Suzhou Yueniao Machinery & Electronics Imp & Exp Co Ltd is one of the pioneer renewable energy business and has been in this field since 2002. We are dedicated exclusively to the business of small wind generator, mini hydroelectric generator and solar energy. As a manufacturer with advanced technology, we are making in our own workshop the wind turbine from 300w to 20kw with CE certificates. Beside that we are dealing with business of mini hydroelectric generator from 200W up to 60KW and solar panel from 20W to 280W. We do not claim any of its products to be the best, but we are proud to hear the owners of our products praise them. And that is what makes all the time and effort we spend on our products worthwhile. Thank you for your support!

Wind & Solar Hybrid Charge Controller



Controller is for battery charging only. It can only directly connect to battery. You should never connect controller directly to any other devices such as inverters. Connecting controller to inverters or other devices than battery may pose risk of fire hazard and have wind turbine/electrical failure.


The WWS03A multifunctional Hybrid Solar/Wind controller combines the functions of AC to DC rectifier and load control for wind and/or solar systems. It eliminates the need for separate rectifier, solar charge controller and wind turbine controller. It is the most cost effective solution for renewable energy systems.

The WWS03A hybrid charge controllers is suitable for wind turbine with permanent magnet generator or hydro system with permanent magnet generators, which has a 3-phase AC output within the corresponding voltage range. It rectifies and regulates the generator’s 3 phase alternating current in order to be able to charge battery banks in a smooth and safe way. The WWS03A hybrid charge controllers also protects the batteries from over-charging through its dump load techniques.

When the battery has reached fully charge state, the excess current from the generator is transferred to a dump load via solid state MOSFETs


  1. _ High Reliability: Efficient ventilation design ensure reliable and efficient operation. _ Great for hybrid wind/solar system, hybrid controller can support battery charging from simultaneous wind generator load and solar load combined up to 750 w. _ Load control and diversion control: The controller has over-charge protection, short-circuit protection, poleconfusion protection and automatic dump-load function. It is reliable with a highly efficient, long service life.

Warning :

Before proceeding to the installation, make sure that the wind generator’s shaft is NOT spinning(the 3 phase generator is NOT generating electricity)

  • Connect the wind generator 3-phase AC wires to controller’s “WIND INPUT” terminals (no sequence).
  • Connect solar panel to “SOLAR INPUT” terminals on the controller. Skip this step if solar panel is not used. Make sure the positive & negative terminals of solar panel are connected to positive & negative solar terminals on the controller. (Please check polarity is correct).  Solar panel must be rated 12V for 12V controller, solar panel must be rated 24V for 24V controller. Higher voltage solar panel will damage the controller or cause controller malfunction.

3. Connect battery to "BATTERY” terminals; make sure the positive & negative poles of battery are connected to positive & negative battery terminals. (Please check
polarity is correct). Properly sized circuit breaker must be installed between controller and battery to prevent wind turbine freewheeling and battery short-circuit.


Output voltage of some solar panels is much higher than 12V or 24V, and this may trigger the dump load early.  Please make sure the maximum output voltage of solar panels is below 14Vfor 12V controllers and below 28V for 24V controllers.
