New Grid Tie Inverter for 3 Phase Wind Turbines. Built-in Dump Load Controller – three phase AC input from wind turbine – Single Phase AC to Grid (100V 110V 120V 220V 230V 240V) – Built-in Power Limit Function. About the Input Voltage. DC 22-65V or 45-90V The DC input range of the wind inverter, 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 4590V, then the wind turbine’s output AC range of the should be 45/1.73290/1.732 = AC 26V 52V. The wind inverter must work with 3 phase AC model wind turbine, there should be 3 wires from the wind turbine. Another way, if the wind turbine is used to charge 24v battery, please select 22-65V inverter. If the wind turbine is used to charge 48v battery, and the highest voltage low than 65v, please select 22-65V inverter. If the 48v wind turbine highest voltage over 65v, and low than 90v, please select 45-90V inverter. Advantage Features of the 2G Wind Power Grid Tie Inverter. The 2nd Generation grid tie inverter, new technical, Higher efficiency. Higher MPPT efficiency, Max 99% Multiple intelligent protection to ensure safe use. Directly connect to three phase wind turbine, without regulator Easy to install and easy to operate. The Electric meter will SLOW down. The 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. The inverter can be connected to any outlets of utility grid at 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 produces power, and the grid tie inverter will change the power from wind turbine 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. Why our grid tie inverters need limit function? — It is in response to the overwhelming clamor from our customers for a function that can control the amount of power that the grid tie inverters can generate. With this function, the inverters will just generate power that is not larger than the loads’ power even the inverters are connected with big power solar panel array, we call it “limit function”. Because in some countries, the producer pays for the excess power it gives to the distribution grid. This is because the electric power meter(the one provided by the electricity provider in the area) is not aware of the direction of power flow. In other words it only adds even if power is exported to the grid, thus, the consumer will be charged for power even if it is given to the grid, and this is the problem. Our SUN G2 series grid tie inverters are integrated this limit function, so SUN G2 series inverters can work in limit mode or normal mode(no limit), you can make the configuration on the LCD display. Power Output : 1000W Input AC/DC Voltage Range : 22v 60V or 45V 90V AC Output Voltage Range : 95-140VAC /185-265VAC Output Frequency : 46Hz65Hz Standby Power Consumption. Wind power grid tie inverter —- 1pcs, 2. Dump load resistor —1pcs, 3. AC cable –1pcs , 4. Limiter sensor/clamp / cable —- optional. Q: Can this inverter work if power off? Grid tie inverter will stop to work if the grid is off. Q :Can this inverter be connected in Parallel? A : Yes, the grid tie inverter is stackable. You may connect two or more inverters to one big wind turbine.
