Deskripsi
Photovoltaic Controller
Model : SD1220
Brand : Sungrow Power Supply
Features :
· LCD display function: The LCD screen displays important information of the system to the user in numbers and English; such as battery voltage, charging current and discharging current working mode, system parameters, system status, etc.;
· Automatic/manual/night function: The control mode of the load can be programmed to be automatic or manual. In manual mode, the load can be manually turned on or off. At this time, the night function is invalid. When the night function is selected, the controller turns off the load during the day; when it detects that it is night, it automatically turns on the load after a delay, and automatically turns off the load when the timing time is up. The delay time and timing time can be programmed;
· It has a temperature compensation function for floating charge voltage.
Charging Mode :
· Fast charging function: When the battery voltage is lower than a certain value, the fast charging function starts automatically, and the controller will increase the battery charging voltage. When the battery voltage reaches the ideal value, the fast charging countdown program starts, and the timing time is up, and the fast charging state is exited. Therefore, it can make full use of solar energy. · Working mode: normal charging and discharging mode, light-on and light-off mode, light-on and light-off mode.
Protection function :
Battery overcharge, over discharge, output overload, over voltage, over temperature, battery reverse connection, PV reverse connection and other protection functions.
