10. Troubleshooting

If you encounter issues with your ALLWEI 2000W Pure Sine Wave Inverter, refer to the following general troubleshooting steps. For specific error codes or persistent problems, consult the official ALLWEI support resources.

• No Power Output:
  • Check if the inverter is turned on (both main switch and remote).
  • Verify battery connections are secure and correct polarity.
  • Check battery voltage; if too low, recharge the battery.

• Inverter Shuts Down:
  • Overload: Reduce the connected load.
  • Low/High Voltage: Check battery voltage and charging system.
  • Overheating: Ensure adequate ventilation and clear any obstructions from cooling vents. Allow the inverter to cool down.
  • Short Circuit: Disconnect all loads and inspect for short circuits in wiring or appliances.
• Buzzer Alarm Sounds:
  • Refer to the LCD display for the specific warning indicator (e.g., low battery, overload, over-temperature).
  • Address the indicated issue. The alarm will typically cease once the condition is resolved.
• Noisy Operation:
  • Cooling fans will operate at higher speeds under heavy loads or high temperatures. This is normal.
