5.1 Mounting

• Mount the inverter vertically on a sturdy surface.
• Ensure adequate clearance around the unit for proper heat dissipation.

5.2 Wiring Connections

1. Battery Connection: Connect the battery bank to the inverter's battery terminals (POS+ and NEG-). Ensure correct polarity.
2. PV Input Connection: Connect the solar panel array to the PV input terminals (PV+ and PV-). Verify correct polarity and voltage within the specified range.
3. AC Input Connection: Connect the utility grid or generator AC supply to the AC input terminals (L, N, Ground).
4. AC Output Connection: Connect your loads (home appliances) to the AC output terminals (L, N, Ground).
5. Grounding: Ensure the inverter is properly grounded.

Warning: Incorrect wiring can cause damage to the inverter, batteries, and connected loads, and poses a risk of electric shock. Always consult the detailed wiring diagrams in the full product manual and adhere to safety guidelines.

6. Operation

6.1 Power On/Off

1. Ensure all wiring connections are secure.
2. Turn on the battery breaker first.
3. Turn on the PV array breaker (if applicable).
4. Press the Power On/Off switch (6) on the inverter.
5. The LCD display (1) will illuminate, and the status indicator (2) will show the operational status.

6.2 LCD Display and Function Buttons

The LCD display provides real-time operational data and allows for configuration of various settings. Use the function buttons (5) to navigate menus and adjust parameters.

6.3 Working Modes and LED Indicators

Image 5: This image illustrates the LED light patterns (RGB) indicating different working modes of the inverter. The logo light changes color to signify the current operational state: Stationary mode, PV Mode (Purple Light), Utility Mode (Blue Light), and Battery Mode (Red Light).

The inverter's logo light provides a quick visual indication of its current working mode:

• Stationary Mode: Default or standby state.
• PV Mode (Purple Light): Inverter is primarily drawing power from the PV array.
• Utility Mode (Blue Light): Inverter is primarily drawing power from the utility grid.
• Battery Mode (Red Light): Inverter is primarily drawing power from the battery bank.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter.

• Cleaning: Keep the inverter's exterior clean and free from dust. Ensure ventilation openings are not obstructed.
• Connections: Periodically check all electrical connections for tightness and signs of corrosion.
• Environment: Ensure the operating environment remains within specified temperature and humidity ranges.
• Battery Health: Monitor battery voltage and health according to battery manufacturer guidelines.

Caution: Disconnect all power sources (PV, AC, Battery) before performing any maintenance or cleaning.

8. Troubleshooting

This section provides guidance for common issues. For complex problems, contact technical support.

• No Power Output: Check AC input, battery connections, and ensure the inverter is powered on. Verify circuit breakers are not tripped.
• No Charging: Check PV input voltage and current. Ensure solar panels are clean and receiving adequate sunlight. Verify battery connections.
• Fault Indicator On: Refer to the inverter's LCD display for specific error codes. Common faults include overload, over temperature, or short circuit. Address the cause and restart the inverter.
• Inverter Shutting Down: This could be due to overload, low battery voltage, or over temperature. Reduce load, check battery charge, or ensure proper ventilation.
