NTRODUCTION

The small type solar grid tie power inverter can 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 convenient and reliable.

We call the system combining with small solar grid tie power inverter and solar panels as "SGPV". The system includes solar panels and small type grid tie power inverter. Solar panels can be mono silicon, polygon silicon, non-crystal film or any other material that can transform solar energy to electric energy. The power of grid tie inverter should be matched to the power of solar panels connected. So the power of SGPV is defined by its solar panels, it can be standardization according to the actual using.

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 volume, 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 volume 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.

INSTALLATION

The individual system of SGPV is shown in Figure 1. Installing the solar panel of the SGPV at a suitable location that sunshine can irradiate on it, connecting the cables of the solar panel to the DC input terminals of the small grid tie inverter of the SGPV, inserting the plug of the inverter into the socket of the home grid. After this, when the sun shines, the SGPV will convert the solar energy to the home grid.

SGPV can be stackable, and all SGPVs are independent each other. The total power converting to the grid is the total power of all SGPVs. The installation of each SGPV is same. Connecting large quantity of SGPV to the grid, this will construct high-power grid-tie system.

Operation Procedures
1.Connect the Solar Panel or Wind Turbine?s DC supply cables to the DC input terminal of the inverter, be sure that the polarity is correct. Recommended DC input cable size for maximum output is 8AWG or cables that can handle more than 30A. Optimal length would be less than 8m, longer cables will experience higher voltage drop. The range of output power of Solar Panel or Wind Turbine is 20W~250W.
2.Put the AC output voltage switch on the inverter to the correct position (115V or 230V) according to your location home grid AC voltage.
3.Connect the supplied AC power cord to the inverter and plug it to a home wall socket.
4.The 3 green LED indicators will start to cycle from left to right when the grid and DC supply is detected. This indicates the inverter is operating under normal condition. The rate of the cycling is according to how much power is being output from the solar panels or the wind turbine. The more big output power is, the more fast the rate is. If there is no AC grid detected, the red LED will be on, the inverter will not put out power, and this is called ?Island Protection?.
