BMV 712 is always showing 100% SOC and not recording any history other than charged energy?

My system consists of Victron Easyplus, Blue solar MPPT, CerboGX, Sterling B to B and BMV 712. Battery bank is a self build Lithium 280ah with Daly BMS. I have checked and double checked my wiring and settings and cant understand why the BMV is not operating as expected. There are no loads connected between the shunt and battery the BMS is on the load side of shunt. The BMV is permanent 100% SOC, does not show any AH Consumed and no discharged energy. The loads are the Easyplus in AES mode with a 240v fridge coming on for approx 3mins per hour with a load of 2.6a. The BMV seems in permanent charge condition with 18a & 250w even though there are no charge sources other the MPPT or Easyplus when on shore. So shows the same situation at night and without EHU hook up. Would appreciate help to sort this out it's driving me nuts.

BMV-712 suddenly displaying a wrong voltage of 0.02V

I had my BMV712 running for some weeks now. This weekend during dischcharge, the main battery low voltage alarm suddenly triggered. The main voltage was displayed as 0.02v.

Link to screenshot:

this was during normal operation of our camping car. whilst no change was done to anything...
i checked the "real" battery voltage using a DMO and it was 13.x volt.
i quickly inspected all the cabling, but all seemed correct. (and all other values including current from the shunt looked correct..
I then did a reset to factory settings and the voltage was back to normal display (but it started with 100% capacity..) .
It seems to me like a software problem as the only thing i did to resolve it was a factory reset...

Any ideas or suggestions? or is the unit defective?

BMV-712 weird readings and calculations ?

Bought a BMV-712 as an enhancement for my Smart 100/50. My intention is to get a better view on the SoC and remaining capacity of my solar batteries of my cabin. As the 100/50 is very far away in a remote location I prefer to test things prior to go there. So here is what I did.
I took an older 12V / 42A wet battery and connected the BMV-712 and shunt. Configured the 42Ah in the app. Then I charged the battery for 24 hours to be 100% sure it is @100% SoC, charger displayed "float". Then I set the Soc=100% in the app.
Next I connected two 12V/21W bulbs to discharge the battery.

I expected to see correct values for decreasing SoC and remaining battery time after a while.

However the values I see after a few minutes are:
9.87V @ 3A (battery seems to be pretty done), but instead of seeing a low SoC, the SoC still is at 94.6% ! I would expect almost zero when the battery is at 9.87V.
Am I wrong with my setup and expectations? Do I need to repeat some steps to allow the BMV to learn?

Falsche Einstellung vom Dashboard

Hallo liebes Victron Energy Forum.

Ich habe mir einen Victron Cerbo GX mit Stromzähler ET340 gekauft.
Dies habe ich zu meinem bestehenden SolarEdge Wechselrichter installiert.
Die Daten von Wechselrichter wurden gefunden und werden angezeigt.
Wie auf den Bildern zu erkennen wird in der Übersicht der Netzbezug mit minus gekennzeichnet wenn ich den Strom ins öffentliche Netz einspeise, was ja auch richtig ist.
Leider wird im Dashboard was ganz anderes angezeigt.

Dort taucht nur der Wechselstrom Eingang auf. Und wird mit N/A beschrieben

Ab und zu erscheint dort aber auch ein Symbol mit einem Generator.
Habe ich etwas falsch eingestellt?
Es wäre schön wenn ihr mir helfen könnten.

BMV-712 Smart: buttons disabled?

My 2 months old BMV-712 Smart does not respond to the hardware buttons on the display anymore. Following the latest firmware update it was initially working fine, but is now stuck showing usage / yield in Watts. The app on the other hand is still fully functional, so power, bluetooth and connection to the shunt can't be the issue. It's almost like the hardware buttons were disabled by command, but I haven't seen any option in the manual to do this. Is there a way to enable/disable the buttons?

How to connect SmartBatterySense to setup with BMV

Ive added a SmartMatterySense (SBS) to my system so I can monitor battery temperature when solar charging my lithium batteries.

