Descripción del producto

MPPT LED solar charge controller 30a  with factory price  
Product introduction:

1,A product overview
Solar MPPT controller is designed specially for the solar system's; equipment can not only efficiently to solar panel electricity to charge the storage battery, but also provides a powerful control function.
Features: the controller is characterized in that the working voltage intelligent control solar maximum power point of solar panels, to always work in the V-A characteristic curve. Compared with the ordinary solar controller, use of electricity from solar panels power rate increased *0-30%! The controller uses solar intelligent charging. On the solar panel battery electric energy more than storage, control system automatically switches off the charging, thereby ensuring the best battery charging characteristics, making the battery fully utilized.
 Because the battery can only afford the charging current and the floating charge voltage must, over current and over voltage charging will cause serious damage to the battery. The controller through the real-time detection of battery charging voltage singlechip and charging current, charging voltage and charging current through the control of PV to limit the battery and charging current, make sure that the battery can be filled, and can not be damaged, thereby ensuring the service life of the battery.
Digital good intelligent controller, the core device uses MCU powerful control, so the periphery circuit structure is simple, and the control mode and control strategy for flexible and powerful; the power device is using imported components quality, so as to ensure the performance and stability of the controller is excellent.
In addition, the controller has the protection function, perfect include: lightning protection, solar reverse charging, battery reverse polarity and open circuit protection etc..
2.Performance characteristics and protection function:
uIntelligent design, simple structure, strong control function, stable performance, safe and reliable products.
uWith MPPT charging, the charging efficiency than ordinary PWM method has more superiority
uThe selection of large size LED display, when the user visible all parameters
uButton operation function of humanity, all the parameters can be self adjusted according to user requirements, easy for use in a variety of environments
uWith multi output functions, constant power / half power / sub period such as custom properties
uLiquid crystal display and battery voltage and charging current
uMains complementary function uninterrupted soft handoff, ensure the load duration work (this function to order)
uA digital and intelligent control
uNight protection function
1), the battery reverse connection protection storage battery is connected reversely, equivalent to short-circuit, will produce great instantaneous current. The controller then accidentally reverse connection in the circuit, the fuse will automatically fuse, which makes the whole battery disconnection the loop, effectively protect the battery and the equipment
2), the battery open circuit protection after long-term use, the battery open circuit or poor contact may occur. The controller will protect the equipment itself, not to be damaged in the battery open circuit after
3), Overload protection controller will automatically cut off the circuit in overload conditions
Dual mode of 6 kinds of output
1), light open, light off;
2), light open, time close;
3), normally open;
4), the half power light open, light off;
5), the half power light open, time close;
6), the half power normally open;

RS232/RS485 real time communication (timing)

Through serial communication, the realization of computer monitoring of the whole system, and the management of data analysis.

Serial port support upgrade program

You can upgrade program through the serial port, modify some customization function

On the wrong machine, the lower position machine two-way set (custom)

Support PC (computer) and the next machine (controller) two-way set parameters

LED multistage menu display

The controller adopts LED display, support multi-level menu view, display rich content, humanized design

3.environmental requirements
1), the working environment temperature range of -35 DEG C to 55 C
2), storage temperature range of -35 DEG C to 80 C
3), 10%, 90% no condensation humidity range
4), the level of protection IP30
It is prohibited to use in flammable and explosive gas environment, beware of the flame and spark!
4.security and protection
The controller has the advantages of preventing multiple reverse, solar battery reverse connection, battery open circuit, lightning protection and overvoltage protection function.
Note: lightning protection refers to the equipment necessary for the final level of protection, lightning prone areas, require multipole lightning protection system uses special lightning protection device etc.. If the user has this requirement, the need to increase the corresponding distribution system level cost, that when ordering.
5. After sale service
Service commitment: the machine free of charge for one year warranty, life-long maintenance. More than the warranty period or transportation, improper use of that damage, damage or natural disasters such as the irresistible, are not covered under the warranty. If the contract has special instructions to the contents of the contract shall prevail. And the statement: the company reserves the product change power, product updates anger not notice

6. Company Information
Anhui Sunli Electric Co.,Ltd,is a wholly-owned hold king company of Anhui Sanli group, specialized in producing and selling new energy products, such as solar controller, solar pv, solar power system, solar street light, solar heating system etc. It adheres to the service of cooperative development and common progress, implements the management philosophy of self-promotion, kind heatedness, establish warm productions atmosphere of appreciate life, and work hard with conscientiousness, creating products filled with harmonious to the customers and provides superior pre-sales consolation and after-sales service.
