Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | All LEDs flash 5 times in succession and a buzzer sounds (repeats after a short pause). Possible Cause: The PCB is overheated. | Let the charger cool down. Restart the battery charger as soon as the house battery is no longer fully charged. | DIY Safe |
N/A | The LED of the alternator and solar panel are lit continuously. Possible Cause: Ambient temperature is below -2°C with flooded or LiFePO4 charging curve selected. | This is a normal protective mechanism. As soon as the ambient temperature rises above 0°C, the LEDs switch off. | DIY Safe |
N/A | The alternator LED flashes 6 times. Possible Cause: Voltage drop detected at alternator, insufficient alternator power, cable power failure, or electronic malfunction. | Ensure cables have a minimum cross-section of 10 mm² (or 16 mm² if length > 2 m). Ensure connections on sockets 1, 2, 3, and 6 are secure and correctly connected. | DIY Safe |
N/A | The charge was interrupted, starting battery overcharged, solar panel overvoltage, or alternator overloaded. Possible Cause: Incorrect battery type, incorrect charging curve, starting battery overheated/swollen, solar overvoltage, or high voltage drop on positive/negative side. | Ensure suitable battery type and charging curve are selected. Check that starting battery and ambient temperature are within limits. Verify voltage drop on positive and negative circuits is less than 0.2 V under load. Check alternator voltage regulator and fuses. | DIY Safe |
N/A | The battery charger reduces output current and switches itself off after some time. Possible Cause: The battery charger and/or power source is overheated. | Let the battery charger cool down. It switches back on automatically when its temperature drops. | DIY Safe |
