2. Safety Information
WARNING: Failure to follow these safety instructions may result in injury, damage to the inverter, or damage to connected devices.
- Ventilation: Ensure adequate ventilation around the inverter. Do not block cooling vents.
- Environment: Install the inverter in a dry, cool, and well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Avoid exposure to moisture or water.
- Grounding: The inverter chassis must be properly grounded to prevent electrical shock.
- Battery Connection: Connect the inverter directly to a 12V DC battery. Ensure correct polarity (red to positive, black to negative). Incorrect connection will damage the inverter.
- Load Capacity: Do not exceed the inverter's continuous power rating of 4000W. Overloading can cause damage and fire hazards.
- Children: Keep the inverter out of reach of children.
- Maintenance: Do not attempt to open or service the inverter yourself. Refer all servicing to qualified personnel.

5.3. Storage
If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output power / Inverter not turning on | Loose battery connections, low battery voltage, blown fuse, inverter switch off | Check battery connections, charge battery, check/replace fuses, ensure inverter switch is ON. |
| Overload alarm / Inverter shuts down | Connected load exceeds 4000W continuous power or 8000W peak power | Reduce the total wattage of connected devices. Disconnect some appliances. |
| Overheating alarm / Inverter shuts down | Poor ventilation, blocked cooling fan, high ambient temperature | Ensure adequate airflow around the inverter. Clear any obstructions from the cooling fans. Move to a cooler environment. |
| Low voltage alarm / Inverter shuts down | Battery voltage too low | Recharge or replace the battery. |
| High voltage alarm / Inverter shuts down | Battery voltage too high | Check battery charging system. Ensure battery voltage is within the specified range (10V-15V DC). |
