Specifications:  Grid Tie Inverter Maximum Output Power:120/150/180/260/300/350W/500W/600W/700W.  DC Input: 10.5V-60V.  Output Voltage: 110V/220V.  Frequency Range: 50/60HZ.  Auto MPPT range: 28V - 55V.  Solar Panel Power: maximum 120/150/180/260/300/350W/500W/600W/700W.     Notice:  Use solar panel ONLY connect to this equipment.  This equipment is ON-GRID Microinverter, To make it work properly, it must be connected to the power grid correctly,and the power grid is working properly, When the power grid stopped working, it will also stop generating.  Do NOT exceed PV panel(s) voltage over the inverter max input voltage.（Voc＜60V） Do NOT exceed PV panel(s) power over the inverter max input power.  The positive and negative poles of the solar panel cannot be reversed. If you extend the solar panel cable. You need to be careful about this problem.  Install away from direct sunlight and direct rain exposure.(Ventilated, dry, cool).  LED DISPLAY:  1.Green light steady=Microinverter in generating.  2.Red flash=Microinverter in waiting.  3.Red light steady= a.Island protection. b.Over-temperature protection. c.Over/low AC voltage protection. d.Over/low DC voltage protection. e.Over/low AC frequency protection. f.Fault.     Package Include:  1 x Grid Tie Inverter.  1 x AC Cable 30CM.  1 x English User's Manaul
