Software Update - Fronius Primo serie Serviceanleitung, Ersatzteilliste

If a serial arc is detected, the power is switched off and the grid power feed operation is
interrupted. A state code is shown on the display. The state code on the display must be
manually reset before the grid power feed operation can be resumed.
The power shutdown also extinguishes the serial arc.

Software Update

The USB stick can be used even by end customers to update the software of the inverter.
The update file is saved to the USB stick beforehand and transmitted from there to the in-
verter, and the update process is started by going to the SETUP menu and selecting USB.
The update file must be located in the root directory of the USB stick.
NOTE! This product is equipped with a communication interface in line with the
"Communication Signal for Rapid Shutdown - SunSpec Interoperability Specifica-
tion". Power optimizers and other MLPE features in the photovoltaic system can
impair the correct functioning of the arc detection/interruption. When using these
kinds of components, the system installer is responsible for ensuring the correct
functioning of the arc detection/interruption. Contact your Fronius Technical Sup-
port for more information.
