Smart Battery Sense data in VRM through MPPT75/10


My setup is Smart Battery Sense with bluetooth connection to MPPT 75/10, which has a VE.Direct USB cable to Raspberry Pi.

The MPPT can see the data from the smart battery sense, and in VRM I can see the MPPT. But I cant see the data from the Smart Battery Sense. Is this normal? I expected that the MPPT would pass on ALL data to the VRM portal.

Maximum input voltage for Smart Battery Sense

The datasheet says the Smart Battery Sense (I have the blue one) is compatible with 48V battery banks. A "48V" LiFePo4 bank can be as high as 58V. Is this OK? I ask because some time ago I hooked one up and it never worked so I'm wondering if I fried it with too high of a voltage. I have a new one and don't want to kill it also.

Help... 3 PV arrays, 3 MPPT and 2 battery banks

Hi - I have 3 separate solar arrays, each feeding into its own 75/15 MPPT which then feeds 2 separate battery banks (which can be individually selected or linked with a selector switch)

I guess my question is should/could all this be run on a single VE network? (I have 2 shunts, 2 BMS, 2 smart protect, 2 battery sense and 2 LiFePo 100Ah batteries)

My other question is if I link the batteries in parallel, which battery should I put the smart battery sense on? or shich should I connect to the BMS or use both?

Many thanks for all your help

Do I need a BMV to use the Smart Battery Sense?

I am waiting for better weather to install my solar charger etc to my campervan so I was looking at the demo mode of the victron app on my phone.

I have a smart solar 100/30 and phoenix ip43 12/30 and in demo mode there are warnings in the low temperature shut off (because I have a lifepo4 battery). Am I reading this right that the battery sense is basically pointless without a BMV?

Is this to force people to buy the BMV for ... reasons?

Smart Battery Sense + MPPT 75/15 stop charging at low temp?

Just installed a lithium battery in my camper. Can my MPPT 75/15 be programmed to stop charging below freezing? Yes, I know lithium BMS should stop charging from happening , but I found out after buying this one it doesn't. Not in freezing weather that much, so it's probably not a big deal. I'll just shut off the solar until it warms up.

2nd Question: Will I be able to see the sensor temperature via Victron Connect?

How to connect Victron Smart Battery Sense on Pylontechs?

Hi all

I am currently contemplating of adding a 2nd Victron MPPT to my system. As I am not using a GX in my system (using Axperts as inverters), I am looking to use a Smart Battery Sense to create a VE.Smart Network to synchronise the charging of the 2 MPPTs.

But I now have 2 practical questions, which I hope someone might be able to help with:

  1. I understand that the Smart Battery Sense is supposed to be connected directly to the battery's terminals. But how do I best do that for Pylons - given their non-standard terminals? Or do I connect the Smart Battery Sense to the end of the Pylon connection cable (where it connects to my DC busbar)?
  2. I am currently having 4x Pylons connected via a single Pylon connection cable (120A). As with the 2nd MPPT I might in theory be producing up to 135A, I thought it would be safer to add another Pylon connection cable (even though I don't think that the full 135A would ever be pushed into the Pylons as my load also still needs to be supplied). How would I connect the Smart Battery Sense when using 2 sets of Pylon connection cables?

Thanks in advance for inputs

Battery voltage greater than set voltage on Phoenix IP43 charger plus it now communicates with the BatterySense!

I have a Phoenix !P43 50/3 charger that after the last couple of firmware updates seems to have a higher output voltage than is set for Absorption/Float by 0.10-0.15v. Eg Absorption set to 14.60v on the app....actual battery voltage is 14.74v. Float voltage set to 13.05..actual voltage 13.20v.

This is measured both with the BatterySense and my calibrated Fluke multimeter...both readings are identical which is pretty impressive for the BatterySense I thought!

Whilst its easy to lower the voltage setting to get the correct battery setting I was wondering if any one else had noticed this?

Also thanks to the latest firmware update the Charger works with the BatterySense module which also means it compensates for any voltage drop between the charger and the battery bank which is useful when shunts etc are in the line. It does seem you can only have one BatterySense on the network though so can only monitor one out of the three possible banks that you could connect to the charger.

Look forward to hearing from anyone about this!

Control maximal Charge Current from SmartSolar MPPT 150/85 with BMV 712

Dear Victron,

I have installed an oversize PV System in relation to the battery in my car (Old VW T2), which I use to demonstrate PV opportunities in Indonesian rural areas. ( All installation is private financed by us and we try to promote renewable energy to rural places in Indonesia without any payback. But step by step the local media ask us for interviews and talks in the television and we start our blog in Indonesian on YouTube :D

1. The Panels can produce 1,16 kWp under STC. Size was chosen based on the maximal allowed space on the roof.

2. SmartSolar MPPT 150/85 charge my battery with an additional SmartBatterySense and BatteryProtect BP-100.

3. Just one Luminious SMF 12V 200h is installed due to weight and lack of space (I know this is not ideal, but it is an old car and 69 kg for each battery is just really heavy)

4. SUOER FPC D1000A Pure Sinus Wave Inverter (1000W continuous power/2000W peak power)

To increase the maximal life-cycle of the battery under tropical high temperature I reduce the maximal charge current to C10, which means 20A. When I demonstrate it to the people I put some big load to my Pure Sinus Wave Inverter. Since my PV System can easily produce more than 80 A on the 12V site at daylight, I need a device which can change the maximal charge current depends from the load.

The BMV 712 can easily read the current and direction of the current which going in and out of the battery and it can be easily connected via Bluetooth to the other devices.

