Specification----------------------------------------------------------------------------This item Using IP65 waterproof streamline design, can effectively prevent rainwater on the surface erosion, built-in high-performance, maximum power point tracking (MPPT) function, better able to track changes in the solar iuminosity and control different output power. Effectively capture and collect sunlight. AC electric power transmission using the reverse transmission technology, is one of our patented technology. The inverter output power can provide load priority use, extra electricity to the grid. Efficient use of the inverter to the power emitted. Electricity transmission rate of up to 99%.Communication using two modes. Between the inverter and collector using wireless communication signals. Collector with a PC or other devices to communicate using RS232 serial port/ WIFI wireless communication. Intelligent monitoring systems, the inverter can collect real-time data, inverter can be controlled startup / shutdown / power regulation.Condition: 100% Brand NewItem Type: Photovoltaic Micro-inverteMaterial: Aluminum AlloyColor: GreySize: Approx. 37 x 30 x 4.16cm/ 14.6 x 11.8 x 1.6inchWeight: Approx. 3038g / 107.2ozParameter:1200W (wireless) parametersInput Data KD-WVC-1200 (wireless)-120VAC / 230VACMaximum Input Power: 1200WSolar Panel Power: 4 x 300W is recommended, open circuit voltage 36-50VOCSolar Panel Open Circuit Voltage Range: 36-50VOCPeak Power Tracking Voltage: 22-50VMinimum / Maximum Starting Voltage: 22-50VMaximum DC Short Circuit Current: 80AMaximum Input Current: 54.4AOutput Data: @ 120VAC @ 230VACPeak Power Output: 1200WRated Output Power: 1150WRated Output Current: 9.58A 5ARated Voltage Range: 80-160VAC 180-260VACRated Frequency Range: 47-52.5Hz / 57-62.5Hz 47-52.5Hz / 57-62.5HzPower Factor: > 99% > 99%Maximum Unit: 3PCS (single phase) 5PCS (single phase) per branch circuitOutput Efficiency: @ 120VAC @ 230VACStatic MPPT Efficiency: 99.5% 99.5%Maximum Output Efficiency: 95% 95%Night Power Consumption:
