GX Tank 140

Good morning,

I read a lot about the GX Tank 140 converter box which could be used to read voltage or current sensors at the Cerbo GX. This box has been announced by YE 2020.

Any update on the availability of the converter box?

No Analog inputs shown on cerbo gx.

Originally was showing temperature and tank options in menus. While installing resistive tank sensors the cerbo GX rebooted. now all analog options are blank. The tank over view page shows no tanks connected and no options for temperature sensors available. How can I get those items to show again? It seems like the cerbo GX hardware may have faulted out.

ESS soft start


Is there anyway to allow ESS to soft start or to ramp up as the sun comes up?
Right now the logic seems like it waits to SOC is 5% high than minimum and then turns on and brings grid to grid setpoint. I would prefer that the system stays at minimum SOC and the inverter tracks MPPT out till the grid is at setpoint then start charging the batteries till 5% high then go back to normal ESS. This would prevent the system from doing the 45% on, 40% off, 45% on, 40%, that I sometimes have on cloudy days.

I have been able to do it with external control but would prefer if it was just done in the GX.


This is how it looks when running. Thanks

Solution to Cerbo GX Wi-Fi issue when having the GX Touch connected

Dear all,

This message is to inform about a Wi-Fi related problem in the Cerbo GX. Some Cerbo GX-es will not properly work on certain Wi-Fi networks when having a GX Touch display installed. If they do or not depends on the (channel of the) Wi-Fi network, and on how exactly an antenna cable inside the Cerbo GX ended up when manufactured.

Its obviously not good and I’m not happy with it, but it is what it is and you’re better off knowing all the details than not knowing them.

There are a few solutions, one is to simply send it back to your dealer; to have it repaired.

The other is to make the wifi network work on a one of a few specific channels; which don’t have the issue (details in the pdf)

And lastly, if you’re technical, you can fix it by opening the unit up and repositioning the antennas to make sure its cable is no longer close (or even touching) the hdmi connector or surrounding area.

Now, don’t get me wrong wrt the repair: you’re more than welcome to return it for repair. But still I chose to share the details of the repair as I can imagine that for some it will be the preferred option.

Lastly, my apologies! Especially to those who have spent a lot of time trying to find out why it wouldn’t connect to wifi.

And a big thank you to @WKirby who helped uncover the issue and even to find the solution. Warwick has been a great help in this.

All the best,

Matthijs Vader

Ps. All distributors and dealers have been informed about the issue via email.

Simple consumption report in A since last charge (engine, solar, genset, shore)

Hi. I am new to the BMV-712, Cerbo and VRM combination and the reporting possibilities. What I want is to see an simple report showing A used since the last time A was added via engine alternator, shore power, or solar. From what I understand, the BMV-712 Ah tracking counts A inn and out since the last full charge? With a report like this, I can track how many Ah my boat is consuming over time.

Cerbo GX connection to multiple MPPT not parallel

Hello everyone, I am almost confuse about to monitoring 3 MPPT Smartolar charge controllers that we are going to connect to the Cerbo GX. Because the solar installation is more than 20 years old, "unfortunately" we have 3 string of solar panels connected with 3 battery banks and after by schottky diodes to the load (MM.WW. system), but we can´t optimize the banks because the space of each one is limited to joint them on one battery bank. for that reason we should monitor each MPPT Charge controller separately. Is it possible to monitor each MPPT (PV power, BAT power and load consume) or each MPPT should be connected to a GX device?.

Thanks for your support.

which charger? World Voltage, Cerbo/BMS, higher amperage?

I need help selecting a Victron 12V charger that

  1. Can handle 120V and 230V power
  2. Can connect to a Cerbo and honor stop charge commands from the Cerbo (which in turn is listening to REC Victron Compatible BMS)
  3. I need relatively high amperage charging. 100a would be ideal.

Are there any devices that would work? It seems the Centaur doesn't communicate with Cerbo, and isn't programmable.

BTW, my absolute fantasy product is an inverter/charger that can plug into any shore voltage, but puts out only 230V. Sort of an transformer/inverter/charger.


I'm on a boat that uses shore power all over the world, so I need to be able to plug in to USA 120V and 230V everywhere else. I use that to charge my batteries, and use a a separate inverter using the batteries to provide AC house power to the boat. I currently have a Mastervolt Chargemaster 12-100 that handles any voltage. That works great, but now I'm upgrading to LiFePo4 batteries, and the Mastervolt doesn't have Lithium profiles, doesn't seem (???) to be programmable. It also will not connect to the Cerbo or Bms, so I can't send stop charge commands.

Intermittent VE Bus state OFF, no warnings. Lost power 30seconds

Any gurus out there have any ideas on this problem?

8kW Quattro, 7 x Pylontech Force 1, 2 x Blue Solar chargers commissioned this week. System ticks away quite nicely then randomly the inverter appears to switch off very briefly. Owner complains of losing power for around 30 seconds. Happened twice yesterday and twice the day before. Can see the event in advanced logging (VE Bus state briefly off) but no warnings generated. Rest of system unaffected. Doesn’t seem to correspond to anything unusual… no large loads at the time, etc. We’ve had storms the last day or two, not sure if this would be a factor. Anyone have any ideas??

Multiplus no longer connects to Cerbo GX after smart dongle firmware update

Tonight I was prompted to update the firmware on my Ve.Bus Bluetooth smart dongle connected to my Multiplus (it was stated as mandatory on my android phone). I used the app to install the update and now the Multiplus no longer shows up on my Cerbo GX as a connected device nor do I see it displaying any AC output power on the Cerbo screen when the inverter is on and providing AC power to my load. On my phone the Multiplus is connected, as well as all my other Victron products. I spend the night powering on/off all the components, including updating the firmware for the Cerbo GX from the touch screen and the BVM via the app. I also completely disconnected power to the Multiplus and still no luck.

