Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Input Level LED flashes quickly (red) Possible Cause: Input voltage is too high | Check the input voltage and reduce it. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
N/A | Input Level LED flashes slowly (red) Possible Cause: Input voltage is too low | The battery needs recharging. Check the cables and connections. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
N/A | Input Level LED flashes occasionally Possible Cause: Overheating | Switch off the inverter and the load. Wait about 5 to 10 minutes. The inverter is being reset. Then switch the inverter back on without the load. Reduce the load and make sure the inverter has better ventilation. Then switch the load back on. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
N/A | Load Status LED is constantly lit (red) Possible Cause: Short circuit or reversed polarity, or excessive load | Switch off the inverter and remove the load. Then switch the inverter back on without the load. If no excessive load is now shown, then there is a short circuit in the load or the total load was higher than the power specified on the data sheet. For MSI1812T, MSI1812TOE and MSI1824T: The fuse in the device must be pressed in again by hand after it is triggered. Check the cables and connections. If repairs are necessary, have repairs carried out by a specialist. | DIY Check / Tech Fallback |
