EEWS Series 3000W Wind/solar Hybrid Controller

EEWS Series 3000W Wind/solar Hybrid Controller for Independent wind power plant, and Independent household wind power generation system. Can be applied to wind&solar hybrid off-grid system

EEWS Series 3000W Wind/solar Hybrid Controller


connection


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)
