5. Persediaan dan Pemasangan
5.1 Memasang Pengawal
Mount the solar charge controller vertically on a flat, non-flammable surface. Ensure there is adequate airflow around the unit for proper heat dissipation. Avoid mounting near flammable materials or in areas with excessive dust or moisture.
5.2 Sambungan Pendawaian
Follow the connection order carefully to prevent damage to the controller or other components. Always connect the battery first, then the solar panel, and finally the DC load.
- Sambungkan Bateri: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V atau 24V).
- Sambungkan Panel Suria: Connect the positive and negative terminals of the solar panel to the corresponding solar panel terminals on the controller. Ensure correct polarity.
- Sambungkan Beban DC: Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller. Ensure correct polarity.
Important: Disconnect components in the reverse order: Load, then Solar Panel, then Battery.
