Features:      1. Made of high quality material, durable and long service life.      2. Adopt LED display mode, this inverter has power indication, voltage indication, ac frequency indication and overvoltage indication      3. The direct current can be converted into alternating current, and the output alternating current can be synchronized with the frequency and phase of the mains, so the output alternating current can be returned to the mains      4. High stability and it has output short circuit protecting function      5. Commonly used in some DC voltage sources (such as solar panels or small wind turbines) and grid connection applications             Specification:      Condition: 100% Brand New                      Waterproof Grid-Connected Inverter Series           WVC600-120V/60Hz                     Recommended Solar Panel           600W/Vmp>34V/Voc<50V                     Photovoltaic Maximum DC Input Current           40A                     Maximum Ac Output Power           600Watt                     Maximum Dc Open Input Voltage           50VDC                     DC Input Voltage Range           22 ~ 50VDC                     Maximum Output Power Factor           0.99                     DC Input Back Pressure Protecting           FUSE                     AC Output Voltage Range           80V125V160V                     AC Frequency Range           45 50 54Hz                     Output Total Harmonic Distortion           THDIAC<5%                     AC Phase Difference           <0.
