4. Setup and Installation
Before installation, ensure the inverter is placed on a stable, flat surface in a well-ventilated area, away from direct sunlight, heat, and moisture. Ensure sufficient clearance around the unit for airflow.
4.1 Battery Connection
- Ensure the inverter's power switch is in the "OFF" position.
- Connect the red battery cable to the positive (+) terminal of the 24V battery bank and the positive (+) DC input terminal on the inverter.
- Connect the black battery cable to the negative (-) terminal of the 24V battery bank and the negative (-) DC input terminal on the inverter.
- Ensure all connections are tight and secure to prevent loose connections and sparking.

4.2 Grounding Connection
Connect the provided grounding wire from the inverter's ground terminal to a reliable earth ground point. This is essential for safety and to prevent electrical hazards.
4.3 AC Input (Mains Power) Connection for Charging and UPS Function
If you intend to use the inverter's charging and UPS (Uninterruptible Power Supply) functions, connect the AC input cable from a standard 220V AC mains power outlet to the AC input port on the inverter.

Figure 4.2: Diagram showing the automatic power conversion process. When mains power is available, it prioritizes mains power and charges the battery. If mains power fails, it seamlessly switches to battery power within 20 milliseconds.
5. Operating Instructions
5.1 Powering On/Off
- To Power On: After all connections are secure, switch the ON/OFF button on the inverter's front panel to the "ON" position. The LCD display will illuminate, and the inverter will begin operation.
- To Power Off: Switch the ON/OFF button to the "OFF" position. The LCD display will turn off, and the inverter will cease operation.
5.2 Understanding the LCD Display
The intelligent LCD display provides real-time information about the inverter's status:
- Input Voltage (DC): Displays the current voltage of your 24V battery bank.
- Output Voltage (AC): Shows the current AC output voltage (220-240V).
- Input Frequency: Displays the frequency of the incoming AC power (if connected).
- Output Frequency: Displays the output AC frequency (50 Hz).
- Charging Status: Indicates if the battery is charging and the charging current.
- Running Time: Shows the accumulated operating time.
- Error Messages: Displays specific error codes or messages if a fault occurs.
