Cerbo GX Bluetooth connectivity limits

Hi I’m planning to get Cerbo GX and a GX Touch 50. Installation will be on a Sailing boat.

I already have an MPPT Snartsolar 100/20. I am planning to get also a smart shunt and use it to monitor two different battery packs.

First question: I want to connect the MPPT and the shunt using their Bluetooth capabilities. Is there some limitation in terms of functionalities compared to the cable option?

Se con question: I mentioned that the smart shunt should monitor two battery packs (two batteries for “house load”, one to start engine). I would like also to have a temperature sensors. Is there any Victron products that can use Bluetooth to share the data with the Cerbo GX? Or would be better to get two shunts and use the port for the temperature sensor? In this case I would have more questions to understand if temperature info is shared to the Cerbo and how the two shunts are displayed.

Thanks a lot!

MPPT 150/100 Bluetooth connection issues

We have installed our MPPT 150/100 in 2017 and have always experienced problems with the bluetooth connection.

Problems vary from not being able to connect by getting stuck on the connecting at different percentages, name shown on app displays the symbol & or a dot but never the actual name given to the device. On the few times we can actually log through the app it only gives us the current status of the mppt but never displays the 30 day history or shows the drop down menu for settings etc.

We monitor the MPPT via the VE.Direct 1 port on the color control

Currently installed firmware version v1.46

blue power control "no connection"

The blue power control doesn't "see" the multiplus anymore. I am using the EasySolar 48V which includes the color control.

Used to work, not anymore.

On the blue power control it say's: "no connection"

I checked already:

- power is OK

- tried another RJ45 cable

- jumpers are set correct (J2)

- correct Bus is used (VE.Bus on the blue power control connencted to the color control VE.Bus)

- color control firmware is the newest: V2.6

- multiplus firmware is the newest: 430

What can I do? Thanks for your help!

Bluetooth connection impossible

I own a SmartSolar 75/15 without any issues so far, with the device or with the Victron Connect App.

Lately, I can't connect my phone (or another phone, both Android) to the App. The device appears on the list, but when I click on the device, the progress bar goes to 20%, then back to 1%, and so on until the message "unable to connect blabla" appears.

I've also tried to reset the PIN with the PUK code, and still an errors shows saying unable to reset the PIN number.

On top of that, the device seems to work correctly as the bulk blue led is steady while the panels are at sun.

I've of course installed/uninstalled/cleared cache of the app several times, and the latest version was used.

Thanks for your time,

Connection issues with MK3 and laptop

Trying to use the Config software with the MK3 USB connection. I have downloaded the drivers to my laptop but I don't think they are installed correctly. I can't get past the finding a com port, the software times out and just gives me a help box. I know the MK3 is working as well as the RJ45 cable because if I connect it to my cerbo GX the Multiplus appears on the color control 50 display.

Can I set the charging currents any other way or is this the only way to set the Multiplus up for my new Battle Born batteries ?

Improved Bluetooth Range Recommendations


I have installed the 712 smart battery monitor and 100/50 charge controllers. I use my phone with bluetooth and it works well. My issue is the overall range on charge controller which I think is from everything being the basement of my 38 foot coach. I can literally be 10 feet from my coach and get no connection to the charge controller.

Can I add the bluetooth adapter and move up higher where there is less interference? What other options are good for my setup? I was thinking global link to solve all things related to connections? (assuming I've got cell coverage)

Smart BatteryProtect 65A no Bluetooth?


I recently purchased a Smart Battery Protector 65A for my 12V System in my Van. After installing it I wondered that it never showed up in the App under Bluetooth devices nor in the Victron App (iPhone SE using iOS 13 and also tested macOS)

After a quick google search I did reset it (more than once) according to this solution which apparently did work:

The device lets me select the voltage settings with the numbers on the display (1 to 9 or -, I set it to 8) and the output voltage is working, but still no Bluetooth. The mentioned settings, with grey background in the manual, in Mode "-" just shuffles through and even though I stop for example at F (enable bluetooth) it just keeps shuffeling.

Am I doing anyhing wrong here or how is the diveice supposed to work? I thought its kinda plug and play after installing and all the settings can be done via bluetooth - but I keep on sitting in front of the device and try to get bluetooth to work.

I apreciate any help and input!

