Wind Grid Tie Inverter Installation

1. Considering the total capacity of the grid tie power system that you need.

The total capacity of the whole grid tie power system is according to your power consumption in the site that you want to install, or how much power that you want it to feed to the utility grid. Actually, the volume is just according to your willingness, because when the total power of electric appliances that are being used in the installation site is larger than the output power of the grid tie power system, these power from the system will be consumed in the site, this will slow down the power meter, otherwise, the difference of the output power from the system between the total used power of the appliances will feed to the utility grid.

For example, if you want to install a grid tie power system in your house, you could decide the total power volume according to the total power the appliances that you use in your house, maybe the consumption of total energy in per day is about 5KWH, then you should realize the averaged speed of the wind in per day at your site, check the power to the speed of the wind curve from the specifications of the wind turbine, then you can estimate the average power that the wind turbine can generate, actually the real average power the wind turbine can generate at your side is not easy to estimate, you need to check the history data of the climate, because it will vary every day according to the climate, just assume a 1KW rated wind turbine is suitable for the grid tie power system that you plan to set, with this capacity of the system,it can supply all power consumption in whole year.

When grid tie power system is working, sometimes, there is extra power feed to utility grid if the power from the grid tie system is larger than the power consumed by the appliances in your house, and sometimes will not when it is not larger.

If you use a 1KW wind turbine, then we call the "GTWT" system is 1KW grid tie power system, of course, you can install 500W grid tie power system or 2KW grid tie inverter, even more large capacity or more small capacity grid tie inverter, it doesn't matter. But ifthe capacity is too big, you should consider the volume of AC system of your house can hold the feeded power.

2. Choosing applicable wind turbine for Sunshine Grid Tie Inverter.

The most kinds of specifications that the factories marked about the wind turbines:

1, Starting wind speed(m/s);

2, Cut-in wind speed(m/s);

3, Rated wind speed(m/s);

4, Rated power;

5, Max. power;

6, Safe wind speed(m/s);

7, Rated DC voltage.

You need to choose a wind turbine that the rated power can meet the power consumption for your using. When you choose a wind turbine, you also need to consider ahead what model gird tie inverter of SUN series you want to use. Wind turbines have two output type, one is AC output type, and another is DC output type, if the wind turbine is DC output type, it must be integrated with a rectifier. So if the wind turbine is AC output type, you should use WAL model of SUN series grid tie inverter, if the wind turbine is DC output type, then you should use WDL model of SUN series grid tie inverter.

3. Selecting accessory for installation of the Grid Tie Power System .

The accessory for grid tie power system including:
1, Connecting cables will be connected with wind turbine and inverters.
2, Connectors.
3, AC cables.
4, Power meter(Optional).
5, Bracket for wind turbine installation(not included in this user manual).

4. Selecting correct model of Sunshine Grid Tie Inverter.

When finished step1 to step3, then you can select a correct model of SUN series inverter. If the wind turbine is DC output type, then you should choose WDL model inverters, and the input DC voltage range of the inverter should fit the DC output voltage of the wind turbine, the rated power of the inverter should also fit the max. power of the wind turbine, and the AC output of the inverter should fit the standard of AC utility grid.
If the wind turbine is AC output type, then you should choose WAL model inverters. Most factories don't supply the AC rated voltage, just supply DC rated voltage, so our WAL also supply the DC input range, please check the DC rated voltage of wind turbine should fit the DC input range of the grid tie inverter.

5. Installing wind turbine to suitable place.

Installing the wind turbine of the "SGWT" to suitable location where the wind is strong enough to drive the wind turbine.
Warning: Please read the user manual of wind turbine before you install the wind turbine,don't install the wind turbine under high wind.
Warning: Ensure using strong braket to fix the wind turbine to avoid the danger under high wind.
Warning: The blades of the wind turbine should be taken down before the hurricane is coming.

6. Installing Sunshine Grid Tie Inverter to suitable place.

Place the Grid Tie Inverter on a surface protected from direct sunlight, high temperatures, and water. The inverter requires at least 150mm of clearance around itself for ventilation. The inverters are for indoor use, can't use at outdoor. You can use screws to fix the inverter to the surface, because some models of Sunshine grid tie inverter have fans on the bottom cover, so the surface should be flat.

7. Connecting Sunshine Grid Tie Power System with cables and connectors.

Connecting the Grid Tie Power System with Cables and Connectors After finished from Step1 to Step6, you should connect the wind turbine and inverter with cables and connectors to integrate the Sunshine Grid Tie System.

8. Grounding the system.

Connect the ground terminal of the wind turbine to the NEC approved AC grounding electrode.
Connect the grid tie inverters to the grounded racking using a grounding washer approved for the racking. The ground wire of the AC cables is connnected to the housing of inverter when the AC cables is connected to the inverters, so when the AC plug is inserted to the socket of AC outlet of utility grid in the house, the ground pin of the socket must be connected to the Earth ground.
Last. Connecting the wind turbine output cables after complete from Step1 to Step8.
