~Product Characteristics
◆This product is manufactured according Chinese standard GB/T19064-2003 or according the customer’s request.
◆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.
◆Adopt multiple-circuit charging-control circuit and individual killer switch on each circuit.
◆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.
◆Big intuitionistic LCD screen shows the working status of solar panels, battery and controller. ( the voltage, current, power of solar energy panel and battery)
◆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.
◆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.
◆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.
◆Adopts the industrial-grade chips for all control, which can work under the cold, hot, humid conditions.
◆Temperature compensation function. Compensate the temperature according different battery type.
◆Fixable communication solution with RS-232,RS-485,USB,GPRS,Etherner,etc.
