| Problem | Cause | Corrective action |
| 1. No output voltage and no lighting of warning lights (LED off) | High output voltage | Check the battery voltage and switch off the charger |
| DC fuse burnt out | Replace the fuse | |
| Switch set on remote control, but this is not available | Place the switch to ON | |
| 2. No voltage in output, LED of battery charge is ON | Batteries flat | Charge the batteries, the inverter will switch on when the battery voltage exceeds 24 V |
| 3. No voltage in output, temperature LED in ON | The inverter is overloaded | Reduce the charge and let the inverter cool down |
| 4. No output voltage, LED “ON” is lit | Inverter is in stand-by | Connect a charge or modify the jumper’s settings |
| 5. Low voltage in output | Low power supply = jumper adjustment | Connect a charge > 30 W or modify the jumper’s settings |
| 6. The inverter turns on and off, the “ON” LED and the battery charger LED flash in turns | Batteries flat | Disconnect the charge and charge the batteries |
| Wires are too thin | Replace with wires of correct diameter | |
| The connections are corroded or faulty | Tighten connections. If wires are burnt out, replace them | |
| 7. The inverter lights ON/OFF, the ON LED is lit, the “overload” LED flashes once a second and the fan operates at full speed. | The inverter is overloaded | Reduce the inverter load |
| The inverter has been switched off ten times as a result of an overload or short- circuit condition | Reduce the load or the short-circuit. Reset the inverter manually through ON/OFF switch |
