3) In the 48V system, separate reverse connect battery or separate reverse connection of solar panel controller will not damage; but if in reverse connection of the battery and is connected solar panels, or solar panels on the reverse connection is connected to the battery may cause damage to the controller. 4)The battery contains a large amount of energy. Therefore, in no cases should the battery be short circuited. It's recommended that a fuse be serially connected to the battery.
2). When "load mode" is displayed, long press to enter into the load mode setting. Press to adjust the mode, and long press for 2s to save and exit; or else, the system will not save the setting that was just made and automatically exit the setting interface after 12s. 10.
Short-circuit automatic recovery time: 1st time, 5 s; 2nd time, 10 s; 3rd time, 15 s; 4th time, 20 s; 5th time, 4 hours or automatic recovery the next day; or long press to make the load resume output. 13. Communication Port Line Sequence (Only for Controllers with Communication Functions) Controller communication port RJ12 (6-pin) 14. Installation Instructions and Precautions 1. The controller shall be installed securely, and its dimensions are as follows: 2. Installation hole diameter: 3.
3. Precautions: ①If it is 12V system, the bottom left corner of LCD display will show '12V', 24V system will show' 24V', ② The first step is to connect the battery. If the connection is made correctly, the controller screen will light up; otherwise, check whether the connection is correct. ③ The second step is to connect the solar panel.
16. Common Problems and Solutions Symptoms Causes and Solutions LCD screen does not light up Check whether the battery is correctly connected. Incomplete display or no renewal on LCD screen Check whether the ambient temperature is too low and whether the display recovers when the temperature rises. Check whether the solar panel is correctly connected and contact No charging with sunlight present is good and reliable. Check whether the solar panel voltage falls below the battery voltage.
