4. Setup

Careful installation is crucial for the performance and longevity of your hybrid inverter. Follow these general guidelines:

4.1 Site Selection:

• Install the inverter indoors in a clean, dry, and well-ventilated area.
• Ensure the ambient temperature is within the recommended operating range.
• Mount the inverter vertically on a non-flammable surface, allowing sufficient clearance for airflow around the unit.

4.2 Wiring Connections:

All wiring should be done with appropriate gauge cables and connectors, following local electrical codes.

1. Battery Connection: Connect the 24V battery bank to the inverter's battery terminals. Ensure correct polarity (positive to positive, negative to negative).
2. PV Array Connection: Connect the solar panel array to the PV input terminals. Verify that the PV open circuit voltage does not exceed 400V DC.
3. AC Input Connection: Connect the utility grid (if applicable) to the AC input terminals.
4. AC Output Connection: Connect your loads (appliances) to the AC output terminals.
5. Grounding: Ensure the inverter chassis is properly grounded.

5. Operating

Once installed, the inverter can be configured and operated via its LCD display and control buttons.

5.1 Initial Power-Up:

1. Ensure all connections are secure and correct.
2. Turn on the battery breaker.
3. Turn on the PV array breaker.
4. Turn on the AC input breaker (if connected to utility).
5. Press the power button on the inverter to turn it on.

5.2 LCD Display and Settings:

The LCD display provides real-time status and allows configuration of various operating parameters. Refer to the detailed instructions in the full product manual for specific menu navigation and parameter adjustments.

5.3 Charging Modes:

The inverter supports multiple charging priority modes to optimize energy usage:

• Solar Priority: Solar power is the primary source for charging batteries and powering loads. Utility power is used only when solar power is insufficient.
• Solar + Utility: Both solar and utility power are used simultaneously to charge batteries and power loads.
• Solar Only: Only solar power is used for charging. Utility power is not used for charging.

5.4 Output Modes:

The inverter can be configured to prioritize different power sources for output:

• Solar Priority, then Battery, then Utility: Loads are powered first by solar, then by battery, and finally by the utility grid if both solar and battery are insufficient.
• Solar Priority, then Utility, then Battery: Loads are powered first by solar, then by the utility grid, and finally by the battery if both solar and utility are unavailable.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your inverter.

• Cleaning: Periodically clean the inverter's exterior with a dry cloth. Ensure ventilation openings are free from dust and debris.
• Connection Checks: Annually inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion.
• Battery Health: Monitor battery voltage and health according to the battery manufacturer's recommendations.
• Environmental Check: Ensure the installation environment remains dry, well-ventilated, and within the specified temperature range.

7. Troubleshooting

If you encounter issues with your inverter, refer to the following common problems and solutions. For complex issues, contact technical support.

Common Issues:

• No Power Output: Check battery connections, PV input, AC input, and ensure the inverter is turned on. Verify that no protection features (e.g., undervoltage, overload) have been triggered.
• Battery Not Charging: Check PV array connections and voltage. Ensure solar panels are receiving adequate sunlight. Verify charging settings on the LCD display.
• Overload Warning: Reduce the connected load. The inverter will automatically attempt to restart after an overload condition.
• Overtemperature Warning: Ensure adequate ventilation around the inverter. Clear any obstructions from cooling vents. Allow the unit to cool down.
• Fault Codes: Refer to the full product manual for a list of specific fault codes displayed on the LCD and their corresponding troubleshooting steps.
