After updating the multiplus-ii 48/5000 GX to 568 via the VRM Portal, the inverter is in “off” mode; it does not start up and does not appear in the device list. It also shows “off” status in charger mode.
Sounds like something went wrong during the update, you might need to use a MK3 interface to install the update again via VEflash or VictronConnect.
It’s interesting that it generated a document with the internal settings—in other words, the update went well, but now it’s no longer possible to upload a new config without MK3 because the status is OFF.
Hello,
Is there any benefit to upgrading the MultiPlus-II 5000 GX from firmware version 560 to version 568 ?
If you have to ask, the answer is always no.
Obviously not.
There can always be a problem during the update, the chances are low but not 0.
That’s one of the warnings that come up before the update starts.
Try to disconnect everything from the MultiPlus that is not needed.
You could also try to open the MultiPlus and disconnect the internal VE.Bus connection between the GX module and the MultiPlus.
I tried connecting to the inverter via the MK3, but there’s no connection. There’s also no power at the inverter’s output. Ve.flash doesn’t help, and no other utility can detect the inverter either.
Do you get an error in VEflash? At which step it fails?
VEflash is usually the last resort to recover from a failed FW update.
Yes, the flash indicates a communication error with the inverter when the inverter needs to be turned on and the flash is supposed to establish a connection.
You can try pop the cover, disconnect the internal GX and attach the MK3 to it’s connection. That used to be a thing back in the day - the GX and mk3 clashing.
That’s a good hint.
It can happen sometimes that the GX device is messing with the MK3 communication.
Normally that shouldn’t be a problem but in a situation like that it’s worth a try.
If that doesn’t help either you need to contact your seller/installer for the next steps.
