Bluelight technology&wellsee solar wind generators series products have a spike in sales in October, In order to promote the development of photovoltaic industry and meet the needs of our fresh and old customers,wuhan wellsee new energy industry company as a professional manufacture of solar controller has lauchs 2 models of three stage charge and discharge solar controller with high speed USB data transfer function WS-SC2440U/WS-SC2470U.These two new products can be applied in all kinds of solar panel and lead-acid battery (charge curves of other batteries can be customized),MCU(Microprocessor control unit) is with PWM(Pulse Width Modulation) procedure. They can provide high speed optimal charge voltage¤t from the PV panel according to the type of battery and power supply condition
WS-SC2440U/ WS-SC2470U is researched according to latest technical standard communication protocol and voltage technical standard. It continues the success of three stage charge and discharge controller, the new function is with LCD screen display for monitoring charge discharge voltage,current and power counting in real time. Meanwhile the product is with USB port used for charging mobile phone or tablet pcs,three-phase power consumption can be adjusted. Newly U-series products adopt pwm technology, makes it to be a kind of low loss series connection controller.
New generation three stage charge and discharge solar controller WS-SC2440U/WS-SC2470U is with features as follows:
•clearly showed Multifunction LCD display, show the run data of connected equipment and working condition in the mode of number and words.
•USB port for charging the mobile phone or tablet pc.
•Auto recognition and show the type, model number and related data information of connected equipment.
•navigation function button, convenient operation, direct observation, speedy
•can finish the real time monitoring of connected controller,remote charging,load switch, the data scan and modification of equipment parameter,charging control parameter,load control parameter
•real time display and voice alarm for fault information of connected equipment
•low voltage cut and battery voltage when restore the connection dc output load terminals can be set
•Intelligent temperature compensation
Wellsee new energy new product three stage charge and discharge solar controller WS-SC2440U is with the current degree:20A,30A,40A,WS-SC2470 is with the current degree:50A,60A,70A .automatic recognition input voltage 12v/24v/48v,it is mainly applied in solar photovoltaic system to coordinate the work of solar panel,battery and load. Besides with the overload protection, battery overcharge protection,short circuit protection,reverse discharging protection, reverse polarity protection, thunder protection, low voltage protection functions of regular solar controller, Wellsee solar three stage charge and discharge 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”.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.
It is worth mentioning:ws-sc2440u ws-sc2470u can be used for all kinds of solar panel and battery,
with industrial standard MCU and pwm variable duty cycle function. Dynamically adjust PWM parameters according to the battery type and charging real condition, can get high speed best charging voltage and current from the PV panel, increases charging efficiency and avoid overcharging, effectively protect the life of the battery. 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 ect functions. Making the whole solar power system with high security and efficiency operation.
Wellsee new energy produces international high standard Chinese independent brand wellsee solar controller, hitting overseas markets. Changing the passive situation of china solar charge discharge controller in foreign market is a great goal to wellsee.As the constant breakthrough of photovoltaic industry technology in our country, the research and application of wellsee solar charge controller will be more and more perfect along with the improvement of theoretical study and production technology, play a important role in national economy and people’s daily life.
