Follow these steps carefully to install your solar charge controller. Incorrect installation can damage the device or other components.

1. Mura Aaye fifi sori ẹrọ: Choose a dry, well-ventilated indoor location away from direct sunlight, high temperatures, and moisture. Ensure there is enough space around the controller for heat dissipation.
2. So batiri pọ: Connect the battery to the charge controller first. Ensure the battery has sufficient voltage (at least 10V for 12V systems, 20V for 24V systems) for the controller to recognize the battery type. Connect the positive (+) and negative (-) terminals correctly. The battery cable should be as short as possible to minimize voltage ju.
3. Solar Panel: Connect the solar panel to the charge controller. Ensure correct polarity (+ to + and - to -). The controller is designed for solar modules only; do not connect other power sources.
4. Connect the DC Load (Optional): If you have a DC load, connect it to the load terminals of the controller. Ensure correct polarity.
5. Jẹrisi Awọn isopọ: Double-check all connections for correct polarity and secure fastening.

Akiyesi pataki: Disconnect components in the reverse order: first the load, then the solar panel, and finally the battery.
