Hi All,
I have a Multiplus-ii 48/5000 which was purchased mid 2022 (Serial No. HQ2203xxxx). I decided that I wanted to purchase a 2nd unit to operate in parallel, and purchased a 2nd unit (Same part number) in Jan this year (Serial HQ2237xxxx).
Since making the purchase, I have now read in the Victron Parallel document that all parallel units need the same VEBUS Firmware. Checking my existing unit, I can see its 2623500, but I am concerned that this newer unit may not match the same VEBUS firmware version.
So....
Question 1.
Is there a way I can tell the hardware revision from the outside of the box? The stickers do not appear to indicate the hardware revision.
I am reluctant to open the box to read the VEBUS Firmware, as there is still a slim option that I can work with the dealer to exchange it.
Question 2.
Can the hardware version be calculated from the Serial Number?
You would assume there must be a specific week where the Victron factory updated the hardware on the assembly line. And with the serial number showing the Year/Week we should be able to work it out
Question 3.
Does anyone here have a Multiplus-ii 48/5000 unit purchased recently that can share their Year/Week & VEBUS Firmware version (Visible on the CerboxGX Screen)?
Thank you in advance,
