Dumb question - I have 2 AC300’s and the menu is slightly different between the two. I checked the firmware updates and both are identical except for the HMI. One is HMI version 6029.12 and the other is HMI version 6029.09. There is no way I can see to update the HMI. It’s not a huge deal, just seems strange. The place I saw the difference is in the screen where I can adjust the amps for AC charging. One menu had some pre-set numbers you could choose and the other opened up a screen where you would only be able to type in a value. Maybe I’m OCD, but I want the to be the same (ha ha). Is it the HMI version that would correct this?
You may be dealing with two different hardware versions.
@rickwagner50 I’m sorry the HMI version can’t be upgraded. The factory version is different, so the HIM version is different, which generally does not affect the use.
