SUN Series Grid Tie Power Inverter

 

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.

 

u  ADVANTAGE

There are many advantages of SGPV compare with the traditional grid tie system.

1. Low cost and easy installation - SGPV can make full use of all types of buildings’ surface that face to the sun in the city as well as fast and easy installation of solar modules and grid tie inverter. It's very low maintenance costs.

2. Free combination - SGPV can be used as a separate grid tie system and can be setup as a large solar array with many of them. The quantity of SGPV in the array is just according to your desire. If you are planning to install a grid-tie PV system, in a general way, the solar array and inverter need to be carefully matched to ensure that the inverter’s voltage and power limits are not exceeded. When you want to increase more solar panels, and if the total power of the solar panels exceeds the allocation grid inverter, it is necessary to increase the cost of a grid inverter.

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

 

u  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 40A. 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~1000W.

2, Connect the supplied AC power cord to the inverter and plug it to a home wall socket.

3, 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, this is called “Island Protection”.
