Product Characteristic:
1,This product is manufactured according Chinese standard GB/T19064-2003 or according the customer’s request.
2,Adopt PWM multistep sequential limiting current charge method, auto control multiple solar array connection or shut off orderly according to the battery group voltage change tendency.
3,Adopt multiple-circuit charging-control circuit and individual killer switch on each circuit.
4,With auto protection function of over charge, electronic short circuit, anti-reverse protection. Prevent the battery group reverse charging to the solar panel array at night.
5,Big intuitionistic LCD screen shows the working status of solar panels, battery and controller. ( the voltage, current, power of solar energy panel and battery)
6,Power switch driving circuit is completely isolated from sampling circuit. The control signals is transmitted by opto isolation, with super-high disturbence rejection and stability.
7,Power switch driving circuit is completely isolated from sampling circuit. The control signals is transmitted by opto isolation, with super-high disturbence rejection and stability.
8,There are lightning protection device inside the controller. Limit instantaneous overvoltage which entered into solar panels under a level which the system can withstand; or unload the strong lightning current to the ground. To protect the equipment from lightning surge.
9,Adopts the industrial-grade chips for all control, which can work under the cold, hot, humid conditions.
10,Temperature compensation function. Compensate the temperature according different battery type.
11,Fixable communication solution with RS-232,RS-485,USB,GPRS,Etherner,etc.
