- 플랫 마운트: Use the included bracket to mount the controller on a surface.
Ensure adequate space around the controller for air circulation to prevent overheating.
3.2 배선 연결
Follow the correct wiring sequence to prevent damage to the controller or battery:
- 배터리를 연결하십시오: First, connect the battery to the controller's battery terminals (7). Ensure correct polarity (positive to positive, negative to negative). The LCD will power on.
- 태양광 패널 연결: Next, connect the solar panel to the controller's solar terminals (8). Ensure correct polarity.
- DC 부하 연결: Finally, connect your DC loads to the controller's load terminals (6). Ensure correct polarity.
연결 해제 순서: To disconnect the system, reverse the order: disconnect the load, then the solar panel, and finally the battery.
This wiring diagram illustrates the proper connection order for the solar panel, battery, and DC load to the HQST solar charge controller.
When connecting wires, ensure they are inserted into the correct square socket for the cable, not the screw hole. Fully unscrew the terminal screws, insert the wire ends, then tighten the screws securely.
3.3 배터리 유형 설정
The controller automatically recognizes 12V/24V Sealed (AGM), Gel, and Flooded batteries. For Lithium batteries, manual parameter setting is required:
The LCD display allows for manual adjustment of battery parameters, especially crucial for Lithium-ion batteries.
- Press and hold the 'Up & Down' button to enter the setting mode.
- Use the 'Up & Down' buttons to navigate to the battery type setting (e.g., "b01" for Gel, "b02" for Sealed, "b03" for Flooded, "b04" for Lithium).
- For Lithium batteries, further adjust charging voltag예, 과방전 용량tage, and other parameters as per your battery manufacturer's specifications.
- Press and hold the 'Load' button to save the settings and exit.
4. 사용 설명서
4.1 LCD 디스플레이 탐색
The LCD screen provides real-time monitoring of your solar system:
The intuitive LCD screen cycles through various operational data, including battery voltag전자, PV 권tage, charge current, load current, controller temperature, and battery state of charge (SOC).
- Press the 'Up & Down' button (2) to manually cycle through the displayed parameters.
- The display will automatically cycle through parameters if no button is pressed for a few seconds.
4.2 부하 제어
The controller features a DC load output with multiple control modes:
- Press the 'Load' button (4) to manually turn the DC load output on or off.
- The controller supports 17 different load control modes, allowing for customized operation (e.g., dusk-to-dawn, timed operation). Refer to the full manual for detailed instructions on setting load modes.
4.3 USB 충전 포트
The integrated 5V 1A USB port (1) can charge small electronic devices. This port is active when the DC load output is enabled.
4.4 4-에스tage 스마트 충전
The controller employs an advanced 4-stag배터리 상태 및 수명 최적화를 위한 충전 알고리즘:
