When you use solar panel through grid tie inverter, your home power meter will reduce the speed(if you are using other electric appliances), or your home power meter will backward(if you are not use any appliances). The inverter can be connected to any outlet at home, when this line run by the conventional electric network. The inverter IC will monitors the volume, frequency and phase of the home grid, then produce a pure sine wave that the frequency and phase will be match the grid’s, and the volume will be higher than the grid’s, then according to our current controlled PWM, to control the output power to the grid. The inverter will puts out power when the home grid is on. Traditional grid tie inverter is the solar panel are connect in series, so if one solar panel did not work or bad efficiency, then the whole system will be effects, but power jack grid tie inverter, you can use every inverter in parallel, in this moment, each inverter has it’s own MPPT, can make every solar panel got the max power. Our grid tie inverter has 3greens light, when the charge fucntion is normal, then this 3lights will turn on, but if there are not dc sources(like in the night, no sun shine or raining day), the red led light will turn on, the inverter will stop to work, in this moment, the inverter will close the door, the home grid power will not back to inverter. When you set up the grid tie inverter. Pls put the AC plug first. After plug into the home ac source. Dont remove the plug anymore. Otherwise it may have hight voltage spikes. Then connect the DC input. When you want remove the grid tie inverter. Please take away the DC input first. Then you can remove the AC plug.
