6. Problemų sprendimas
This section addresses common issues you might encounter with your Tracer 3215BN controller.
6.1 Controller Not Powering On
- Patikrinkite akumuliatoriaus jungtį: The controller requires a minimum battery voltage to power on. Ensure the battery is properly connected and has sufficient charge. If the battery is completely discharged, the controller may not power on until an external 12V source or sufficient solar input is provided to raise the battery voltage.
- Patikrinkite poliškumą: Confirm that the battery connections are made with correct polarity.
- Inspect Fuses/Breakers: Check any inline fuses or circuit breakers between the battery and the controller.
6.2 No Charging Indication
