Ensure both the SmartgridOne Controller and the iWell Cube battery are in the same IP subnet
(e.g. 192.168.1.xxx) and can communicate over port 1025.
The iWell Cube Modbus TCP interface is active only when the battery system is powered on and initialized.
Do not connect to inactive units or during firmware updates.
