5. Setup
Follow these steps for proper installation:
- Location: Choose a dry, cool, and well-ventilated location for the inverter. Avoid direct sunlight, heat sources, and moisture.
- Power Off: Ensure the inverter's power switch is in the 'OFF' position before making any connections.
- Battery Connection: Connect the red positive (+) cable from the inverter's positive terminal to the positive (+) terminal of your 24V DC battery.
- Negative Connection: Connect the black negative (-) cable from the inverter's negative terminal to the negative (-) terminal of your 24V DC battery.
- Secure Connections: Double-check that all connections are tight and secure to prevent loose contacts, which can cause overheating or power loss.
- Polarity Check: Verify that polarity is correct. Reversing polarity will damage the inverter.
- Grounding: Connect the inverter's grounding terminal to a proper earth ground.

7. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter:
- Cleaning: Keep the inverter's exterior clean and free from dust and debris. Use a dry cloth for cleaning.
- Ventilation: Periodically check that the cooling fans and vents are clear and unobstructed.
- Connections: Inspect battery cables and terminals regularly for tightness and signs of corrosion. Clean any corrosion with a wire brush and baking soda solution.
- Storage: If storing the inverter for an extended period, ensure it is clean, dry, and stored in a cool place. Disconnect it from the battery.
8. Troubleshooting
Refer to this section for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | Inverter switch is OFF; Loose battery connections; Low battery voltage; Blown fuse. | Turn ON the inverter; Check and tighten battery cables; Recharge or replace battery; Check and replace fuse (if accessible and safe). |
| Overload alarm | Connected load exceeds 3500W. | Reduce the total power of connected devices. |
| Overheat alarm | Poor ventilation; Excessive ambient temperature; Overload. | Ensure clear airflow around the inverter; Move to a cooler environment; Reduce load. |
| Low/High voltage alarm | Battery voltage too low or too high. | Check battery voltage and charge/discharge as needed. Ensure battery is 24V. |
| Short circuit protection activated | Short circuit in connected device or wiring. | Disconnect all devices and check for faulty wiring or appliances. |
