 Reliability:

Intelligentized, modularized design, simple mechanism, powerful functions. With industrial range superior components and strict production technology, the controller can be used in relatively bad working environment and has reliable performance and long life-span.

 PWM Stepless Dumpload Mode:

When the power generated by wind turbine and solar panel exceed battery capacity, the controller will release residual power. Common control mode is to dumpload all the power. However, the battery is not full actually. That all the power was consumed via resistors makes resource tremendously wasteful. Even with staging dumpload, it can be just divided into five to six stages, the effect is still unsatisfied. Our company adopts PWM (Pulse Width Modulation) stepless dumpload mode. In another word, the controller can dump residual power with division into thousands of stages. It can dump residual power while charging battery banks, which is benefit to effectively extend battery longevity.

 Voltage Limiting and Current Limiting Charge Mode:

When battery voltage exceeds the pre-set dumpload voltage point, the controller will adopt PWM voltage limiting charge mode. It dumps the excess energy in order to extend the battery longevity. When wind turbine charging current exceeds pre-set brake current point, the controller will automatically start brake to protect battery. (e.g.: WWS06-48-N: If battery voltage exceeds charge shutoff voltage or wind turbine current exceeds wind turbine brake current, the controller will automatically start brake.)

 Two DC Outputs Mode:

Each DC output has various control modes for choice, including: Constant on; Constant off; Constant half-power; light-control on, light-control off; light-control on, time-control off; light-control on, time-control half-power, light-control off; light-control on, time-control half -power, time-control off. Users can set three output control modes by LCD buttons: constant on; light-control on, light-control off; light-control on, time-control off.

 LCD Display Function:

LCD screen can display system status and parameters via intuitionistic digital and graphic form. Such as: battery voltage, wind turbine voltage, PV voltage, wind turbine current, PV current, wind turbine power, PV power, load current, output control modes, time control output shutoff hours, light control on/off voltage points, day or night indication, load status, battery over voltage/under voltage status etc.

 Perfect Protection Functions:

Battery over charge protection, battery over discharge protection, battery anti-reverse connection protection; load short circuit, over load protection; wind turbine current limiting, automatical brake, manual brake protection; solar anti-reverse charge, solar anti-reverse connection; lightning protection etc.

(Note: Following optional functions are valid only for controllers which have these functions)

 Optional Remote Communication Function:

The software can monitor real-time system running status, which contain all the parameters on the LCD screen. Through the software, users can not only set and adjust relevant parameters, but also can control the wind turbine and load running status, and alarm while malfunction happens.

 Optional Low Voltage Charge Function:

Boost module is added in the controller to help wind turbine charge battery banks even in low wind or the wind turbine rotates in low speed. User can adjust the admittance value and start charge voltage via software according to different wind turbine parameters.

 Optional By-pass Function:

When the battery is under voltage, the controller will automatically switch to the utility grid to get power for driving load to ensure the continuity of the system.

 Optional Temperature Compensation Function:

The controller can adjust the dumpload voltage according to different ambient temperature so that the battery charge is in the best efficiency.

 Optional SD card Function:

With SD card, controller store system history data when the controller disconnected with PC.

 Optional Wind Speed Detection Function:

The controller can detect real-time wind speed when it is matched with appointed anemometer. User can read the real-time wind speed via monitoring software.

 Optional Micro-current Charge Function:

When the wind turbine input voltage reaches to the pre-set value, the controller will produce the micro-current charge for the battery.

 Optional Wind Turbine Rotate Speed Detection Function:

User can read the real-time wind turbine rotate status via monitoring software.

User should connect and operate all parts according to following procedures after wind turbine, solar panel and external circuit constructions are finished.

Step 1 Check the package and then check the controller for damage after unpacking. Damaged controller is not allowed to be installed in the system.

Step 2 Connect DC load to “DC OUTPUT” terminals: The first load should be connected to "+" and "-1" of the “DC OUTPUT” terminals, the second load should be connected to "+" and "-2" of the “DC OUTPUT” terminals.

Step 3 Connect battery to “BATTERY” terminals with 6mm2 copper cables or above.

Note: The controller has anti-reverse connection protection function, but wrong polarity of battery shall be forbidden!

Step 4 Connect wind turbine output line to “WIND INPUT” terminals when the wind turbine is under static status or in low speed running status. If the wind turbine is single-phase DC output, just connect the positive pole line to(+) “WIND INPUT” terminal, negative pole line to (-)“WIND INPUT” terminal.

Step 5 Connect solar panel positive wire to (+) “SOLAR INPUT” terminal, negative wire to (-) “SOLAR INPUT” terminal.

Step 6 If the controller has the remote communication function, user can read and set relevant parameters via software.

Step 7 User can set relevant parameters and load output control modes through LCD buttons.

Step 8 Check whether all the connections are correct and firm.
