4. Setup and Installation

Proper installation is crucial for the inverter's performance and safety. Follow these steps carefully.

Installation Sequence:

1. Connect the Battery: Ensure the battery bank is correctly wired and secured.
2. Power On the Inverter: Once the battery is connected, turn on the inverter.
3. Activate Switches: Activate the PV (photovoltaic), grid, and load switches in this order.

Shutdown Sequence: To power down the system, follow the reverse order of the installation sequence.

Important Note for Inductive Loads: For inductive loads such as motors, ensure that the starting power requirement is at least 3 times higher than the inverter's nominal power to prevent damage or malfunction.

WiFi Module Installation:

The WiFi module is optional and allows for remote monitoring. Refer to the separate WiFi module instruction manual for detailed installation steps.

5. Operating Instructions

The inverter offers flexible operating modes to optimize energy usage.

Hybrid Charging Modes:

You can select from three optimized charging modes:

• Solar Priority: Solar energy is used as the primary source to charge the battery. The utility grid will charge the battery only when solar energy is unavailable.
• Solar Only: Solar energy is the sole charging source, regardless of grid availability.
• Mixed Solar/Grid: Both solar and grid power can charge the battery simultaneously, ensuring continuous power.

Dual AC Output Function:

The intelligent dual AC output automatically manages loads. In situations where the battery is low and neither grid nor PV power is available, the inverter will deactivate the primary circuit to conserve energy. The secondary output will remain active to power essential loads.

Remote Monitoring:

With the optional WiFi module, real-time remote monitoring is available via a dedicated mobile application. This allows you to check production, consumption, and system status from anywhere.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter.

• Keep the inverter clean and free from dust. Use a dry cloth for cleaning.
• Ensure all electrical connections are tight and free from corrosion.
• Periodically check the ventilation openings for obstructions.
• Inspect cables for any signs of wear or damage.
• For any internal maintenance, contact qualified service personnel.

7. Troubleshooting

If you encounter issues with your inverter, refer to the following general troubleshooting tips. For specific error codes or persistent problems, consult the full product manual or contact support.

• No Power: Check all circuit breakers and ensure battery connections are secure and charged.
• Low Output: Verify PV panel connections and ensure they are clean and unobstructed. Check battery health.
• Overload Warning: Reduce the connected load. Ensure the total load does not exceed the inverter's rated output.
• Over-temperature Warning: Ensure adequate ventilation around the inverter. Clear any obstructions from cooling vents.

The inverter is equipped with multi-layered protection features:
