5. Налаштування та встановлення
Follow these steps for proper installation. Always ensure correct polarity and secure connections to prevent damage.
- Підключіть батарею: Loosen the screws on the battery terminals of the controller. Connect the positive (+) and negative (-) battery cables to the corresponding terminals. Ensure the connection is secure. The controller will automatically detect the system voltage (12 В/24 В).
- Підключіть навантаження: Loosen the screws on the load terminals. Connect the positive (+) and negative (-) load cables to the corresponding terminals.
- Підключіть сонячну панель: Loosen the screws on the solar panel (PV) terminals. Connect the positive (+) and negative (-) solar panel cables to the corresponding terminals.
- Підключення датчика температури (додатково): Insert the remote temperature sensor into the designated port on the controller. This allows for accurate battery temperature compensation during charging.
Важливо: Always connect the battery first, then the load, and finally the solar panel. When disconnecting, reverse this order: disconnect the solar panel, then the load, and finally the battery.
