6. Setup
6.1 Battery Recommendations
Selecting the appropriate battery capacity is crucial for optimal performance and runtime. Refer to the table below for recommended battery capacities based on device wattage and desired running time.

6.2 Connection Diagram
Follow these steps to connect your inverter:
- Prepare the Battery: Ensure your battery is fully charged and in a well-ventilated area.
- Connect Battery Cables: Connect the red battery cable to the positive (+) terminal of the inverter and the positive (+) terminal of your battery. Connect the black battery cable to the negative (-) terminal of the inverter and the negative (-) terminal of your battery. Ensure connections are tight.
- Connect Ground Wire: Connect a ground wire from the inverter's ground wire port to a suitable ground point.
- Connect Remote Control: Plug the RJ45 cable from the remote control into the RJ45 remote port on the inverter.
- Connect Solar Panels (Optional): If using with a solar system, connect your solar panels to a charge controller, and then the charge controller to your battery.
- Initial Power On: With no AC loads connected, turn on the inverter using the main power switch or the remote control. Check the LCD display for correct input/output readings.
- Connect AC Appliances: Once the inverter is operating correctly, plug your AC appliances into the inverter's output sockets.

9. Troubleshooting
The inverter is equipped with multiple protection functions and a buzzer reminder system to alert you to potential issues:

- Input Low Voltage Shutdown Protection: Inverter shuts down if DC input voltage drops too low (e.g., 10V±0.3V for 12V system). Buzzer: 2 beeps.
- Input High Voltage Shutdown Protection: Inverter shuts down if DC input voltage rises too high (e.g., 15.5V±0.3V for 12V system). Buzzer: 3 beeps.
- Battery High and Low Voltage Alarm: Buzzer sounds to warn of critical battery voltage levels.
- Overload Protection: Inverter shuts down if connected load exceeds its capacity. Buzzer: 5 beeps.
- Output Short Circuit Protection: Protects against short circuits in the AC output.
- Overheating Protection: Inverter shuts down if internal temperature exceeds 75°C. Buzzer: 4 beeps.
Automatic Reset Function: After an input high voltage or low voltage shutdown, the inverter will automatically restore output voltage once the input voltage returns to normal operating range.
Buzzer Reminder: If any protection is triggered, the buzzer will sound an alarm to alert the user.
Common Questions:
- Rated Power vs. Surge Power: The inverter has a continuous rated power of 3000W, meaning it can supply 3000W of power continuously. The surge power of 6000W is a temporary peak power output, typically for a very short duration (0.1 seconds), used to start appliances with high initial power demands.
10. User Tips
- Remote Control Cable: The remote control uses a standard RJ45 cable. If you need to increase the remote control distance, you can replace the included 4-meter cable with a longer standard RJ45 network cable.
- Appliance Compatibility: Always verify that your appliances are compatible with a modified sine wave inverter before connecting them. Sensitive electronics or appliances with motors may require a pure sine wave inverter.
- Battery Sizing: Use the provided battery recommendation table (Figure 6.1) to select a battery with adequate capacity for your intended use to ensure sufficient runtime.
