You MUST give each devicea unique address on the RS485 bus. Check the device manual for instructions.
Use lower addresses first (1, 2, ...) because the SmartgridOneController will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The SmartgridOneController will scan those first.
Go to “Main Screen” >> “System Settings” >> “Advanced Function.”
Modbus SN should be set to any number between 1 and 247. Do not select 0!! Note that if there are multiple devices on the RS485 bus, each should be given a unique number. This is the address.
Slave should be checked.
Only when an additional meter is connected directly to the inverter should “EX_meter For CT” be checked. If there is only a meter in parallel with the SmartgridOneController it should be unchecked.
Make sure the following settings are all correct: "Max A Charge", "Max A Discharge", "Grid Charge Ampere"
