Maintenance
When the inverter firmware is updated by the
manufacturer, this can be done on-site. In the process,
various hardware controllers are brought entirely up-to-
date. If an update is available, you will find this on the
manufacturer's website in the download area under
Service.
Procedure
1.
Download the software update for the inverter from
the manufacturer's website.
2.
Go to the folder with the downloaded ZIP file.
3.
Extract the ZIP file.
P
The files are extracted into a separate folder. In this
folder you will find the update and important addi-
tional information on the current firmware update.
4.
If the inverter is not yet connected with a PC via LAN,
connect this with the inverter now using a LAN cable.
5.
Start the update by double-clicking on the *.exe file
and follow the instructions on the PC.
P
The update may take up to 30 minutes. This time is
extended if the update is interrupted. Following the
update, the message "Update successful" appears
on the display of the inverter.
IMPORTANT
INFORMATION
In order to carry out the update,
enough PV energy for approximate-
ly 30 minutes must be available.
The update will otherwise be inter-
rupted or even cancelled. For this
reason, only carry out the update
during the day.
DANGER

CAL SHOCK AND DISCHARGE!
Always de-energise the device
during installation and before
maintenance and repairs, and
secure it against being switched
back on.
