Setup
Connecting the Inverter
Follow these steps to properly connect your EDECOA Power Inverter:
- Ensure the inverter's power switch is in the "OFF" position.
- Connect the red battery cable to the positive (+) terminal of the inverter and the positive (+) terminal of your 12V battery. Ensure a secure connection.
- Connect the black battery cable to the negative (-) terminal of the inverter and the negative (-) terminal of your 12V battery. Ensure a secure connection.
- If using the ET-RC remote controller, plug its RJ45 cable into the "ET-RC Remote" port on the inverter.
- Place the inverter in a well-ventilated area, away from direct sunlight, heat sources, and moisture. Ensure proper air circulation around the cooling fans.

Operating Instructions
Using the Remote Controller (ET-RC)
The ET-RC remote controller provides convenient monitoring and control of your inverter:
- After connecting the ET-RC cable to the inverter, the LCD display on the remote will activate.
- The display shows real-time information such as DC input voltage, AC output voltage, frequency, battery capacity, load level, temperature, and fan status.
- Use the power button on the remote to turn the inverter ON or OFF remotely.
- The dual USB ports (5V 2.1A) on the remote can be used to charge compatible USB devices.
- Observe any protection indications on the LCD, such as overload or low voltage warnings.

Safety Precautions
To ensure safe operation and prevent damage to the inverter or connected devices, please adhere to the following safety guidelines:
- Do not connect the inverter to AC distribution wiring.
- Ensure proper ventilation around the inverter to prevent overheating.
- Keep the inverter away from water, moisture, and flammable materials.
- Do not open the inverter casing. There are no user-serviceable parts inside.
- Always connect the inverter to a 12V DC power source. Connecting to a higher voltage will damage the unit.
- Ensure the total power consumption of connected devices does not exceed the inverter's continuous power rating.
- Disconnect the inverter from the power source when not in use or during maintenance.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your inverter:
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Ventilation: Ensure the cooling vents and fans are free from dust and debris. Blocked vents can lead to overheating.
- Connections: Regularly check all cable connections to ensure they are tight and secure. Loose connections can cause power loss or overheating.
- Storage: When storing the inverter for extended periods, ensure it is disconnected from the battery and stored in a cool, dry place.

Troubleshooting
If you encounter issues with your EDECOA Power Inverter, refer to the table below for common problems and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | Inverter switch OFF; Loose battery connections; Low battery voltage; Overload protection activated. | Turn switch ON; Check and tighten connections; Recharge battery; Reduce load. |
| Overload alarm/shutdown | Connected load exceeds inverter capacity. | Reduce the total wattage of connected devices. |
| Over-temperature alarm/shutdown | Poor ventilation; High ambient temperature; Blocked cooling fans. | Ensure adequate ventilation; Move inverter to cooler area; Clear fan obstructions. |
| Low battery voltage alarm/shutdown | Battery voltage is too low. | Recharge or replace the 12V battery. |
| Fan not running | Inverter is not under sufficient load or temperature to activate fan. | This is normal operation; fan activates when needed for cooling. |
