Solis - Activate Modbus TCP

• When the Sourceful gateway connects to the inverter, it may interrupt the Solis dongle connection
• This means the Solis mobile app may not receive data while the gateway is connected
• Monitor your system through the Sourceful Energy mobile app instead

Locating Your Inverter

Choose one of these methods:

1. Use the IP Scanner in our mobile app to identify the inverter IP
2. Use your router's interface to find the inverter IP

Connection Details

Default Modbus TCP settings:

• Protocol: TCP
• Default Port: 502
• Unit ID: 1

Troubleshooting

Connection Issues

If you experience connection problems:

• Verify inverter power status
• Check network connectivity
• Ensure no other devices are currently connected via Modbus TCP
• Verify port 502 is accessible
• Test using Modbus diagnostic tool

Mobile App Access

If the Solis mobile app shows no data:

• This is expected behavior when the Sourceful gateway is connected
• Use the Sourceful Energy mobile app to monitor your system
• If needed, temporarily disconnect the Sourceful gateway to use the Solis app

Testing Connectivity (advanced)

You can follow our testing guide to confirm that a connection can be established. For Solis inverters, try port 502. The Unit ID is typically set to 1.
