- Connect to Battery:
- Connect the other end of the red positive (+) cable to the positive (+) terminal of the 12V battery.
- Connect the other end of the black negative (-) cable to the negative (-) terminal of the 12V battery.
- Double-check all connections for polarity and tightness. Loose connections can cause overheating and damage.
- Initial Power On: Once all connections are secure, press the power button on the inverter. The LCD display should illuminate, indicating the inverter is operational.
5. Operating Instructions
This section details how to use your Technaxx Inverter TE23.
5.1 Powering On/Off
- To turn on the inverter, press and hold the power button (Ⓞ) for a few seconds until the LCD screen illuminates.
- To turn off the inverter, press and hold the power button (Ⓞ) again until the LCD screen turns off.
5.2 Connecting Devices
The inverter provides 230V AC power through its Schuko sockets and 5V DC power through its USB ports.
- Ensure the inverter is powered on.
- For AC devices, plug the device's power cord into one of the 230V Schuko sockets. Ensure the device's power consumption does not exceed the inverter's continuous rating (3000W).
- For USB devices, connect your USB-A or USB-C charging cable to the respective port on the inverter. The USB-A port supports Quick Charge 3.0.
- Monitor the LCD display for real-time information on input voltage, output voltage, frequency, and load.

5.3 Understanding the LCD Display
The LCD display provides critical operational information:
- DC Voltage: Shows the current input voltage from the 12V battery.
- AC Voltage: Displays the output AC voltage (typically 220V or 230V).
- Frequency: Indicates the output AC frequency (typically 50Hz).
- Load Indicator: Shows the approximate load percentage on the inverter.
- Power/Normal/Fault Indicators: LEDs indicating operational status or error conditions.

6. Protection Features
The Technaxx Inverter TE23 incorporates several safety features to protect itself and your connected devices:
- Low Voltage Shut-off: The inverter will automatically shut down and sound an alarm if the input DC voltage drops to approximately 10.2V to protect the battery from deep discharge.
- Over Voltage Protection: Shuts down if the input voltage exceeds a safe limit.
- Overload Protection: Shuts down if the connected load exceeds the inverter's maximum continuous or peak power rating.
- Over Temperature Protection: The integrated cooling fan activates to dissipate heat. If the temperature continues to rise to unsafe levels, the inverter will shut down.
- Short Circuit Protection: Protects against damage from short circuits on the output.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter.
- Cleaning: Periodically clean the exterior of the inverter with a soft, dry cloth. Ensure the cooling vents are free from dust and debris. Do not use liquid cleaners.
- Connections: Regularly check all electrical connections (battery terminals, output sockets) to ensure they are tight and free from corrosion.
- Ventilation: Ensure the area around the inverter remains clear to allow for proper airflow and cooling.
- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
