2. Safety Precautions
- 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.
- Connection: Always connect the inverter to a 12V DC battery. Ensure correct polarity (+ to + and - to -) to prevent damage. Use the provided battery connection cables.
- Grounding: Properly ground the inverter to prevent electrical shock.
- Load Capacity: Do not exceed the inverter's rated power output (2000W continuous, 4000W peak). Overloading can cause damage and fire hazards.
- Maintenance: Do not attempt to open or service the inverter yourself. Refer all servicing to qualified personnel.
- Battery Capacity: A minimum battery capacity of 12V 240AH is recommended for optimal performance. Insufficient battery capacity may lead to insufficient output voltage.

- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage / Inverter not turning on | Loose battery connections, low battery voltage, overloaded, internal fuse blown. | Check and tighten battery connections. Charge battery. Reduce load. Contact customer support if fuse is suspected. |
| Overload alarm / Inverter shuts down | Connected appliance exceeds inverter's rated power. | Disconnect overloaded appliance. Reduce total load. Restart inverter. |
| Over-temperature alarm / Inverter shuts down | Poor ventilation, high ambient temperature, excessive load. | Ensure clear airflow around inverter. Move to cooler location. Reduce load. Allow unit to cool. |
| Low battery alarm | Battery voltage is too low. | Charge the battery immediately. Disconnect load to prevent deep discharge. |
| Remote control display not working | Loose cable connection, faulty remote/cable. | Check and secure the remote control cable connection. If issue persists, contact customer support. |
