Hummer provides off-grid style wind turbines from 500w to 20kw ,They are highly advanced in technology and reliable in practice . Hummer off-grid style wind turbine equipped with hummer wind-solar hybrid inverter ,it is a battery-charging style designed from independent power system .The wind-solar hybrid inverter is a ALL-IN-ONE system ,which adopts the functions of controlling ,battery charging and inverting .It is compatible for direct link with Solar Panel without any other equipment . Through the technology of SPWM, Its output is stable pure sine AC .In side ,it adopts CPU smart control ,control circuit is simplified ,made reliable and sensitive to outside environment change .By using most advanced module ,the energy loss drops to the minimum extent .Its CPU center will continuously check the battery status to protect it from over charging ,over discharging .And hummer ALL-IN-ONE inverter also designed with protection against over load ,over current and over heat ,It is strong and compatible output for loads . In addition, Hummer wind turbine ALL-IN-ONE inverter also offers convenient status monitoring ,users can either check various working data on the LCD screen in front panel of the wind generator inverter ,or view through computer which can be linked to the inverter through RS485 port by side . At last , different from other inverter that is so big like wardrobe , Hummer ALL-IN-ONE inverter is small as a PC computer case .
