Wellsee grew to a record, successfully applying to a number of patents.
 
   New generation of Wellsee LCD remote control unit WS-MT58 is a supporting set which designed by the latest communications protocol and the voltage technical standards of controller. Through LCD display and the function keys operation, it can real-time monitor the data and working status of each online single controller. Such as battery voltage, charge current, discharge current, charge AH, discharge AH, and environmental temperature ; read the control parameters of charge and discharge current and set the parameters of overcharge voltage, over-discharge voltage, recovery voltage; fast load the default operating parameters; rapidly start and stop charging, discharging unit and so on.
 
New generation wellsee LCD remote control unit WS-MT58 is with features as follows:
 
• Automatically recognize and display connected devices type, model and related parameters
 
•Display clear large multifunctional LCD screen, display operating data and working status of devices connected in digital and text form.
 
•Four navigation function buttons, easy to operate, fast and convenient
•Monitor real-time data, view and modify remote charging, load switching, device      parameters, the charge control parameters, load control parameter data.
 
•Display real-time data of connected devices and voice alarm
•Based on RS485 communication bus, communication distance is longer
 
WS-SC2410 wellsee intelligent solar controller (wellsee solar three stage charge and discharge controller, wellsee photovoltaic controller), applies in solar photovoltaic systems, which coordinates the working of solar panels, batteries and loads. WS-SC2410 wellsee intelligent solar controller apply to all types of photoelectric panels and various types of batteries, Using industrial-grade MCU (Micro Control Unit) has PWM (Pulse Width Modulation) variable duty cycle function. It can dynamically adjusting PWM parameters, and supply the best and fast charging voltage and current, increase charging efficiency according to the types of battery and charging status, it also can prevent overcharging and protect the battery life effectively. In addition, added with overall protection ,overload protection(with automatic recovery), overcharge, short circuit protection, thunder protection, reverse discharging protection, reverse polarity protection(with automatic recovery), low voltage protection etc. functions, making the whole solar power system with high security and efficiency operation.
 
WS-SC2410 wellsee intelligent solar controller is totally different from other controllers with three stage charging mode: it charges by battery charging characteristic curve and adapts to intelligent three stages 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(factory defaults, 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 adjust PWM and keep the charge current keep in floating status until battery voltage is up to 14.2V, charging is over.
 
 
If the starting 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 starting 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.
 
Wuhan wellsee new energy is specialized in research, production and sales of solar energy & wind energy related products. For now we have solar controller, solar inverter, automotive inverter, solar panel, wind turbine etc. up to 85kinds of high-tech products and export to more than 112 countries. wellsee will adhere to independent research and development, continuous innovation!
