Product Details

off grid 12kw power supply PV controller

Product Description

PERFORMANCE FEATURES:

n 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.

n Adopt multiple-circuit charging-control circuit and individual killer switch on each circuit.

n 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.

n Big intuitionistic LCD screen shows the working status of solar panels, battery and controller. (the voltage, current, power of solar energy panel and battery)

n 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.

n 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.

n Adopts the industrial-grade chips for all control, which can work under the cold, hot, humid conditions.

n Temperature compensation function. Compensate the temperature according different battery type.

n Fixable communication solution with RS-232, RS-485,USB,GPRS,Etherner,etc.
