Wellsee three -stage solar controller is totally different from other controllers with three stage charging mode:it charges by battery charging characteristic curve and adopts to intelligent three steps charging mode "constant current- constant voltage and limited current-Purling floating",It make the battery full of power and it has advanced human-machine interactive function that user can adjust charging voltage.

 

Three-stage charging mode (take 48V system as an example.)

1.Constant current fully charge stage: directly charging battery by using constant current output characteristic until the voltage of battery is up to 54.8V (can be set)

2. Constant voltage charge stage: controlled by PWM, the battery voltage is kept at 54.8V, till charge current is less than Purling current floating charge voltage;

3. Purling current floating charge stage: continue to control by PWM and keep the charge current keep in floating status until battery voltage is up to 56.8V, charging is over.

 

If the started voltage of battery is higher than the lowest protection voltage, the system will go to the Purling current floating charge stage automatically to prevent frequent overcharging; if started charge voltage is lower than the lowest protection voltage, the system will go to three-stage charge mode.

 

Three-stage charge mode uses constant current charging at the beginning and the end, and uses constant voltage charging in the intermediate stage. When the current is decayed to the set value, it switches from the second stage to the third stage. This mode can make the outlet minimum to protect the battery better and really charge the battery fully.

 

WS—SC4860 Wellsee three-Stage charge controller applies to all types of solar panel and lead-acid batteries(other types of batteries can be set charging curve according to customer's requirement), MCU (Micro processing controller) has PWM (Pulse Width Modulation) program. It can provide fast and best charging voltage and current from the PV panel according to different types of batteries and power supply of panels .

 

Functions:  

Intelligent three stage charging mode: constant current charge→ constant voltage and limited current charge→ purling current floating charge .

1.CPU control, LCD display
