5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of the inverter. It is highly recommended that installation be performed by a certified electrician or solar professional.
- Site Selection: Choose a location that is dry, well-ventilated, and protected from direct sunlight, rain, and excessive dust. Ensure the ambient temperature is within the specified operating range.
- Mounting: Securely mount the inverter to a sturdy vertical surface using the provided mounting hardware. Ensure there is sufficient clearance (at least 20 cm) around all sides for proper airflow.
- Wiring Connections:
- Battery Connection: Connect the battery bank to the inverter's DC input terminals, observing correct polarity (+ to + and - to -). Ensure battery voltage matches the inverter's 24V requirement.
- AC Input Connection: Connect the AC mains or generator power source to the inverter's AC input terminals.
- AC Output Connection: Connect your loads (appliances, distribution board) to the inverter's AC output terminals.
- PV Input Connection: Connect the solar panel array to the inverter's PV input terminals, ensuring the PV voltage does not exceed 500V. Observe correct polarity.
- Grounding: Connect the inverter's ground terminal to a reliable earth ground.
- Initial Power-Up: After all connections are secure and verified, switch on the battery breaker first, then the AC input breaker (if applicable), and finally the PV input breaker. The inverter will initiate its startup sequence.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Periodically clean the inverter's exterior with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
- Connection Check: Annually, or as needed, inspect all electrical connections (AC, DC, PV, ground) for tightness and corrosion. Tighten any loose connections.
- Ventilation: Ensure the area around the inverter remains clear and well-ventilated to prevent overheating.
- Battery Inspection: Regularly check battery terminals for corrosion and ensure proper electrolyte levels for flooded batteries.
8. Troubleshooting
This section provides solutions to common issues you might encounter. For problems not listed here, please contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on | No battery connection, low battery voltage, DC breaker off. | Check battery connections, charge battery, turn on DC breaker. |
| No AC output | Overload, short circuit, AC output breaker off, inverter fault. | Reduce load, check for short circuits, turn on AC breaker, check LCD for error codes. |
