I've got a few "quirks" with my AIO, and it's been suggested to me to get the latest firmware. I have previously done this through the portal, but the latest aren't showing for me.
According to this https://givenergy.co.uk/firmware-revisions/all-in-one-inverter/ I should be able to get up to
A620-D620, but I'm all the way back on A616-D616.
Can anyone tell me how I go about updating this?
