Hi,

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?

Regards

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

VT-12040 - manual.pdf

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.

Thanks

Hello I want to use the Cerbo GX with GX touch 50 in a place without internet connexion, there is 50 meters between the screen and the Cerbo GX, is it possible to work with bluetooth or with cable connection. ? Thanks for your answer.

I just added the GX Touch 50 to my Cebro GX. The display is very large on the Touch 50. How do you adjust the resolution so that it fits on the screen?? I can't find anything in the manual.

Thank you.

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.

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 !

Can a Smartshunt connect to a GX device via VE-direct and simultaneously connect to a Globallink via bluetooth

Since 6 Month i have the problem, that my plant get the Error code: #67 - No BMS.

This only happens when the Batteries getting full (100 %). After this Error the Charger turns the PV Panels complete away and i have no more charge.

The plant is running but without the pv panels. The only thing i can do is to reboot the plant and after the reboot everything ist ok.

MultiPlus-II GX – v 2.73

MultiPlus-II 48/5000/70-48 – v 481

SmartSolar Charger MPPT 250/60 – v 1.59

BYD Premium LV battery – v 1.20

When it's working:

After the Error:

Maybe someone can help me with my problem, cause my plant is a pv off-grid photovoltaic system and iam not constant there.

Thank You and greetings

Bonjour Chers Victroniennes et Victroniens,

Quelqu'un a-t-il déjà eu besoin de déporter le GX Touch dans un autre emplacement que celui où se trouve le CERBO?

Utilisation de rallonges HDMI-HDMI + USB-USB ou bien via KVM IP?

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.

hi having a nightmare i have fitted 10 of these with out to much trouble but now the cerbo will not allow the 000000 pin just keeps asking to par with device i have tried a new phone tried to reset but no luck the only thing wi have changed is the BVM712 for us is a wast of time so gone for the tbs made one with no bluetooth but cant see how this would affect it is there any way i can conect via usb to change the pin many thanks

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...

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

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

Thanks!

Kind Regards!
