wind energy turbine
Features of Hummer H9.0-20000w:
quiet noise,nice structure,low start-up wind speed and high output efficiency.
It introduces several patented technologies and special materials.
All the off-grid wind turbines are matched with wind-solar hybrid inverter controller, which can connect solar panel simultaneously.And grid-tied system can be connected to the local grid with Hummer grid-tied inverters.
