3. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully:
- ກະກຽມສາຍໄຟ: Ensure all wires are of appropriate gauge for the current and length, and that all connections are clean and secure.
- ເຊື່ອມຕໍ່ແບັດເຕີຣີ: Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V ຫຼື 24V).
- ເຊື່ອມຕໍ່ແຜງແສງອາທິດ: Connect the solar panel array to the charge controller. Again, observe correct polarity. The controller will begin charging the battery.
- ເຊື່ອມຕໍ່ການໂຫຼດ: Finally, connect the DC load to the charge controller's load terminals. Do not exceed the maximum rated load current.
Important: Always connect the battery first and disconnect the battery last to prevent damage to the controller.
