating temperature range: -40°C to +65°C.  Rated AC frequency: 50Hz.  Monitoring system: Mobile APP.  Output power factor: >0.99.  Total harmonic distortion rate of output current: THD <5%.  Maximum conversion efficiency: 95%.  MPPT tracking efficiency: 99.9%.  Waterproof grade: IP65.  Cooling method: Self-cooling.  Options:  Solar Micro Inverter :300W / 400W / 700W / 800W / 1200W / 600W.  Maximum DC input power:300W / 400W / 700W / 800W / 1200W / 600W.  Maximum DC input current: 13.7A / 18A / 2*14A / 2*18A / 4*12A / 4*14A.  Maximum output power: 300W / 400W / 700W / 800W / 1200W / 600W.  Rated AC current: 1.3A / 1.7A / 3.05A / 3.5A  / 5.22A / 6.95A.     Packing List:  1 * Inverter.  1 * Communication antenna.  2 Sets * Fixing screws.  1 * AC output line.  1 * Installation user manual
