We are pleased to inform you that the AutoUpdate function is now available for our complete series of coolcept fleX XL inverters.

You can choose between ‘Manual update’, ‘Information about new updates’ and ‘Automatic updates’.
How do you activate ‘Automatic updates’?
1. For new installations on devices that have already been factory-equipped with UI01.18, the system update method is queried during the initial commissioning.
In this case, ‘AutoUpdate’ will already be marked by default and only needs to be confirmed.
2. Activation via the display menu under ‘Settings < Updates’
3. Activation via the web interface in the ‘Update’ field

Please note:
- Existing devices first need to be updated manually to the new UI01.18 as usual. Afterwards, you can select the update method.
The procedure is described in a separate document, which you can also find in the download area on our website.

We recommend activating ‘Automatic update’!

Benefits:
For end customers: Never miss an important system update for your coolcept Flex XL inverter again!
For installers: Save time! You no longer need to travel to end customer sites for important updates.
