  • Sunshine Grid Tie Power Inverter is the world’s most technologically advanced inverter for use in utility-interactive applications. This manual details the safe installation and operation of the Sunshine Grid Tie Inverter With Limiter. This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation, and management. The small type wind grid tie power inverter can obtain the wind energy from wind turbine and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable.
  • We call the system combined with a small Grid Tie Inverter With Limiter and wind turbine ‘SGWT’. The system includes a wind turbine and small grid tie inverter and installation kit, and some “SGWT” also will include controller, dump load resistor.
  • The inverter can be connected to any outlet of the utility grid at the house. The small grid tie inverter monitors the volume, frequency, and phase of the home utility grid, then produce pure sine wave AC power 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 wind turbine is rotating, and the output of the voltage is in the range of the rated input voltage of the inverter, the wind turbine will produce power, and the Grid Tie Inverter With Limiter will change the power from the wind turbine to the home grid. When the total power of the electric apparatus that is used in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, which will slow down the power meter, otherwise, the difference in the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid.

Grid Tie Inverter With Limiter Installation Procedure

Installing Sunshine Grid Tie Power System involves several key steps:

  1. Considering the total capacity of the grid-tie power system that you need.
  2. Choosing an applicable wind turbine for Sunshine Grid Tie Inverter.
  3. Selecting accessory for installation of the Grid Tie Power System.
  4. Selecting the correct model of Sunshine Grid Tie Inverter.
  5. Installing wind turbines in suitable places.
  6. Installing Sunshine Grid Tie Inverter to a suitable place.
  7. Connecting Sunshine Grid Tie Power System with cables and connectors.
  8. Grounding the system.

Each of the detailed installation steps in the following sections is numerically referenced in the installation diagram below.

Step1. 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 you want it to feed to the utility grid. Actually, the volume is just according to your will, 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, this 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.

If you use a 1KW wind turbine, then we call the “GTWT” system is 1KW grid tie power system, of course, you can install a 500W grid tie power system or 2KW grid-tie inverter, Grid Tie Inverter With Limitereven more, large capacity or more small capacity grid-tie inverter, it doesn’t matter. But if the capacity is too big, you should consider the volume of AC system of your house can hold the fed power.

Step2. Choosing Applicable Wind Turbine For Sunshine Grid Tie Inverter


Description of Wind Turbine

  • A wind turbine is a device that converts kinetic energy from the wind into electrical power. A wind turbine used for charging batteries may be referred to as a wind charger, a wind turbine also can connect to a grid-tie inverter for wind turbine like SUN WAL or WDL series grid tie inverter to feed energy to utility gird.
  • The result of over a millennium of windmill development and modern engineering, today's wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs. Slightly larger turbines can be used for making small contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels.
  • A quantitative measure of the wind energy available at any location is called the Wind Power Density (WPD) It is a calculation of the mean annual power available per square meter of the swept area of a turbine, and is tabulated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density. Color-coded maps are prepared for a particular area described, for example, as "Mean Annual Power Density at 50 Metres". In the United States, the results of the above calculation are included in an index developed by the National Renewable Energy Laboratory and referred to as "NREL CLASS". The larger the WPD calculation, the higher it is rated by class. Classes range from Class 1 (200 watts per square meter or less at 50m altitude) to Class 7 (800 to 2000 watts per square m). Commercial wind farms generally are sited in Class 3 or higher areas, although isolated points in an otherwise Class 1 area may be practical to exploit.

Most wind turbines have a similar curve of wind speed to power, pig2 is a typical curve of wind speed to power of 1000W wind turbine

SUN series grid-tie inverters for the wind turbines are suitable for wind turbines their rated power is from 200W to 2000W.

Choosing Wind Turbine

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

Step3. Selecting Accessory for Grid Tie Power System installation.

The accessory for grid-tie power system include:

  1. Connecting cables will be connected with wind turbines and inverters.
  2. Connectors.
  3. AC cables.
  4. Power meter(Optional).
  5. Bracket for wind turbine installation(not included in this user manual).

Selecting connecting cables

Before you connect a wind turbine to a SUN series grid-tie inverter, a suitable specification of cables should be selected. The selection of specifications of the cables is according to the max. power(Pmax.) and the rated DC voltage(Vdc) of the wind turbine.

You should calculate the maximum current(Imax) that will transit through the cables, we mark it as Imax. First, calculate the Pmax of the wind turbine, maybe some factories just submit the rated power(P) of their wind turbines, if so, you can estimate the Pmax, just multiply 1.5 (Pmax = P*1.5). we can get the Imax using formula (1) shown below.

Imax = Pmax/Vdc ------ (1)

After finishing the calculation of Imax, then we can pick suitable cables according to Table 3. It’s best that you choose cables for outdoor use.

If the wind turbine is AC output type, then you can choose thinner cables then you get the result according to formula(1).

Selecting Connectors

When installing the SGWT system, maybe you should use some connectors for connecting the wind turbine and inverter, be sure that the connectors must hold the Imax.

Selecting AC cables

AC cables will be supplied with inverters by our factory, different countries will be supplied different type AC cables, according to the standard of the area. You should provide the information to the dealer where you will install the system.

Step4. Selecting Correct Model of Sunshine Grid Tie Inverter.

When finished step1 to step3, then you can select the correct model of the 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 the 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 Table 3: American Wire Gauge (AWG)

Cables / Conductor Sizes and Properties DC input range of the grid-tie inverter.

Step5. Installing Wind Turbine to the suitable place.

Installing the wind turbine of the “SGWT” to a suitable location where the wind is strong enough to drive the wind turbine.

Warning: Please read the user manual of wind turbines before you install the wind turbine, don’t install the wind turbine under high wind.

Warning: Ensure using a strong bracket 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

Step6. Installing Sunshine Grid Tie Inverter to a suitable place.

Place the Sunshine 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.

Step7. Connecting the Sunshine Grid Tie Power System with Cables and Connectors

After finishing from Step1 to Step6, you should connect the wind turbine and inverter with cables and connectors to integrate the Sunshine Grid-Tie System.

Step8. 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 connected to the housing of the inverter when the AC cables are connected to the inverters, so when the AC plug is inserted into the socket of the AC outlet of the utility grid in the house, the ground pin of the socket must be connected to the Earth ground.

Step9. Connecting the wind turbine output cables after completion from Step1 to Step8.

Warning: Before connecting the wind turbine output cables to the grid-tie inverter, you should stop the rotating of the wind turbine just in order to avoid the sparkle when connecting the cables.

You can get more information from the attachment.
