- Control ambiental: Verifiqueu que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats.
5. Solució De Problemes
This section addresses common issues you might encounter with your solar charge controller.
| Problema | Causa possible | Solució |
|---|---|---|
| LCD Screen Blank | No power from battery or solar panels; internal fault. | Comproveu les connexions de la bateria i el voltage. Ensure solar panels are receiving sunlight. Try resetting the unit (refer to Section 3.3). If the issue persists, contact customer support. |
| Battery Not Charging / Low Amps | Insufficient solar input; incorrect battery type setting; faulty connections; controller malfunction. | Verify solar panel output. Confirm correct battery type setting (Section 2.3). Check all wiring for secure connections and correct polarity. Ensure panels are not shaded. |
| Controller Overheating / Melting | Overload; inadequate ventilation; internal short circuit; undersized controller for the system. | Reduce load. Ensure proper ventilation around the controller. Verify that the total current from solar panels and load does not exceed the controller's rated amperage (50A). If overheating persists, discontinue use and contact customer support. |
| Vol incorrectetage Lectura | Loose connections; calibration issue; faulty sensor. | Check all wiring connections. Compare readings with a multimeter. If discrepancies persist, a factory reset (Section 3.3) might help. |
