4. Setup and Installation
Follow these steps for safe and correct installation of your inverter:
- Placement: Choose a dry, well-ventilated area away from direct sunlight, heat sources, and moisture. Ensure sufficient clearance around the unit for airflow.
- Battery Connection: Connect the 12V inverter battery to the inverter terminals. Ensure correct polarity: red cable to positive (+) terminal and black cable to negative (-) terminal. Secure connections tightly.
- Mains Input: Plug the inverter's input power cord into a properly grounded wall outlet.
- Load Connection: Connect your appliances to the output sockets of the inverter. Do not overload the inverter beyond its rated capacity (756 Watts).
- Initial Power On: Once all connections are secure, switch on the inverter using the power button. Observe the indicator lights for normal operation.

5. Operating Instructions
The Eco Watt Neo 1050 operates automatically to provide uninterrupted power.
Indicator Lights:
- MAINS: Illuminates when grid power is available and the inverter is charging the battery.
- CHARGING: Indicates that the battery is currently being charged.
- ECO: Indicates the inverter is operating in ECO mode, which prioritizes energy efficiency.
- UPS: Illuminates when the inverter is providing power from the battery (during a power cut).
- LOW BATT: Flashes or illuminates when the battery charge is low, indicating it needs recharging.
- OVERLOAD: Illuminates when the connected load exceeds the inverter's capacity.
Normal Operation:
- When grid power is present, the inverter charges the battery and passes mains power to the connected appliances. The MAINS and CHARGING indicators will be active.
- Upon a power failure, the inverter automatically switches to battery power, and the UPS indicator will illuminate. This transition is typically very fast to prevent appliance disruption.
- When grid power resumes, the inverter switches back to mains power, and resumes charging the battery.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter and battery.
- Cleaning: Keep the inverter unit clean and free from dust. Use a dry cloth to wipe the exterior. Do not use liquid cleaners.
- Ventilation: Ensure that the ventilation openings are not blocked to prevent overheating.
- Battery Check: Periodically check the battery terminals for corrosion. Clean them if necessary and ensure connections are tight. For flooded batteries, check electrolyte levels regularly and top up with distilled water as needed.
- Load Management: Avoid consistently overloading the inverter. Distribute loads evenly or reduce non-essential appliances during power cuts.
7. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on | Loose battery connections, discharged battery, no mains input. | Check battery terminals, ensure battery is charged, verify mains power supply. |
| OVERLOAD indicator active | Too many appliances connected. | Reduce the number of connected appliances. |
| LOW BATT indicator active | Battery is low on charge. | Allow the battery to charge when mains power is available. Reduce load if on battery power. |
| No power output during power cut | Battery not connected, battery fully discharged, inverter fault. | Check battery connections, ensure battery is charged. If problem persists, contact customer support. |
| Inverter making unusual noise | Internal component issue, fan obstruction. | Ensure ventilation is clear. If noise persists, contact customer support. |
