NOTE! If several FRONIUS IGs are interconnected with a datalogger and data
communication is to be performed, then each FRONIUS IG should be assigned
a different address.
It is important to assign a different address to each FRONIUS IG to enable the datalog-
ger to distinguish between the individual inverters. If there are two FRONIUS IGs with
the same address in the system, then data communication with the datalogger will not be
possible. A different address should be assigned to any FRONIUS IGs on which status
message 504 appears.
Important! If your version does not have a display unit, information on how to set the
address can be found in the chapter entitled “Installation”, section entitled “Design
without display: Set address”.
