ZWS 2KW wind/pv hybrid controller

The wind/solar hybrid controller is control device which can control wind turbine and solar panel at the same time and transform wind and solar energy into electricity then store to the battery bank. Wind/solar hybrid controller is the most important part in off-grid system, whose performance has much effect on life expectancy and operation of the whole system, especially the battery expectancy. Life span of battery will be shortened by over charge or over discharge in any case.

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)
