Deskripsi
Photovoltaic Controller (Power Series)
Model : SD600 200
Brand : Sungrow Power Supply
Features
·Common negative pole control mode, multi-channel solar cell array input control; ·Microcomputer chip intelligent control, charging and discharging parameter points can be set to meet the needs of different occasions; ·Each charging voltage detection has a “hysteresis” control function to prevent the switch from entering an oscillation state; ·The control circuit is completely isolated from the main circuit and has a very high anti-interference ability; ·Adopts LCD liquid crystal display screen, Chinese and English menu display; ·With historical record function and password protection function; ·With power AH accumulation function, including photovoltaic power generation, load power consumption, and battery power accumulation function; ·Complete protection functions, with a variety of protection and alarm functions; ·With RS485/232 communication interface, convenient for remote signaling and remote control; ·With a variety of fault alarm passive output contact functions; ·With clock display function; ·With temperature compensation function.
Optional functions :
·Dry contact function for starting control of oil engine or backup power supply; ·Time control and light control function: light-on and light-off mode, light-on and time-off mode, clock control and light-on and time-off at dawn can be selected at will; ·A dedicated lightning arrester can be provided according to the lightning protection level requirements of the system; ·Secondary power-off control function for main load and secondary load.
Charging mode:
It adopts a step-by-step current limiting charging mode, and automatically controls the connection or disconnection of the solar cell array in sequence according to the changing trend of the battery terminal voltage, so as to realize the safe and fast charging function of the battery pack.
Protection function:
It has protection and alarm functions such as reverse connection of solar cell array, anti-reverse charging at night, battery overcharging, battery over-discharging, overload, short circuit, etc.
