Remove GX device from account without full control.


I have been asked to assist with an installation done by someone else who has full control over the system in VRM.

Is there a way in which I can obtain full control over the system in lieux of the original installer providing such access?

V-TAC LFP batteries, trying to source information

There's a new distributor of LFP batteries in Europe for a couple of months now, under the V-TAC brand. V-TAC was founded some 20 years ago at UAE and has a very strong presence in Europe, particularly eastern Europe and the UK. They've been hard into the LED and lighting business. They've recently started offering LFP batteries for solar projects, along with other energy bundles of dubious quality. I am interested in their 10kWh model (model name: AT48-200H or VT-12040), since I can source them locally for under €250/kWh and they come with a full 5-year warranty.



According to the local distributor, the battery is made by Vestwoods, who are a quite well-known producer of batteries, however I haven't seen any in that form factor from them.

I am trying to figure out the model of their BMS and whether there is any chance of it getting along with an ESS GX setup, either officially or through Louis' excellent serial tool. Here's a photo of the BMS they are using, in case it rings any bells (searching for "CPES-BMS16S" online wouldn't produce any results):


They have published lots of documentation on their website for all models, and there's also a compatibility chart that displays Victron among the compatible brands; it doesn't mention to what extent, though.

I would appreciate any additional information or insights.

Here's the manual, including communication ports pinout

Faulty USB on Cerbo GX?

I have a Cerbo GX and with the upgrade which disables Bluetooth, I purchased a USB Bluetooth Dongle listed on the comparable list on the Victron site. However, it doesn't detect it (2 models tried).

I plugged in a USB Mouse but not even a red light on the mouse.
Is there a back door to activate/deactivate the USB ports and 5V? I feel I have a faulty Cerbo GX but wanted the communities feedback before opening an RMA as it's about to run out of warranty I fear.

Cerbo GX touchscreen won't turn on Multiplus via RJ45 cable

My Cerbo GX touchscreen will not turn on the Multiplus via the RJ45 cable after I turn it off from the Cerbo Gx touch screen. It seems to lose the connection. With the multiplus in the inverter mode, If I manually disconnect the RJ45 cable and connect again, then I regain the connection and able to operate the Multiplus. Once I make that connection, I am able to operator the Multiplus from the Cerbox GX touchscreen and as long as I don't turn off the Multiplus from the Cerbo GX, it stays connected but once I turn off the Multiplus with the Cerbo GX, I lose the connection and can not turn back on the Multiplus unless I unplug the RJ45 cable from the Cerbo and re-connect. Any ideas on how to fix. I have re-booted my system several times, I have the most current firmware.

Multiplus II - GX . Wifi connection

Good day to all . Just received a Multiplus II 48-5000-40 GX to install . I thought the previous ones were coming with a little antenna to connect to the top . But anyway, it seems this one does NOT connect to a wifi network UNLESS I add a wifi module ? Does this unit REQUIRE such a wifi module ? Thanks for the update from those who know ! P.S. Came with a "regular / Not GX" manual !

Cegasa SolarGreen configuration with Cerbo GX

Has anyone successfully configured a Cegasa Solargreen battery system to a GX device.

I cannot get the Cegasa to appear on the device list of the Cerbo?

The system consists of 2 X Cegasa Solar Green 5160, 1 X TCC CAN, 1 X Cegasa Hub Com, 1 X Multiplus II 48/3000, 1 X Cerbo GX, 1 X GX touch. ESS system.

The Firmware version on the Cerbo is 2.93. The TCC CAN is not a v02 - does it need to be?

I have tried a number of TCC CAN unit and hubs?

Please get in touch if you can help.

Has DC System - Incorrect Consumption in VRM when Phoenix Inverter is run on DC

Hey everyone,

I am running an off-grid system with a GX Device and an MPPT, BMV and Phoenix Inverter 12/800. I also have DC loads connected to the system. As long as the inverter is not running, the consumption values in VRM are perfectly valid, but as the inverter runs, the values measured are off, as the inverter power is just added ON TOP of the DC Load Power which already includes all the current drawn by the inverter.

Is there a way to configure the GX Device to ignore the AC Power measurements, as they are already included in the DC Load? If not: it'd be great to have an option in the menu that states that the inverter is run on the DC system. Otherwise I am unable to reliably log the system consumption...

Phase rotation, there are no more than 6 variants -> the warning comes with everyone

To anticipate it, the installer yesterday checked the wiring. From the house connection via the MultiACin via ACout to the loads, the same cable colors are never crossed. 35m 5x16mm² underground cables were laid from the house to the MultiPlus and back. Since no error was found, Ve.Configure tried all 6 ways of assigning the phases:

1-2-3, 1-3-2, 2-1-3, 2-3-1, 3-1-2, 3-2-1 for all there was a phase rotation warning if the MultiPlus tried on the grid back.

Three-phase motors have the correct direction of rotation both in inverter operation and in mains operation (manual switchover possible via switch). We have no idea

GX or not GX

I'm planning to install a new system with a multiplus-II 5000 but I think that power will be not enough within some time (in a 2 years time frame). I'm planning to pass to a parallel configuration in two years. I will be able to add additional PV modules and batteries (Pylontech) and use more power and also to have a level of redundancy

Considering that is possible to have only a GX device what do you think is the better option:

1. Install now a multiplus-II GX now and then install a second multiplus-II GX, disabling the GX part

2. Install now a Multiplus-II and a Cerbu GX and the install another Multiplus-II

3. Install now a Multiplus-II GX and then, in parallel a Multiplus-II NO-GX

4. Redundancy is not required, use a Multiplus 8k or 10k now and a Cerbu GX and upgrade only batteries and PV modules


Kind Regards!
