MWS Series

Applications   

  • Independent wind power plant
  • Independent household wind power generation system
  • Power supply for those unmanned regions like mobile communication station, high way, the coastal islands, remote mountainous regions and border posts.
  •  Regional research projects, government demonstration projects, landscape lighting projects for those places with insufficient power or power shortages.

Features

  • Can be applied to wind&solar hybrid off-grid system
  • Several functions are optional, such as wind speed measure function, rotational speed control function and temperature compensation function.
  • RS232/RS485/RJ45/GPRS/Bluetooth/Zigbee optional. ( It can be monitored by app for those with GPRS/WIFI/Bluetooth connection)
