4yo 48/3000 has updated software to V506
new 48/3000 II, added to run parallel to original, has updated software to V507, the two units won't talk because different software version. can't update past V506 on older unit & I don't know if it's possible to roll back software on the new unit
any thoughts?
If it runs 506 it will run 507..
How did you update it?
Use a mk3 and veflash, that will allow you to reflash either assuming you have the older file.
is it possible to reverse the firmware update in the newer unit, back to a 506?
I shut the inverter down, rebooted it and tried updating again from 506 to 507, message came up that I am on the latest version :(
You have several option still available to you.
Check your Victron connect is up to date. That is likely the issue here.
Update it over the VRM. This wil take you to 508 so you will then have to do both as individuals. Before programming.
To roll back you have to download the file from victron professional and flash it manually.
It is very strange that you updated one and then the other and they were both different. Would love to know the method you used. Was it different for both?
