Communication via RS485
For monitoring via RS485, you need to use REFUcontrol device to forward data to the monitoring portal
REFUlog.
You need to assign an unique USS address to each connected inverter.
Addresses:
1 to 31
This address is required for communicating with the inverter via RS485.
After entering the address, restart the inverter to activate the new address.
Protocol type:
1: REFU USS protocol (preset)
2: (not used)
3: Meteocontrol USS
4: Modbus RTU Sunspec
(address 0 cannot be used – address 0 is automatically set to address 1!)
5: Multimode USS / Modbus RTU Sunspec
(in Multimode, you cannot use USS address 0 and 2!)
Baud rate:
57600 (preset and recommended)
115200 (for short RS485 networks)
Parity:
even
Handshake:
no
Data bits:
8
Stop bits:
1
Protocol:
REFU USS protocol

Portal Monitoring
To ensure the inverter sends data via Ethernet to the REFUlog monitoring portal, the portal monitoring must
be active.
Open Menu Configuration > Portal Monitoring and enter the following value:
0 = Portal monitoring via Ethernet not active
1 = Portal monitoring via Ethernet active
Notice
If the inverter is connected with RS485 to REFUcontrol, the setting 0 (Portal
Monitoring via Ethernet not active) must be used!
