5.2 LCD Display and Monitoring
The LCD display provides real-time information about the inverter's status:
- Input Voltage (V): Displays the DC voltage from the battery.
- Output Voltage (V): Displays the AC output voltage.
- Output Power (W): Shows the current power consumption of connected AC devices.
- Error Messages: Indicates specific issues (e.g., overload, low voltage, overheating).
The inverter is designed for low no-load power consumption, typically less than 9W, to conserve battery life when no devices are actively drawing significant power.

7. Troubleshooting
If you encounter issues with your Erayak inverter, refer to the LCD display for error messages and consult the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output / Inverter not turning on | Loose battery connections, low battery voltage, blown fuse, inverter switch off. | Check battery cable connections. Recharge or replace battery. Check internal fuses (professional service recommended). Ensure inverter switch is ON. |
| Overload alarm / Inverter shuts down | Connected appliance wattage exceeds inverter's continuous or peak rating. | Reduce the load by disconnecting some appliances. Ensure total wattage is within the inverter's limits. |
| Overheating alarm / Inverter shuts down | Poor ventilation, blocked fan vents, high ambient temperature. | Ensure adequate ventilation around the inverter. Clear any obstructions from fan vents. Allow inverter to cool down. |
| Low voltage alarm / Inverter shuts down | Battery voltage is too low. | Recharge the battery. Disconnect the inverter from the battery if not in use to prevent deep discharge. |
| Short circuit alarm | Short circuit in connected AC appliance or wiring. | Disconnect all AC appliances and check for faulty wiring or devices. |
| Inaccurate power meter readings | Known characteristic for very low loads (under 100W) or minor voltage discrepancies. | This is generally not a functional fault. For precise measurements, use an external, calibrated multimeter. |
