EEWS 2000W
ENGELEC
EEWS Series 2000W Wind/solar Hybrid Controller
Applications
Ø Independent wind power plant
Ø Independent household wind power generation system
Ø Power supply for those unmanned regions like mobile communication station, high way, the coastal islands, remote mountainous regions and border posts.
Ø Regional research projects, government demonstration projects, landscape lighting projects for those places with insufficient power or power shortages.
Features
Ø Can be applied to wind&solar hybrid off-grid system
Ø Several functions are optional, such as wind speed measure function, rotational speed control function and temperature compensation function.
Ø RS232/RS485/RJ45/GPRS/Bluetooth/Zigbee optional. ( It can be monitored by app for those with GPRS/WIFI/Bluetooth connection)
