Why choose GVH-5KW wind turbine?
Advantage:
1.Torque Patent Technology: use newest “Precise Coil” technology.
2.No hysteresis and gear notches effect make the start torque very low <1N.M ,it can make the wind turbine have low start wind speed.
3.Original Structure: use disc coreless motor to take place traditional motor makes it less drag
4.Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.
Why choose GVH-5KW wind turbine?
·Power Curve Tracking Function
● For off-grid system –Marching MPPT Charge controller
● For on-grid system –Marching MPPT Wind Invertor
● 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)
