4. Setup
4.1. DC Connections
Connect the inverter to your 12V DC battery bank using high-quality copper cables. Ensure proper polarity: connect the red terminal on the inverter to the positive (+) terminal of the battery and the black terminal on the inverter to the negative (-) terminal of the battery. Secure all connections tightly to prevent arcing and ensure efficient power transfer.

5. Operating Instructions
To operate the AIMS Power Inverter:
- Ensure all DC and AC connections are secure and correctly wired.
- Press the Power button on the front panel to turn on the inverter. The green Power LED indicator should illuminate.
- Plug your AC devices into the outlets or ensure your hardwired system is connected.
- Monitor the LED indicators for any fault conditions (red Protect LED).
- If using the optional remote panel, you can power the inverter on/off from a remote location.
6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your inverter:
- Cleanliness: Keep the inverter clean and free from dust and debris, especially around the cooling fans and vents. Use a dry cloth for cleaning.
- Connection Checks: Periodically inspect all DC and AC connections for tightness and signs of corrosion. Loose connections can cause overheating and reduce efficiency.
- Ventilation: Ensure that the area around the inverter remains unobstructed to allow for proper airflow and cooling.
- Battery Health: Maintain your battery bank according to the battery manufacturer's recommendations. A healthy battery bank is crucial for inverter performance.
7. Troubleshooting
The AIMS Power Inverter is designed with several protection features. If the inverter shuts down or the red Protect LED illuminates, refer to the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not powering on | Loose DC connections, low battery voltage, blown fuse. | Check and tighten DC connections. Recharge or replace battery. Check internal fuses (professional service recommended). |
| Red Protect LED on (Overload) | Connected load exceeds inverter's continuous or surge rating. | Reduce the connected load. Disconnect devices and restart the inverter. |
| Red Protect LED on (Over-temperature) | Inadequate ventilation, blocked fans, high ambient temperature. | Ensure clear airflow around the inverter. Clean fans and vents. Allow unit to cool down. |
| Red Protect LED on (Low Voltage) | Battery voltage dropped below 9.5V. | Recharge the battery bank. Check battery health. |
| Red Protect LED on (High Voltage) | Battery voltage exceeded 16V. | Check charging system (e.g., solar charge controller, alternator) for overcharging. |
| Red Protect LED on (Short Circuit) | Short circuit in AC wiring or connected appliance. | Disconnect all AC loads. Check AC wiring for shorts. |
If troubleshooting steps do not resolve the issue, please contact AIMS Power technical support.