SolarSmart MPPT 75/15 Bluetooth unable to Connect past 60%


Today in the mail, I got a brand new MPPT 75/15

It's all connected up and ready to go.

However, both my boyfriend's android phone and mine are unable to connect to the device.

It hits 60% and then stalls.

I have tried power cycling both the MPPT and the phones, I have unpaired the devices.

I have attached a copy of the log report from the app VictronConnect_report.log

Any advice would be helpful, I am unsure what to do at this stage.

Cerbo GX wifi issues

I have had my Cerbo GX with touchscreen installed in my motorhome for a couple months now. Most of the time it won't stay connected to my WiFi, which is about 8 ft above it. I use a Pepwave Max Transit Duo WiFi modem, so it's a pretty strong unit and the Cerbo shows around 75-80% signal strength. I can force it to connect, and sometimes it stays connected, sometimes it doesn't. Even when it's connected, I can't connect to the remote console much of the time. I'm on Firmware 2.57. Any suggestions?

Bluetooth Pairing with new iPhone

I have a MPPT 75/15 (HQ1811NTQ3F”) connected to a single battery and a single solar panel. With my iPhone 6 I could connect via Bluetooth using the VictronConnect app. With my new iPhone 11 I cannot pair with the controller. The app recognizes my controller and requires that I “enter the code shown on my “SmartComtroller HQ1811NTQ3F”. I cannot find any code either in the front panel of the controller or in a window on the phone. I have entered my 6-digit pin but it was not accepted. I have removed and re-downloaded the app with no effect. The blue led on the controller is flashing, showing a bulk operation.

Bluetooth issue with VictronConnect v5.35

I believe this started with 5.35 (Android), but perhaps something else. I have two SmartSolar 250/100s and a 150/35, and today when I attempted to connect they all say connecting, reach 80% then ask for the PIN code? I've not changed the PIN code from 000000 on any of the devices and that code no longer connects, just keeps asking me for the correct PIN.

VictronConnect says MPPT is connected to another device?


I have a VictronConnect MPPT 100/30 charger which has been great. I’ve been using the app without problems until a week ago when I started to experience an error saying that I could not connect to the charger because the charger was connected to another device. There are no other Bluetooth devices on the boat (I’ve searched high and low) so the result is that the charger is “grayed out” and I can’t monitor performance or go in to try and reset the PIN code or anything. Any ideas on how to connect to the charger with the app or to reset the Bluetooth on the charger itself?

Thanks for any help!

Bluetooth Connection fail at 20%

I've got a couple of devices now (Smart Battery Protect 220, bluetooth dongle and 160AH LFB battery) that have locked up while connecting. They all get to 20% then freeze and say connection problem. I eventually got back into the battery after some mystery combination of reloading the app and time going by, but haven't gotten back into the dongle or battery protect.

I'm getting gunshy now. When the app slows down at 20% I wonder if this will be the next one to fail. I've seen others having this issue with MPPTs, but haven't seen any real solution.

Anyone got any ideas?

Another SmartSolar bluetooth connection problem

VictronConnect_report.logI have a SmartSolar 100/30, and it has easily connected with my iPhone SE in the past with bluetooth, but now it is not. (Its now running iOS 13.6.1). Reading the manual, it suggests that if there is a blue tooth connection problem, to disconnect the controller and hook it back up and try again. I did that and no luck. Multiple times. I also noticed I had a slightly older version of the VictronConnect app, but i've updated it to the latest (v5.34) and it also does not work. I've tried quitting the app and restarting it, I've tried turning off the phone and restarting it, and none of those ideas work. There are no other devices turned on (like an iPad) that could connect with the device. Based on the blinking LEDs on the case of the unit, and voltage during the daytime, I believe it is working properly. I've attached a VictronConnect log if that helps. Can you help?

Can I use the temperature information that is shown by my Smart Lithium Batteries in a VE-Network (Cerbo)?

Hi all!

I installed two brand-new 200ah 12V Lithium Smart Batteries from Victron in my van. Those new one come with Bluetooth connection. Via the Victron smartphone app, I can check the temperature of each battery. Now I was wondering if it is possible to provide this information to my Cerbo GX or Smart MPPT. I know that the Cerbo has several temperature sensor inputs for cable sensors. But hopefully, there is a way to use the information that is already there :)

Any suggestions? :)
