Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Input voltage is too high (Quick flash LED) Possible Cause: Input voltage exceeds normal operating limits (> 30.0 V) | Check the input voltage and reduce it. | DIY Safe |
N/A | Input voltage too low (Slow flash LED) Possible Cause: Battery voltage dropped below 21.0 V | The battery needs recharging. Check the cables and connections. | DIY Safe |
N/A | Overheating (Occasional flash LED) Possible Cause: Thermal overload inside the inverter or on the cooling element | Switch off the inverter and the consumer. Wait 5 to 10 minutes and switch the inverter on again without any electric consumers. Reduce the load and make sure the inverter has better ventilation. Then switch the consumer back on. | DIY Safe |
N/A | Short circuit or reversed polarity / Excessive load (Constantly lit LED) Possible Cause: Short circuit in the consumer, reversed polarity, or total load exceeded data sheet specifications | Switch off the inverter and remove the consumer. Then switch the inverter back on without the consumer. If no excessive load is now shown, check the consumer for a short circuit or check total load and cables/connections. | DIY Safe |
