Multiplus-II Gx vs CCGX

Hi have in mind a system mixing PV battery and multiplus-ii Gx like this :

I have all components notice PV inverter are APsystem QS1, the PV power feed is measured by ET112 meter.

The grid current is measured by tore sensor.

Now i start to program my nice Multiplus-ii Gx box and i am facing to some issue:

1/ the ET112 meter is regonised but only as a grid meter there is no option to define it as a PVmeter (in the CCGX there is).

2/ there is no power related to the current sensor connected in the jack input

3/ thre is no menu to set ESS in mode 1, mode2, mode 3 (in the CCGX there is)

I use ESS 0176 programming

and set the french grid standart


Is multiplus-ii Gx realy equivalent to multiplus-ii + CCGX regarding this kind of function

What are the proper assistants to implement this

Hi @michelP,

It sounds like your access level is not high enough in the GX device, please confirm the access level you are using in the General menu of the GX device.

Trying to change these setting without the required access level will likely give you this message:

Q2 - Have you enabled the setting for External Current Sensor in VEConfigure? 7889-veconfig-sensor.jpeg

Q3 - You don't set ESS mode1, mode2 or mode3 exactly - they are listed as "External Control" in the ESS menu of the GX. This is explained in the ESS Mode 2, 3 manual.

I have just checked and they are there in the MultiPlus-II GX, as long as you have sufficient access level privileges. Settings access level is explained in this document (and the same procedure applies for the MultiPlus-II GX).

The exact variations between the GX card in the MultiPlus-II GX and the CCGX and laid out in this comparison table.

Hi Michael,

Your screenshot shows the System Setup -> System name menu.

The setting you are asking for is in the ESS -> Mode menu;

Can you confirm you are using the Victron supplied Current Transformer part?