Is there a possibility to drive the MPPT from the SmartSolar MPPT 150/85 with the measured current from BMV 712 so that the net current to the battery is limited to 20 A?

Or is there another device which can do this which is available in Indonesia, because Victron parts I bring directly from Germany? I didn't buy the BMV on those time due to lack of money, but now because of the response and the interest I need a solution.

It is so great to see the people step by step understanding renewable energy and with my background as a physicist i can explain them a lot :D

I am really happy for any advices or helps.

Thank very much.

Best regards,

How to wire my Cerbo GX to the rest of my Victron components

Hello all,

I'm a bit confused with how to wire my Cerbo GX to the rest of my components in the most optimal way. I'd like to be able to view the status of my system on a mobile device via bluetooth and also view the Cerbo GX web application from that same mobile device.

I have the following components:

- Victron SmartShunt

- Victron 12/3000 MultiPlus

- Victron SmartSolar MPPT Charge Controller

- Victron Orion Tr Smart DC/DC charger

- 1 VE.Direct Cable

The obvious connections to me are:

* MultiPlus -> RJ45 -> Cerbo GX

* SmartShunt -> VE.Direct Cable -> Cerbo GX

* SmartSolar Charge Controller -> VE.Direct Cable -> CerboGX

Here are a few questions:

1. Do I still need a VE.Direct Cable for the SmartShunt and SmartSolar Charge controller since they're bluetooth? Or is the bluetooth only so I can see them within the VictronConnect app via bluetooth?

2. Is it possible to monitor the Orion Tr DC/DC in the Cerbo GX?

3. What are the main differences between what you can view from the Cerbo GX versus what you can view within the Victron Connect app?

Temperature compensation and output of remote monitoring.

Having trouble interpreting the output of VictronConnect


  • Smart SCC 150/100
  • Smart Battery Sense networked with SCC
  • Quattro 5K/48
  • Color Control GX
  • 48V Trojan battery bank, 58.8V absorption

Remote monitoring via VRM, VictronConnect on PC.

Trojan says -5mV/°C/cell

24 cells

24*5 = -120mV/°C

I can directly see the Smart Sense when local and able to access it on bluetooth. I do not see that I have a way to access it directly via VRM.

I entered -120mV/°C in temperature while it was at the uncompensated absorption level. Voltage immediately increased about 1V as expected based on 34°C, and it didn't seem to be adjusting current to lower it. Shocked me a bit, so I flipped the sign and immediately saw a lower voltage. Head melted, and I just turned it off.


  1. Does temperature compensation adjust the measured voltage and make it read higher for °C above 25°C?
  2. If #1 yes, had I been patient and given the SCC more time, would I have seen the current reduce and the voltage settle to the absorption voltage?
  3. When I connect to the SCC, is the temperature reported in the app/PC VictronConnect (PC version shown below) from the networked smart sense or the SCC internal temp?
  4. If not the smart sense, is there a way I can see the smart sense via VRM?

SmartSolar not receiving data from BatterySense

My SmartSolar, BatterySense and BMV700 all show up correctly configured in the VE network.

In 'settings/VE Smart networking' the BMV and BSense both show up in each others app.
The SmartSolar only lists itself. In other words the other two are transmitting data, but the SmartSolar is not receiving it.

I have tried all the usual fixes. Deleting and restoring the network, trying different combinations of configuration. Nothing works.

I really need to get this working as the batteries are at a significant ambient temperature difference compared to the Mppt.

I have searched exhaustively for info on this with no success, which I find strange, I can't be the only one with this issue surely.

Smart Battery Sense - Blue Led , Static connected vs flashing disconnected

sorry if this question has been posted before but I’m new to the forum and couldn’t find any info on this.

The extract below is from a table in the smart sensor guide.

My understanding is when the blue led is slow blinking, it is still broadcasting temperature and voltage data. In the same way it is broadcasting if the light is solid.

My LED blue light is only solid when connected via my phone, When my phone is not connected the blue light blinks slowly as above.

My questions are:

1) Should the blue light be solid all the time when the sensor is connected to the VE Smart Network?

2) should the sensor be connected all the time ?

3) how often is data sent from the sensor - continuously, periodically or when changes occur

How to monitor the starter battery with my BMV-712? Wiring seems very complicated for my installation.

0 CB_Midkiff asked · Dec 10 at 4:27 PM

I have a housebank, which is charged by a Smart Solar MMPT 100/50 and connected and supervised by a BMV-712 via shunt. In addition I have a starter battery which is not connected at all to this house system. However I would like to monitor the starter battery also via the auxiliary input of the BMV-712.

Fig. 3 of the BMV-712 wiring diagram


Issue is now that the starter battery is about 5m away from the housebank and a cable connection for high loads would be quite complicated. From the BMV-712 manual I did see that normally I would have to connect the minus of the starter battery also to the shunt via a very thick load cable and an additional thin plus cable to the B2 port of the shunt.

Is there an easier way to connect and monitor the the starter battery via BMV-712?

Would it be possible to use the Smart Battery Sense device and connect it via bluetooth with the BMV-712 as an auxiliary input for monitoring the starter battery?

MPPT not receiving data from BatterySense

I have 2 x 100/30 MPPT and 1 x 75/15 MPPT all receiving data from a Battery Sense. Individually they all say they are happy and at night they all agree but when they start producing current the 75/15 starts under reporting by around 50mV compared to the others suggesting that it's not taking it's data from the Battery Sense. Consequently it is always the last to enter float

Edit - just to add to this . I have now turned off the VE Smart and the battery voltage is actually closer to the other controllers and the battery sense. So something is definitely not right with it.
