Everything was fine until the firmware update .The update continues to fail . I have uninstalled the phone app and reinstalled it .I have tried unpairing the phone and monitor as well as unplugging the cord from the back of the monitor for 5 minutes . The update fail is describedas D26 communication lost .Product might be unusable. Any suggestions ? Thanks
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.
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: https://photos.app.goo.gl/9BJSLhVN2tJe5Yvk6
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?
My BMV monitor goes from 100% to 0% in a few minutes. I already restore to default settings, then it goes back to 100%, and again it goes back to 0%.
Someone can help?
Is there any way to clear/reset the history for SmartBMV?
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?
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.
Please can you help me figure out what the correct values for the;
should be on my BMV 700.
The BMV is monitoring 3 victron Gel BAT412101104 in the setup outlined below.
Any help would be very much appreciated.
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?
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) ?
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:
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.
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 ve.direct 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.
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.
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.
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.
Just wondering if I should get the Victron bmv712 to access my state of charge or is it possible to connect my Pylontech batteries to my Cerbo GX and it’s gives the exact same information? If it’s possible to measure Soc without BMV712. Would it be more accurate with the BMV712?
I have a VE.Direct LoRaWan within TTN coverage (blinking green) connected to a BMV-702 but no data seems to appear on VRM portal.
I've waited 2 days now and still nothing since "Last connection" (when I installed it and added the device on VRM portal).
Last power up or restart and last connection show the same time, 2021-09-25 14:57. No serial number is listed under the device information.
I saw someone with a similar problem on the community and something on the backend had to be corrected? Message/email me and I can share the VRM portal ID, the installation ID is 129941.
I am making some tests using a small off-grid solar system equipped with batteries and the following Vitron's products:
-BlueSolar charge controller MPPT100 30
-BMV Battery Monitor
Venus GX power consumption is supposed to be 12V 210mA.
How do you think power consumption would be reduced if I disable the Wifi Access Point?
Do you see other option what I could change to reduce power consumption, even by a few mA?
has anybody used the BMV-712 as DC counter in the Victronn Connect App via Misc. ?
There are two options to - the "normal one", using the BMV 712 as Battery monitor and a second option as DC counter. I have a client with a boat and an silent wind turbine with OEM regulator and two Victron MPPT BT controllers. The boat owner wants to see the input amperage of the Wind turbine.
I would be happy to get more informations about this function in the Victron Connect app and remarks on the wiring, if someone has it done yet.
Best regards, Ole
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.

One off my BMV-712 must have seen too much humidity and some corrosion is present in the socket pins. So much so that some pins are missing and it made the fuse blow. I am out of warranty of course.
Has anyone ever serviced that socket, yet alone gained access/open the BMV in the first place?
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!
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.
is the BMV 712 Smart Compatible with MPPT 150/35 controller?
Also interested also in knowing if the cables that are supplied with the 712 will connect to the controller.. Thanks in advance.
I have tried several times to reset the PIN on my BMV-712-Smart unit. It will not let me reset the PIN and now does not recognize the PIN that I had. It keeps giving me an error and returning to the enter PIN screen. I have tried both the new one and the old one and neither work. Is there a way to reset it back to factory default?
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?
Die Victron Battery Monitor BMV-600S Anzeige blinkt sporadisch nur kurz blau auf. So kurz das keine Anzeigewerte erkennbar sind. Was könnte defekt sein?
Alles hatte mal funktioniert und es wurde nichts geändert.
Geprüft habe ich:
- alle verbindungen am Messhunt und es liegen 12 V der Batterie an
- das Kabel (mit Typ Telefonstecker) ist korrekt am Display angesteckt, die 12V sind auch am Stecker messbar
Danke für Hinweise & Tipps!
Just installed a new lithium battery and the BMV-712. Been watching some videos on configuring the 712. Most mention setting the Low Voltage Relay. I have one lithium battery. Only have a victron 100/50 solar charger. That's it. Nothing else. Is a relay applicable in my set up? At a very basic level, when would one use a relay? Is it supposed to be used to trigger something in another device? Not sure how it would tell my solar charger to turn off. Thanks!
I have a smart solar mppt 100/20 on my panels , I’m about to add a BMV712
The system has a tail current of about 5 amps , ( the fridge on the boat ). If I add a bmv712 can the smart solar using VE.smart Bluetooth networking use the Bmv for to correct for this tail current as at the moment the solar gets confused and doesn’t end absorption mode.
Is there any special setup ? for this
