• Securely mounted to prevent movement or damage.

4.2 DC Battery Connection

1. Ensure the inverter's power switch is in the OFF position.
2. Connect the RED battery cable to the positive (+) terminal of your 12V DC battery.
3. Connect the other end of the RED cable to the positive (+) DC input terminal on the inverter.
4. Connect the BLACK battery cable to the negative (-) terminal of your 12V DC battery.
5. Connect the other end of the BLACK cable to the negative (-) DC input terminal on the inverter.
6. Tighten all connections securely using the provided thimble spanner to prevent loose connections and arcing.

The inverter is compatible with various 12V battery types, including Lithium (LI), Flooded (FLD), Gel, Sealed Lead-Acid (SLD), and Absorbed Glass Mat (AGM) batteries.

4.3 Grounding the Inverter

For safety, the inverter must be properly grounded. Connect a grounding wire (not included) from the inverter's grounding terminal to a suitable earth ground point (e.g., vehicle chassis, ground rod).

4.4 AC Output Connection

• Plug your AC-powered devices directly into the dual AC sockets or the 20A outlet on the front panel of the inverter.
• For higher power loads or permanent installations, utilize the hardwire port. Consult a qualified electrician for hardwire connections.

4.5 Remote Controller Connection

Plug the remote controller cable into the designated remote controller port on the inverter's front panel. The remote allows for convenient power control and monitoring from a distance.

5. Operation

5.1 Powering On/Off

After all connections are secure, turn on the inverter using the ON/OFF switch located on the inverter unit or the remote controller. The LCD display will illuminate, indicating the inverter is operational.

5.2 Understanding the LCD Display

The intelligent LCD display provides real-time information about the inverter's status:

• DC Input Voltage: Shows the current voltage from your 12V battery.
• AC Output Voltage: Displays the inverter's output voltage (110V/120V).
• Battery Level: Indicates the approximate charge level of your battery.
• Load Level: Shows the percentage of the inverter's capacity being used by connected AC devices.
• Working Status/Error Codes: Displays 'WORKING' during normal operation or a specific error code if a fault occurs.

5.3 USB and AC Outlet Usage

• The 5V 2.1A USB port can be used to charge compatible USB devices.
• The dual AC sockets and 20A outlet provide standard AC power for your appliances. Ensure the total wattage of connected devices does not exceed the inverter's continuous power rating.

5.4 Output Voltage and Frequency Adjustment

The output voltage and frequency can be adjusted within a small range using specific tools. Refer to the detailed instructions in the full product manual for the precise procedure, as incorrect adjustments can affect connected devices.

6. Troubleshooting

The inverter's intelligent LCD display provides error codes to help diagnose issues. Refer to the table below for common error codes and their solutions:

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter.

• Cleaning: Keep the inverter's exterior clean and free from dust. Use a dry cloth. Do not use liquid cleaners.
• Ventilation: Periodically check that the ventilation openings are clear and not obstructed by dust or debris.
• Connections: Regularly inspect all DC and AC connections to ensure they remain tight and secure. Loose connections can cause overheating and damage.
• Fuses: The inverter is equipped with internal fuses for protection. If a fuse blows, it indicates a significant fault. While spare fuses are provided, fuse replacement should only be performed by a qualified technician.
