9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on. | Battery is completely discharged. | Connect to AC power and charge for at least 30 minutes. |
| AC output not working. | AC output not activated; device power exceeds 1000W. | Press the AC power button; reduce the load or use a lower-power device. |
| Charging is slow or not occurring. | Incorrect adapter; solar panel not in direct sunlight; dual charging not optimized. | Ensure correct adapter (18-24V); reposition solar panel; verify both AC and solar inputs are connected for dual charging. |
| Display flickering or unclear. | Temperature difference between internal and external components. | This can occur due to fanless design. Allow unit to stabilize in ambient temperature. If persistent, contact support. |
