4. 설정
Follow these steps for proper installation of your HQST MPPT Solar Charge Controller:
- 설치: Choose a dry, well-ventilated location away from direct sunlight and heat sources. Ensure adequate space around the controller for air circulation. The controller dimensions are approximately 5.91" x 2.42" x 4.16" (L x W x H).
- 배터리 연결: Connect the battery cables to the battery terminals on the charge controller. Ensure correct polarity (positive to positive, negative to negative). This connection must be made first.
- 태양 전지 패널 연결: Connect the solar panel cables to the solar panel terminals on the charge controller. Ensure correct polarity.
- 부하 연결(선택 사항): If using a DC load directly from the controller, connect the load cables to the load terminals. Ensure correct polarity.
- 온도 센서(선택 사항): Connect the external temperature sensor to the designated interface. This allows for temperature compensation of battery charging voltage.
- Remote Meter (Optional): Connect the remote meter (RM-6) to the communication interface for external display and control.
