Hello,
I’m planning to buy a MultiPlus and am undecided between a MultiPlus GX and a MultiPlus with a separate Cerbo GX. Can the communication module in the MultiPlus GX do the same as the Cerbo GX, apart from connecting a display? I don’t really need that anyway, as the device will be in the garage.
Does Node-RED also run on the MultiPlus GX? Will I be able to connect an energy meter, MPPT or an additional MultiPlus without GX to it later on?
Thanks.
If you are planning to expand at any point then an external device is better - they have more memory, typically more speed, and more ports for adding devices.
You won’t save a lot by having a built-in GX but will limit your options.
Hi, I had a MultiPlus-II 3000 GX, initially as a standalone unit and later in a three-phase setup (one GX and two standard units), with six MPPTs, multiple energy meters and Pylontech batteries.
Our current system has three standard 5000s and a Cerbo. The system runs perfectly in both configurations. One advantage of the Cerbo, in my opinion, is that it has more connections and slightly more options for input and output contacts.
If you buy a MultiPlus GX now and add a second or third unit later, that is possible provided their hardware IDs match. If they do not, you will have to buy two or three new units, one of which could possibly be a GX model again.
With a separate Cerbo, you can reuse it in any case.
Yes, Node-RED can also run on an MP2 GX, but if you want to do a lot with it, I would choose a Cerbo with more processing power.

I also started out with a Multiplus II 3000 GX and an additional USB hub.
USB is not galvanically isolated, so please bear this in mind.
I have some fairly large flows in Node-Red and have occasionally experienced reboots. I was able to partly resolve this by increasing the Watchdog timer setting.
This also applies to the new MK2 (a faster MK3 is coming, so it’s on my list).
The advantage is that it’s cheap and you don’t need a DC connection.
Because the GX is built in, it deterred me from carrying out upgrades regularly (which isn’t really necessary if it works, and is even discouraged by Victron).
For development, I used several Raspberry Pis that I still had lying around.
Thanks, the overview you shared was exactly what I was looking for. So I’ll go for the internal one, as it can do virtually the same and everything I need. The memory and processor are the same as those in the Cerbo GX, so it can run Node-RED.
Half the memory, different CPU.
Just look at which interfaces you need.
I like the GX device series for small installations because it requires less cabling.
Not everyone needs all the interfaces provided by the Cerbo.
It works wonderfully with an ESS system.
Do you know yet which power version you’re going to buy?
