4. Why choose AH-10KW Wind turbine?
Using the world's leading mechanical centrifugal variable pitch technology, the average annual power generation is 30% more.
★Excellent
Large initial blade angle (+9°), excellent acceleration performance, start at low wind speed of 2.5m/s;
★Efficiently
Below the rated wind speed, the wind turbine outputs efficiently;
★Stable
Above the rated wind speed, adjust the pitch angle so that the rotor speed is maintained near the rated speed and the power output is stable.
The use of variable pitch technology has greatly improved the efficiency of wind turbine power generation,The graph of increased power is shown below:

● For off-grid system –Marching MPPT Charge controller
● For on-grid system –Marching MPPT Wind controller/ Growatt inverter
● For Hybrid system –Marching hybrid inverter
● Wind turbine MPPT track point adjustable by yourself.
●Off-grid system wind turbine low cut in wind speed charge.
●Complete protection function.
●Several functions are optional, such as PV control function, wind speed measure function, rotational speed control function and temperature compensation function.
● RS232/RS485/RJ45/GPRS/WIFI/Bluetooth/Zigbee optional. ( It can be monitored by app for those with GPRS/WIFI/Bluetooth/RJ45 connection).
