INTRODUCTION

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.. Then inverter transfers the battery DC power into AC power for AC load use. As wind and sun are susceptible to different regions, seasons and weather. With the certain complementarity of the wind and solar resources, the controller can make full use of wind and solar energy and ensure the continuity and stability of power supply .

PERFORMANCE FEATURESPerfect protection function, thus the system has higher reliability.LCD display function, visually display battery voltage and charge current.Integrated design of controller and inverter, with simple structure and easy maintenance.Frequency toroidal transformer, ensures inverter has high efficiency and low no-load loss.Pure sine wave output, compared with square wave or modified wave, has higher efficiency and higher capability of driving load.PWM stepless unload mode, which burn the excess power into dump load, making the battery charging in best status.

OPTIONAL FUNCTIONSBy-pass function: It will switch to the city grid automatically when the battery is under-voltage or something wrong with the inverter, which ensures the continuity and stability of system.Chinese and English version : User can choose language versions according to requirement of Chinese and English or pure English Version.

APPLICATION AREASStand alone wind power station, photovoltaic power station and wind/solar hybrid power station.Stand alone domestic household wind/solar hybrid power system, wind power system .photovoltaic power system.GSM base stations, expressway and other no-residential regions.Coastal islands, remote mountainous, border posts for regions shortage of or without electricity.Government demonstration projects, landscape lighting project, street light project etc.

WARM PROMPTSCustomers, who will order the off-grid pure sine wave inverter, need to provide the following information:Rated battery voltageRated wind powerRated solar powerRated output capacity, rated output voltage, rated output frequency of the inverter.The load characteristic: Resistive load or Inductive load.With or without by-pass function: Customers should provide rated voltage and frequency of AC input if they need it.
