Monitoring with REFUlog
The REFUsol 08K ... 23K inverter can be connected to the monitoring portal REFUlog using direct Ethernet
connection to the internet, or via RS485 and the REFUcontrol data-gateway.
Once an internet connection is established, the inverter will automatically start to send data to REFUlog
every 5 minutes. The sending interval can be changed with the configuration tool REFUset.
To view the inverter data, open www.refu-log.com with your browser and login or register as a new user.
You can use the activation code provided on the type label of the inverter to assign one or more inverter to a
PV system.

converter.
For extended settings, you will receive a personal password on request from the REFU Elektronik GmbH
Service.
