How do you parallel a 5kVA inverter?

Paralleling two 5kVA inverters involves carefully syncing their outputs. Let’s break down the process with additional technical information in an easy-to-understand manner:

1. Check Inverter Specifications:

• Inverter X:
  • Voltage: 220V
  • Frequency: 60Hz
• Inverter Y:
  • Voltage: 220V
  • Frequency: 60Hz

2. Verify Compatibility:

• Ensure both inverters have the same output voltage and frequency. This ensures a harmonious connection.

3. Parallel Connection Kit:

• Check if the inverters come with a parallel connection kit provided by the manufacturer. This kit simplifies synchronization and load sharing.

4. Manual Synchronization:

• If no parallel connection kit is available, manual synchronization is necessary.
• Sync Output Voltages:
  • Adjust the output voltages of both inverters to be identical, which is 220V in this example.
• Frequency Synchronization:
  • Ensure both inverters have the same frequency output, which is 60Hz in this case.

5. Load Sharing:

• Distribute the connected load evenly between the two inverters to prevent one inverter from being overloaded while the other is underutilized.

6. Manufacturer’s Guidelines:

• Always refer to the manufacturer’s guidelines, user manual, or technical documentation for specific instructions on paralleling 5kVA inverters.
• Manufacturers often provide detailed steps and precautions for parallel connection.

7. Protective Measures:

• Implement protective devices for overcurrent and overvoltage to safeguard the inverters and connected devices.

8. Monitoring:

• Regularly monitor the performance of the paralleled inverters to ensure they are operating efficiently.

9. Capacity Considerations:

• Be aware of the combined capacity when paralleling inverters. In this case, the total capacity would be 10kVA (5kVA + 5kVA).

By following these steps and considering the technical details provided by the manufacturer, you can successfully parallel two 5kVA inverters, increasing the overall power capacity and reliability of your inverter system.