Attached are images of my app and a picture of the Cerbo GX screen (which shows no inverter). And yes, the inverter is actually on despite what the app states.

All the devices connected to the app, including the Multiplus inverter/smart dongle.


(note that the inverter is actually ON despite the app stating it is OFF)


Stuck in an initializing state?

Cerbo + VE.BMS control of Multiplus?

Smalle Boat Electronics-12V DC System.pdf

I have installed a system on my boat with Victron Smart LFP batteries, a 120v / 3000w Multiplus, a Cerbo GX, and VE.Bus BMS. I pretty much just followed the schematics on the Victron site, and it is working great. I uploaded my schematic as reference.

Overall, I'm very happy with the system, but I would really like to be able to use my phone to change the Multiplus between Charge/Invert. I can set the current limit, but it won't let me set the mode. That is really annoying and I don't want to have to install the little control panel just to use the switch.

Another thing that seems to be missing is a way to disable the inverter at a certain SOC. I have just enough batteries to run my aircon for a few hours in the evening which is all I need to cool the boat down for a nice sleep. I know I can do that with the MK3 USB interface cable, but its so clunky. Sometimes I would like to be able to turn the inverter off at a different SOC and it would be really nice to not have to use the computer and cable for that.

So, anyone have any ideas on how I could achieve either of these two things?

Cerbo CX : Wrong solar power readings

Hi ,

Some background info . Starting to build my victron system slowly from the ground up.

I have 3 solar inverters :

- 1x Kostal piko 5.5 - 3 phase

- 1x Ginglong 2.9 Kwp - 1 phase

- 1x Ginglong 2.1 Kwp - 1 phase

I bought a Cerbo CX installed and 2 x ET340 and 2x ET112. To connect them I bought 4x RS385 industrial galvanic seperated converters and a powered USB HuB. The devices show up perfectly.


The readings where ok until I connected the last ET112 (Solis 2.9 Kwp) to the CerboCx.

I see my consumption on the AC Loads increasing as my power increases that comes out op my Solis 2.9 kwp inverter . As soon as I turn the solis inverter 2.9 kwp off , the readings on the AC loads are perfect .


Also for some reason we sometimes have a generator in there ? I don't have one and the readings are static . If I refresh the page sometimes and then it's gone ? UI bug ?

Please help . Any advice appreciated .

Cerbo GX Sensor Recommendations

I'm super excited to find that Cerbo GX can monitor my batteries, solar, AND tanks. My stock KIB sensors are nearly useless, reading 2/3 full until gray water starts coming up my drain, signaling 100% full. It's pathetic.

Does anyone know what sensors I can use that will give accurate level readings and work with Cerbo GX / GX Touch? I would like fresh, gray, black, and propane sensors that work with Cerbo GX.

Will this work? Do I really need 4 sensors for just the black tank?!? https://www.etrailer.com/dept-pg-RV_Sewer-pt-Probe_Sensors.aspx

Possible feature: Select time to discharge battery

Hi all!

I have a ESS grid paralell system (Victron Multiplus II 48/3000/35-32, Solaredge SE300H, Cerbo GX and Pylontech US2000C). Until now everything is working fine, it is charging the battery with the exceed of the PV inverter and then use the power of the battery during the non-solar moments). I see the option of "schedule a charge on battery" where you can select a time where you can charge the battery (per day, only once, etc), but I would like to know if it could be possible to select the other way around, select in which moment you want to use the energy from the battery -I read all the documentation several times and I don't see it, not sure if this is implemented now-

Why? In Spain, where I am living, at this moment we have two different electricity tariffs during the day (peak and valley), so in my case, I would like to use the battery especially during the "peak" tariff only and keep the charge if there is "valley" tariff (it is two times more expensive during peak than on valley).

Thanks in advance!

2x CAN interfaces on CerboGX

I've currently got a CCGX and have the CAN connection going to a Batrium BMS which uses the CAN-bus BMS(500 kbits/s) CAN-bus profile.

I'm considering installing a Fischer-Panda generator that I understand can be controlled with GX device although this will require NEMA2000 CAN-Bus profile, now I know that my CCGX only has 1 CAN port but I notice that the CerboGX has both VE. CAN and BMS CAN ports.

If I upgrade to the CerboGX can the Battrium BMS be put on the BMS CAN ports and the Fischer Panda on the VE. CAN port and they use different CAN-BUS profiles?

Cerbo GX Configuration

Hello community,

I have questions about my Cerbo GX configuration.

I have the following configuration, currently.

I have a Cerbo GX, a Phoenix Smart IP43 charger and a BMV-712 Smart.

If I am in Bluetooth reception range, then I can query everything directly, no problem.

Of course, I also want to know what the status is when I'm on the road.

I have learned that I can't see the Phoenix Smart IP43 charger when I'm on the road, so I don't know if there is no power connection. OK, I'll have to think of something.

But I would have thought that I would see more data from the BMV-712 Smart.

I have two batteries on it (main and auxiliary). However, I only see the main battery.

I made an extra VE.Direkt connection by cable, but no change.

I cannot add the BMV-712 Smart to the configuration in the Cerbo GX.

Enclosed is a screen shot of what I currently see.

Maybe someone can give me some tips on what I am doing wrong.

Many thanks in advance
