Multiplus-2 does not appear on victron connect

Hi all,

I am trying to update the firmware of my easy solar-2 GX 48|3000|35

I am using CAT5e (connected to one of the VE.bus ports) and Mk3 to USB to connect on my windows computer. When I open my victron connect app on windows laptop, on the device list page, in LOCAL section all I can see is EasySolar-2 and not multiplus 2.

What do I need to do for it to appear on victron connect?

I also looked online and found old method of firmware update using veflash. I can not find where I can download veflash anymore?

Please help

best to download the VE configure software and then use the VEflash if the victron connect does not work.


anyway you should not play with the software fw unless something is not working.

A Multiplus II GX unit really has two units inside. A GX venus device and a Mulitiplus II device with a VE-Bus connection

so there are really two fws,

1 for the GX device this firmware IS NOT updated by the MK3 unit. use your web page and connect to the unit via wifi or lan cable or bluetooth (depending on model) then for the GX unit select settings then firmware and then check for updates.


The multiplus II units FW is updated via the MK3 or via the VRM and remote devices

suggest you look around and find some Victron PDFs on how to do this,

lots of other info as well like you tube videos etc

I recently connected the Multiplus II 48v/8000VA110Amps to the CerboGx. However try as I may I can’t see the device in local or via VRM. I have changed different cables but to no avail. Any ideas? @Paul B

Yes I have a victron cable from the multiplus to the cerbo Ve bus port. I can send photos but essentially I see the Pylontech batteries, the BMV, the charge controller. Just not seeing the multiplus

@Matthias Lange - DE I don’t see the option to do any modifications to the multiplus. I just don’t see the Ve.bus /inverter on my cerbo gx. Any idea why?

Can you make some screenshots of what you see?

Did you read the 2nd link I posted? There is also a video.

@Matthias Lange - DE see attached screenshots. The inverter keeps showing as Off. so I can’t get any data from it or control it from the Portal. It also is not integrated into the system so it does not turn off the batteries at low SOC or voltage.
