 Grid Tie Inverter 250 Watt  / 240 Volt                                        Grid Tie Inverter 500 Watt

The small type solar grid tie power inverter  obtain the solar energy from solar panel, and can tie to the grid through its output cable with no extra equipment. 

    The installation is very simple and reliable.

The inverter can be connected to any outlet at home, when this line run by the conventional electric network. The small grid tie monitors the Voltage, frequency and phase of the home grid, then produce a pure sine wave that the frequency and phase are as same as the grid's, and the Voltage is a bit higher than the grid's, then according to the current controlled PWM, to control the output power to the grid. The small grid tie inverter just puts out power when the home grid is on.

 When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid. When the total power of electric apparatus that are using in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, this will slow down the power meter, otherwise, the difference of the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid, this will make the power meter backwards.
