6. ការដំឡើង (ដំឡើង)
Follow these steps for proper installation of your solar charge controller.
- ការដំឡើង៖ Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient space around the controller for heat dissipation. Use the mounting holes provided on the unit.
- ភ្ជាប់ថ្ម៖ Connect the battery to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -). The LCD display should illuminate, indicating the controller has detected the battery voltage.
- ភ្ជាប់បន្ទះថាមពលព្រះអាទិត្យ៖ Connect the solar panel to the solar panel terminals on the charge controller. Ensure correct polarity. The controller will begin charging the battery if sunlight is available.
