Feature:   1. Highest Power Point: Optimize the output power of each solar panel, so that the solar panel can get the highest power point tracing and reduce the shading effect caused by obstacles.     2. Reduce Electrocution Possibility: The input voltage and start up voltage are low, usually within DC18 to 60V, which can better defend the use and security of the inverter and system, and reduce the possibility of electrocution.     3. Multiple Protection: This micro inverter has over voltage protection, under voltage protection, over frequency protection, under frequency protection, over current protection, etc.     4. Expanding Installed Capacity: Using micro inverter can expand the installed capacity of the system based on the origin solar system without replacing the inverter.     5. Cooling Method: Our micro inverter adopts natural heat dissipation, which can support indoor and outdoor work, and is applicable to a wide range of applications.             Specification:                       Item Type: MPPT Solar Inverter  Material: Aluminum alloy, red copper  Output Voltage: 90-130V  DC Input  Recommended Solar Panel Input Power: 200-300W x 2  Number of DC Input Connection Groups: 2  Maximum DC Input Voltage: 52V  Operating Voltage Range: 20-50V  Starting Voltage: 18V  MPPT Tracing Range: 22-48V  MPPT Tracing Accuracy: >99.5%   Maximum DC Input Current: 12A x 2  AC Output  Maximum Output Power: 600W  Rated Output Voltage: 120V  Output Voltage Range: 90-130V   Rated AC Current(at 120V): 5A  Rated Output Frequency: 50Hz  Output Frequency Range: 47.5 to 50.5Hz  Total Harmonic Distortion Power Factor: <5%   Maximum Number of Branches Connected: 120V, 5  Maximum Conversion Efficiency: 95%   CEC Efficiency: 92%  Nighttime Loss: & 65308;80MW  Overvoltage or Undervoltage Protection: Yes  Over or Under Frequency Protection: Yes  Antislanding Protection: Yes  Overcurrent Protection: Yes  Overload Protection: Yes  Overtemperature Protection: Yes  Protection Grade: IP65  Operating Ambient Temperature: -40°C to +65°C  Number of Indicator Lights: 1 working status LED and 1 Wifi signal light  Communication Connection: WiFi 2.4G   Cooling Method: Natural cooling (no fan)  Working Environment: Indoor and outdoor  Certification Standards: For ENG1000 3 2, for EN61000 3 3.
