4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of the inverter. Consult a qualified electrician for installation if you are unsure.
4.1 Site Selection
- Install the inverter in a cool, dry, and well-ventilated area.
- Avoid direct sunlight, high temperatures, and humidity.
- Ensure sufficient clearance around the inverter for airflow.
- Mount the inverter vertically on a non-flammable surface.
4.2 Wiring Connections
Follow these steps for wiring. Always ensure all power sources are disconnected before making connections.
- Battery Connection: Connect the battery bank (24V) to the inverter's battery terminals. Ensure correct polarity (+ to + and - to -).
- PV Array Connection: Connect the solar panels to the PV input terminals. Observe the correct voltage and current limits (30-400V DC).
- AC Input Connection: Connect the AC utility grid (if used) to the AC input terminals.
- AC Output Connection: Connect your AC loads to the AC output terminals.
- Grounding: Ensure the inverter is properly grounded according to local electrical codes.

5. Operating Instructions
The inverter features an intuitive LCD display and control buttons for easy operation.
5.1 LCD Display and Control Panel
Figure 4: Close-up of the inverter's LCD display showing real-time power visualization and control buttons (ESC, DOWN, UP, ENTER).
The LCD displays real-time data such as input voltage, output voltage, battery status, and charging/discharging information. Use the ESC, DOWN, UP, and ENTER buttons to navigate menus and adjust settings.
5.2 Charging Modes
The inverter supports four distinct charging modes:
- PV Priority: Solar energy is prioritized for charging batteries and powering loads. Utility grid is used as a backup.
- Utility Priority: Utility grid is prioritized for charging and loads. Solar energy is used when the grid is unavailable.
- Hybrid Charging: Combines solar and utility power for charging and loads, optimizing energy use.
- Only Solar Charging: Batteries are charged exclusively by solar power.
5.3 Load Output Working Modes
The inverter offers three load output modes:
- PV Priority: Loads are powered primarily by solar energy.
- Utility Priority: Loads are powered primarily by the utility grid.
- Inverter Mode: Loads are powered by the inverter from battery storage.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Keep the inverter clean and free from dust. Use a dry cloth to wipe the exterior.
- Ventilation: Ensure ventilation openings are not blocked. Periodically check for dust accumulation in fan areas.
- Connections: Periodically check all electrical connections for tightness and signs of corrosion.
- Battery Health: Monitor battery voltage and health, especially for lead-acid batteries.
- Firmware: Check the manufacturer's website for any available firmware updates.
The inverter's fans operate based on load or temperature. If loads are less than 500W, fans activate when the internal temperature reaches 45°C. For loads exceeding 500W, fans start immediately.
7. Troubleshooting
The LCD display will show error codes to assist in troubleshooting. Refer to the following general guidance:
- No Power Output: Check battery connections, AC input, and ensure the inverter is turned on. Verify battery voltage is within operating range.
- Overload Warning: Reduce the connected load. The inverter may shut down to protect itself from damage.
- Over-temperature Warning: Ensure adequate ventilation. Clean any dust blocking air vents. Allow the unit to cool down.
- Battery Low Voltage: Charge the batteries. Check solar panel connections and output, or AC input if using grid charging.
- Error Code Displayed: Note the specific error code and consult the full product manual or manufacturer's support for detailed resolution steps.