The SBS instructions says to connect +ive and -ive wires to batter terminals, but how does this work when I have a BMV-700 with shunt attached to the -ive battery terminal?

common wisdom is all -ive lead should be connected to ground side of the shunt .

I appreciate the SBS only draws a very low current (20mA), however should I connect SBS -ive wire to the -ive battery terminal (as per instructions) or to the ground terminal of the BMV shunt (as per common wisdom) ?

Lithium battery monitor by BMV + GX

I have an off-grid system using Multi and Pylontech batteries and a Color Control GX. It is installed in another building outside the house. The user wants to monitor the SoC of the pylon inside the house. I was thinking about using a BMV but I have some doubts since the real SoC is on the CCGX from the BMS:

  • can I use a shunt for an independent SoC measurement? will this shunt affect in some way the BMS readings?
  • if no, can I connect the BMV to the CCGX and get the SoC data from the BMS and only read it at the BMV?

I have read in the ESS manual that using both SoC measurements can lead to a conflict, but they do not state why. So I am wondering if the conflict remains if I want the 2nd measurement only for display purposes instead of controlling as well.

By the way, there is no internet connection at the site, so monitoring through the VRM portal is not an option.

Peak Power Pack and SmartShunt: can I tie all grounds together?

I would like to track the state of charge of my Peak Power Pack, something which is sorely lacking (for the price I kind of expected something like this to be included, actually!). The difficulty is the different current paths, I have the charger connected, the car/solar connector is also connected, and of course the load is connected to the "mover" output. Can I tie all the "minus" connections together (charger, car/solar, load, and possibly even ground), connect this to a smartshunt, and then connect the smartshunt to the PPP? In other words: the minus of the charger adapter, the car and the load are connected to the load side of the shunt, and the other side of the shunt is connected to the mover output minus of the PPP.

New to the Solar Setup in our Trailer - Want to add Phoenix Inverter

We just bought a 2022 Intech Sol Horizon Rover Camper Trailer. We had our dealer install a solar package that Included 300 watts of panels to a SmartSolar 100/30 MPPT feeding dual 120Ah Lithium batteries (240ah Total) with Monitoring via the BMV-712. (See the picture below)


We haven't had it but a few days but I would like to add a Phoenix Inverter 12/1200 and connect it to our existing breakers by way of our Progressive Dynamics PD4135. I realize I need a transfer switch, either manual or automatic, and will need to turn off the converter manually in the PD4135 every time I want to run off the inverter.

  • Do I connect the inverter to the shunt of the BMV-712?
  • Should I look at the Filax 2 transfer switch? Why is it so pricey compared to other options? Is it worth staying in the Victron Brand?
  • Do I need to upgrade the gauge of my cables? They look puny compare to other installs I've scene.
  • Can someone help me gain a better understanding of what parts I will need to accomplish this? What size breakers, wire, etc?

BMV712 shows a difference in Voltage in Starter Battery and House Battery

Hello together,

This is my first post and i tried google, youtube, Insta etc for help. My 712 was working fine and it showed the correct numbers but suddently it shows the wrong Voltage. For the starter Battery it is 0,03 and for the House it is between 0.3 and 0.4 Volt. I tried to hard reset the monitor, plugged of the cable for 20 minutes. Also the Shunt Connection has the correct Voltage. So instead of 13.6 on the house it shows 13.3 and for the starter it i 12.71 instead of 12.74

we also checked the batteries, they are in a good condition.

I hope someone can help and it is just a minor Problem.

BMV 712 Bluetooth connection problem

For month the Victron app worked flawlessly with my BMV.

Now when I click on the BMV in the device list it doesn't connect and it says “Connection not possible, delete device from connected device list and reconnect (in German)“

So I deleted the BMV from the device list on my phone in the Bluetooth settings.

But nothing changed. In the app I can't do anything sensible, just changing code by typing the PUK.

