I have a one year Multiplus 24/3000/16-70 (large uC, 2612) with firmware version 423. I have just bought a second similar Multiplus with the intention to set them in parallel. The second unit came with version 430.
To set them in parallel, I will have to upgrade at least one of them to same version. But I tought "While I am at it, I might as well upgrade both to latest version".
So, now I stumbled on the doubt of what is the difference between firmware versions below and up number 450, as it seems there is a separation in the Changelog table.
I have search on the document:
but I couldn't see any reference to any difference in groups of versions inside the same family (4xx in this case).
Addittionaly, on Victron donwload page there are available both 433 and 459.
So, in the end, what is the right firmware for me? 433 or 459 and why are them both on site as the current versions?
