How Can We Help?
As of this writing, one is not alerted when there are new Fronius software updates to install. Until Fronius implements that ability, Fronius customers should check for software updates on a monthly basis.
To check for Fronius updates:
- Login to your Fronius portal
- Navigate to Inverters via the top/menu bar
- Look at the update section to verify the software build you are on and to see if updates are available.
If you do find that a software update is available, here are the steps you can take to install it using a USB or flash drive:
At your computer:
- You will need a large flat head screwdriver, a USB stick and a computer connected to the internet to download the firmware update.
- On your computer visit fronius.com
- In the top right hand corner click on Download Search
- In the search panel type in USB update
- The results will pop up, click on SOLAR ENERGY
- On the left hand side select your country as a filter
- Click on the appropriate firmware download for your model of Fronius inverter
- Open USB folder and delete any files / folders that may be present
- Copy latest Fronius USB Firmware to USB stick
- Eject USB stick from computer and go to inverter
At your inverter:
- Undo screws holding lower gray cover onto inverter
- Remove cover
- Insert USB into inverter USB slot
- Go to Settings Menu
- Go to USB
- Go to Software Update
- Press Enter a couple of times on the screens showing firmware changes
- The inverter will copy the files, update and restart
- When the inverter had restarted go back to Settings
- Go to USB
- Go to Unplug USB Device
- When the screen shows OK remove the USB stick
- Close the inverter cover back up and reinsert the screws and you’re away!
