Modbus TCP is enabled by default on Solis inverters
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
