Hi Matthias,
I try to set my Multyplus to use lithium but i need to update because my firmware is to old for supporting by the VictronConnect program and i need to upgrade to version 200 or above.
I was working with VEFlash but it came back withe to input an upgrade key.

Can you make some screenshots and a picture of the main PCB of your MultiPlus?

You want to update not upgrade.
So your problem is the error you get.

[Edit: You selected the wrong firmware file. Your device ID is 1909 so you have to select a firmware file that starts with 1909.
The highest FW you can install on your device ist 159 or 209.
The 400 and higher are only for the new processor starting with 26 or 27]

Do you follow the instructions step by step?

That’s what the VictronConnect manual also would have told you:

You need to use VE.config.

What exactly do you want to do?

I want my multi to use LiFePo4 batterie.
But now i can connect to VE configure ant hope that i can change the batterie settings.
I am new with Victron so i have to figure out a lot.
But I’am grateful of the input you have given me.

Good morning Matthias,
Do you know if i can use a remote panel on my older multiplus?
Like the digital multi control?
Kind regards,
Ger

I just found that the Victron Digital Multi Control 200/200A can be connected to an older multiplus.
