Recently when I tried to update Multiplus-II 48/3000 firmware using VRM I noticed warning sign next to the installed version. I can't find what does it mean. Is it safe to proceed? I would be grateful for any comments.

multiplus-II firmware update warning
It is simply telling you there is a later version. Nothing more.
"Never change a running system"
Do you have any problems with your system? Do you need any of the new features in the new FW?
You can proceed if you want, but normally it's not necessary to keep all FW up to date.
Red is just a bad choice IMO.
From changelog:
xxx510
Added gridcodes: Czech, Poland
thus this is important change for me.
What do you mean by 'a bad choice', wrong firmware version or configuration? I'd like to be more or less sure I can do the update, or do factory reset and update if necesary.
I meant that the color red for that "warning" was a bad choice.
Users like you get confused.
If you need the new grid code than do the update but make sure to read the instructions carefully and follow them step by step.
There is also a video available that shows the update process.
Some of the settings of the MultiPlus are reset to default!
Very important that you read all the questions as you proceed with the update.
one of the important steps is that you ONLY use a industry standard machine (dont use a mac or android)
during the update a file is downloaded to your local machine, usually i nto the downloads foilder. this file is the original configuration setup of your multiplus.
once the update is finished this file must be opened and it will be converted to suit the new fw check the settings inside to make sure everything is as you want then exit the configuration software, and SAVE the file in the process .
Then go to device list and remote configure and upload the saved file.
If you dont do this step then the inverter is reset to default and the charge settings are set to battery voltage ie 12v so that no charging will occur until its corrected.
Its not hard to do but this step is important.
