Multiplus firmware-can't update

Multiplus firmware update.

Current firmware is 2702413.HEX20210505-144831.jpg

I am using Victron Interface MK3 to USB (tried on 2 different computers, run as administrator and normal) Windows 10.

Port is autodetected for MK3.

Follow steps...

I have tried different patch cables.

Is this Multiplus not update-able?

I have tried 2702433 and 2702481. No success.

I have it connected to the Cerbo Gx on the VE.bus. I have read that it cannot be updated online through the Cerbo GX yet. The muliplus is working fine.

However, I also have the VE.bus Smart Dongle and it won't connect with firmware below 415.

I want to have multiple options for connecting to maintain the Multiplus.

I have read posts on this forum of successful firmware updates, but detailed steps were not given.

I have switched off... reconnected... tried both newer firmwares... 2 different windows 10 computers... different patch cables...

Is your Multiplus detected in VE.Configure 3?


Did you disconnected the inverter from Cerbo GX first?

Try to disconnect the Cerbo during the update.

I use VictronConnect to update the firmware on my Mulitiplus with my MK3 to USB.
