How can I see both Grid and Generator on VRM

I have a cerbo GX and 2x 12/2000 Multiplus running in parallel

I want to be able to see both a.c inputs on VRM I'm able to see the generator and grid on vrm but not the AC input on the generator. Please help

What do you mean? MP only have one AC input, AC input 1. You assign the label to the AC input 1 in the Cerbo Settings > System setup.


Since you don't have a Quattro, you don't have an AC Input 2.


While you may have two inverters with two AC inputs, they are both AC input 1. Inverters in parallel are essentially treated as one big inverter.

@snoobler "much to learn you still have, my young padawan" :D

With the "VE.Bus System Configurator" the setting "Switch as a group" you can configure two MutliPlus to act like a Quattro.

@MAXTOSEA can you maybe make some screenshots? I'm not exactly sure what you are mean.

Yeah, but can you display them separately?

Depends on what/where you want to see it separately.

The VRM dachboard looks something like that:

But only one input can be used at the time and so you will also only see details of the active input.

Right, but those are the labels for AC input 1 and AC input 2, no?


The OP still has only AC input 1, but with switch as group, one MP can be connected to gen and the other to grid.

The input of the slave Multi will act like AC IN 2 of a Quattro.

Actually I just checked. With only two in parallel you don't have the "switch as a group" setting.
You just select single phase and the number of inputs. Than you put one Multi in input 1 and the other in input 2.
The lowest input number always has priority.

I saw it in email. Because that's in the Cerbo setup, not the inverter setup. Those values are there regardless of what you have installed.


I have a Raspberri Pi running Venus OS with only a battery BMS running - no inverter whatsover installed:

Again... I have a GX device and a battery. That's it. No charger, no MPPT, no inverter, etc.


This is the Cerbo setup, not your inverter setup. The system needs to be able to manage a Quattro, so there's a second AC input listed.

So if I do it the way Mathias is saying I still won't be able to see the Data individually correct?

If grid is connected to one MP and the generator is connected to the other MP, it sounds like it.


I would wait for @Matthias Lange - DE to confirm. :)

@MAXTOSEA I'm still nor sure what details you what to see where.

The System can only use one of the inputs at the time and the VRM dashboard only shows the active input.
