  remote solar controller








   WS-SC2430M  Wellsee  remote solar controller   (also called wellsee three-stage solar controller/ wellsee photovoltaic controller ) applies in solar photovoltaic system which coordinates the working of solar panels, batteries and loads. This controller is different from other solar controllers which can monitor the running data and modify the parameters of controller by connecting with MT58 LCD displayer unit or PC monitoring software and other communications devices. It increases the comprehensive protective functions so that the entire system can operate efficiently and safely. 


WS-SC2430M Wellsee remote controller applies to all types of solar panel and batteries. Adopting industrial grade MCU (Micro processing controller) has PWM (Pulse Width Modulation) program with variable duty cycle functions. It can provide fast and best charging voltage and current from the PV panel and dynamically adjust the pwm parameters  According to different types of batteries and charging state. So thatimproved charging efficiency, while preventing overcharging and the effective protection of battery life.


Wellsee remote controller is totally different from other controllers with three stage charging mode: it charges by battery charging characteristic curve and adopts intelligent three steps charging mode “constant current- constant voltage and limited current-Purling floating”. It make the battery full of power

Three-stage charging mode (take 12V 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 13.7V(can be set)

2. Constant voltage charge stage: controlled by PWM, the battery voltage is kept at 13.7V, 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 14.2V, 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.
