Does your Galvo, Primo, Symo or Eco solar inverter require a Fronius USB update? If your inverter hasn’t been updated for a while it’s not a bad idea to run a firmware update via USB.
Why Fronius USB Update?
There are a number of different reasons that you would perform a Fronius USB update as follows:
Rectify issues with bugs in the existing firmware (not bugs of the creepy crawly kind mind you – we’re talking glitches in the inverter firmware)
Improved inverter performance
Improved inverter safety
Amendments and improvements to the existing firmware
As can be seen all these points are going to be beneficial to you, so why not watch the following video and see how to perform a Fronius USB update on a Galvo, Primo, Symo or Eco Fronius solar inverter? It’s not too difficult to do yourself if you follow the instructions on the video.
Fronius USB Update Steps
Please complete the following steps in order:
At your computer:
First off you need a large flat head screwdriver, a USB stick and a computer connected to the internet to download the firmware 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!
