Y&H 2000W Wind Power Grid Tie Inverter With Limiter Sensor,Dump Load,45-90VDC 230VAC For AC 48V Wind Turbine Generator
The test point should be at the DC side of the built-in rectifier of the inverter, but you can calculate from 3 phases of AC output voltage of the wind turbine to get the DC voltage, the formula is Vac = Vdc/1.732. For example, if the DC input voltage range of the inverter is 45~90V, then the wind turbine's output AC range of the should be 45/1.732~90/1.732 = AC25.9V~ 51.96V.
This model grid tie has designed for wind turbines that put out 3 phases AC voltage. It can maintain the rotating speed of the wind turbine and keep the voltage from the wind turbine always at the range of the rated range of the grid tie inverter. It also has a high voltage protection function, when the wind is too big, and the dump load controlling system can’t keep the output voltage from the wind turbine, the controller will disconnect itself from the wind turbine, so it is very safe to be used
Wind Grid Tie Inverter with Limiter Sensor, which can prevent excess power from going to the public grid.Select the internal limiter mode,inverter will work under limiter mode,output power of the inverter will be determined by load power.
The backlit LCD display gives you a clear picture of the inverter's operating status.all adjustable parameter.The status of errors will be displayed with red letters on the grid tie inverter LCD display.
Easy installation,Can be paralleled on AC side.Overload protection ,Anti-island protection,Short-circuit protection/Reverse polarity protection
Product Specifications
We call a system combining with a small grid tie inverter and a wind turbine as "SGWT". The small type of wind grid tie power inverter can obtain the wind energy from wind turbines and tie to the grid through its output cables with no extra equipment. Plug and Play.
The inverter can be connected to any outlets of the utility grid at the house. The small grid tie inverter monitors the volume, frequency, and phase of the home utility grid, producing pure sine wave AC power that the frequency and phase are the same as the grids. The small grid tie inverter puts out power when the home grid is on.When the AC wind turbine is rotating, and its 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 will change the power from the wind turbine to the home grid. When the total power of the electric appliance that is using in the house is larger than the output power of the inverters, this 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 appliance will go out from the house to the out grid.
NOTE: Any DC power input is prohibited.
The Advantage of Inverter:
1. Directly connect to three phase wind turbine（48V AC Wind Turbine Generator）
2. Plug and play, easy to install.
3.Can be paralleled on AC side
4.built-in dump Load controller
5.Support WIFI communication. (Need to purchase additional WIFI module)
6. Each inverter need to pass twice testing (20 hours) before leaving factory.
7.Overload protection,Anti-island protection,Short-circuit protection/Reverse polarity protection
8.Wind Turbine Voltage Range:AC25.9V~ 51.96V
How to choose the correct wind AC output voltage?
You can calculate from 3 phases of AC output voltage of the wind turbine to get the DC voltage, the formula is Vac = Vdc/1.732. For example, if the DC input voltage range of the inverter is 45~90V, then the wind turbine's output AC range of the should be 45/1.732~90/1.732 = AC25.9V~ 51.96V.
Built-in dump Load controller:
This model grid tie has designed for wind turbines that put out 3 phases AC voltage. It can maintain the rotating speed of the wind turbine and keep the voltage from the wind turbine always at the range of the rated range of the grid tie inverter. It also has a high voltage protection function, when the wind is too big, and the dump load controlling system can’t keep the output voltage from the wind turbine, the controller will disconnect itself from the wind turbine, so it is very safe to be used.

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 applicable wind turbine for Sunshine Grid Tie Inverter.
3. Selecting accessory for installation of the Grid Tie Power System .
4. Selecting correct model of Sunshine Grid Tie Inverter.
5. Installing wind turbine to suitable place.
6. Installing Sunshine Grid Tie Inverter to suitable place.
7. Connecting Sunshine Grid Tie Power System with cables and connectors.
8. Grounding the system.
Three Phases Grid Tie Power System:
For example, installing a 6KW grid tie power system to three phase utility grid.The diagram is shown in Fig. 8, we seperate 6KW power sytem to three power system units,every unit has 2KW power. Connecting every system unit to different phase, this canbalance all grid tie power to three phases of the utility grid.Fllow this way, you can install more large grid tie power system to three phases, justseperate the whole power system to three equal power system units