Then I reinstalled the app from my phone. Nothing changed, the BMV is still in the list but won't connect.

Now I read the manual and searched here for an hour but didn't find a solution.

Please help me.

BMV-700 displays always "CONNECTING" and do no responds to reset command

Dear friends,
I had a system with four solar panels Victron Energy, two 75V/15A charge regulators and two BMV-700 monitors. All was perfectly functioning. Some days ago I have added other panels to my system and I have changed the two charge regulators with two 100V/30A, cause the increased power. Now the system is well functioning: panels, regulators (monitored throught the Bluetooth app), except the two BMV-700 monitors, displaying everytime "CONNECTING". I tryed to reset them to the factory defaults, but they do not respond.
It is important to restore them, because the Bluetooth app displays only the power in Watts and in Volts entering, but not more, while the BMV-700 shows many informations more.
What can I do?
Thank you for your kind answer and have my best regards.

Wiring diagram bmv712 and blue smart charger

Hello all,

I bought a new boat. In this boat we have an old charger and a analoge voltage meter. As a winter project I upgraded the charger and voltage meter to an Victron Blue Smart Charger IP22 12/20 (3) and a BMV-712.

As in most older boats the electrical system is a mess and I want to clean it up as much as possible.

I've got an household battery and a starter battery. My question for now is.... Is the wiring diagram which I made correct? Or is there still a problem.

In the current situation the negative lines of both the batteries are connected to the most left positioned switch. I understand this needs to be changed if I place the BMV712 in my boat.

Kind regards,

My Victron 712 Smart Battery Monitor has always worked perfectly. Now that I have upgraded to an Apple 13 Pro Max the Victron ap on my iPhone needs to be paired with the 712. The ap finds the Victron unit and begins connecting. At about 80% it asks for a paring code. Unfortunately the 712 does not display a paring code. Have tried powering off, resetting, etc. So far no corrective action found. Hopefully someone knows the fix!

Multiple BMV-712s in one system with multiple batteries

Hi everyone

I'm new here and have been trying to find some answers to a BMV-712 challenge. I'm building 4 large (51.2V 270Ah), separate batteries for my off-grid house. Each will then be wired in parallel to a Lynx Power In attached to a Lynx shunt.

I would like each battery to be a completely separate unit, so that I can disconnect and do maintenance on one without loosing power to the whole house. Each battery will have a separate BMS (BMS123 Smart) connected to a Contactor for disconnection in an emergency. In order to keep a separate eye on each battery's SOC, I would like to add a BMV-712 to each battery as well (with temperature monitoring).

I realise, that only one BMV can be available to show the SOC of the whole bank on a GX, so I'm fine using the Lynx Shunt for this.

1. Is there anyway of showing the other 4 BMVs (one per battery) on a main display, or will I have to use the small display on each BMV to check that the state of their individual battery SOCs, temp. et cetera?

The 712 Data sheet says:

“A maximum of four BMVs can be connected directly to a Color Control GX. Even more BMVs can be connected to a USB Hub for central monitoring”?

I have added a diagram, hope it makes sense. Any advice would be greatly appreciated.

Thanks, Marcus

Can I use a "Cerbo GX + GX Touch 50" instead of "Digital Multi Control 200 + BMV-700"

Hi, I am installing a new system with the core components being a Multiplus 12/3000 inverter/charger, 2 x LiFePO4 Smart Batteries (12V/200Ah) & a VE.Bus BMS. I have been recommended to include a "Digital Multi Control 200 + BMV-700", but I'm wondering if it would be better to replace those 2 items with a "Cerbo GX + GX Touch 50". I would like the ability to monitor/control things remotely, and I have read (in other posts here) that you cannot change any settings remotely (nor via the touch panel), that can be set via the physical switches on the DMC (which takes priority).

So my question is really, can you do everything via the Cerbo GX & Touch 50, thus doing away with the need for the DMC & BMV altogether?
