I have an install where a customer wanted to charge their RV LiFePO4 batteries via solar panels mounted on their shed and also use the RV power for running fridges in the shed, but they did not want the solar regulator mounted in the RV. A SmartSolar MPPT 100/50 was mounted on the shed wall with a 10mm2 x 5m cable length (10m return) between the solar regulator and the batteries. I knew voltage drop under load was going to be an issue, so planned on using VE Smart Networking to resolve the issue.
The customer already had a BMV700 installed in their RV, so I added a Smart Dongle to provide the BT connectivity to the Smart Solar MPPT100/50, created the VE.Smart Network on the BMV700 and connected the 100/50 to the same network, and the displays on both devices verified the voltage and current were being used (apparently).
The absorption voltage was set to 14.2V and float to 13.5V.
The displayed battery voltage on the MPPT 100/50 was showing 14.21V almost immediately on switching on the charging, the displayed voltage on the BMV700 was 13.5V (13.88V on the captured image, but that still shows it as different). The 100/50 immediately went to absorption, ignoring the BMV voltage. I would have expected the MPPT to display the BMV voltage and stay in bulk until the absorption voltage was reached.
SmartSolar MPPT 100/50: v1.53 (latest) at the time (Oct 31 2020)
BMV: v3.10 - also latest at the time
I have included screen images to verify my testing and configuration.
There appears to be a bug in the software, if someone can have a look at this, please?
I have 2 SmartSolar 100/50s and a SmartShunt running in a VE-Smart network. All are running current firmware and software. The Total Network Power in Victron Connect is only showing the power from one of the 100/50s. If I remove everything from the network and shut down everything and re-start, then re-add everything to the networks it works, but only for a day or 2. Anyone know how to fix this?
Is it possible to see the ve.smart data in VRM or in the GX device? I just bought 2 smart battery sensors to monitor remotely 2 batteries that are about 5 meters from my Cerbo and it would be great if I can check them online. As they are not part of the system, I don’t want to fit BMV or Smart Shunt, just check the voltage.
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
I want to run one charge profile for my Lithium batteries, controlled by both voltage and current fall off.
a) Networking it all together
b) Having a charge profile
Victron seems schitzophenic with their communications protocols. VeDirect, VENet, VEBus, VECan, VE Smart, USB
6 methods. Wow.
So lets assume you have solar with shading. So you want to have one MPPT per panel, to maximise output. That means lots of small controllers. And you want to connect to CerboGX for control.
How would you connect 8 x Smartsolar MPPT in a smaller size to CerboGX?
And once / if you did, you then also need to connect BMV-712 for battery current sense
And also Multiplus II as that charge profile also needs controlling.
The docs for VE.Smart (BT) indicate that the MPPT's will work together, but they are overridden by VE.CAN. Which is not supported by small units.
CerboGX does have BT, but does not support VE.Smart
You can connect VE.Direct to CerboGX via USB adapter, but no info on max qty, or if this will allow control of charge profile
And no discussion in CerboGX of Li charge profile control over Multiplus. Though us hinted in VE.Can info - but Multiplus(ii) doesn't support VE.CAN
Victron - how to make sense of centralised charge profiles for lithium? (Assuming batteries are not VE.Can Victron)
Or - even if they where.
[image]hallo, ich habe mehrere regler im netzwerk mit u.a. zwei mppt 100/20.
einer davon empfängt die stromstärke nicht über das netzwerk. was kann ich tun?
danke für eure tipps!
I am rebuilding the charging system on my boat (700 Ah Firefly battery bank). I have two 150/70 VE.Can MPPTs and a smart shunt on the ground return. The MPPTs are VE.Can cabled to a cerbo GX and the smart shunt is connected to the cerbo via a VE.direct line. The 1200 W solar can deliver up to 100 amps at peak into the batteries. A few questions:
1) is the network between the MPPTs and shunt done over Bluetooth or does the cerbo broker the conversation using the VE.can and VE.direct feeds? I much prefer hard wired connections
2) depending on (1), I may need to downgrade from a smart shunt to a shunt that has analog sense outputs that can be used by my new wakespeed 500 alternator regulators, as they don’t yet have support from Victron to get the VE.can data from the cerbo (per wakespeed rep). I love my smart shunt but without analog sense wires I’d either have to put another shunt in series or just swap out the smart shunt for an older one with both VE.direct and analog out.
Hi, I am trying to design a system for a catamaran,
have the following doubts:
1- 9xMPPT shall be connected via Ve-Direct/USB through USB Hub to Cerbo GX? or can they interconnect in Bluetooth? or just one via ve-direct and the rest within same BT?
2- Shall a smart sense be installed on the LifePo4 Batteries? on engines and generators batteries?
3- on the batteries connected to the phoenix charger, shall i install battery sense?
4- Ve-direct to Phoenix Inverter will make display its data?
5- Lynx 1000 and lynx distribution for quattro or Smart Shunt 1500?
6- smart battery protect 220, can i install 3 in parallel to have a limit of 660?
7- can i install a battery protect between busbar and main switch of each quattro to connect on/off in case of fire, cause the main switch will be difficult to reach?
8- remote panel is need to be connected to BMS in order to control quattro to just charge?
Hi. Will you add VE.Smart Network support on the IP22 Blue Smart Charger?
I own a BMV-712 with temperature probe and a MPPT solar charger which works really fine with VE.Smart Networking, so i think it would be really helpful to deliver the right battery voltage and temperature via Smart-Network also to the charger for temperature compensation and so on...
Thank you very much!
Is there anyway of getting data from a VE.Smart network into a third party device?
I'm looking for:
- Panel and charge data from MPPT SmartSolar
- State of Charge and battery data from SmartShunt
- Current values from Smart BatteryProtect
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:
Thanks in advance for inputs
We recently installed a SmartShunt 500A to our existing SmartSolar MPPT 100/50 which is connected to a Raspberry Pi running the VRM Pi Operating System.
The MPPT to Pi broadcasting to the Online VRM is working great.
But when we try to link the newly installed SmartShunt to a VE.Smart Networking network created on the MPPT, the SmartShunt can see the VE network, we can join it (it say it is joined), but the SmartShunt (or any devices added/linked via the VE.Smart Networking) is not appearing in the list of devices.
Both the MPPT and the SmartShunt have the latest Firmware version and so does the VRM Pi.
In the list bellow, I can see the Battery Monitor (SmartShunt) because we tried to connect the VE USB cable to it directly. But then we can see the shunt, but not the MPPT, even if we create a VE.Smart Networking network on the Shunt and join the MPPT to the Shunt network.
LOCALY, BOTH the MPPT and the SmartShunt are collecting data.
As you can see, the MPPT is showing just fine in the Console DEVICE LIST screen, but the SmartShunt 500A is "Not Connected".
I don't get it.
I have a MPPT 75/10 and a bluetooth smart dongle connected. Bluetooth connection works fine. Can i or can I not, connect this so I can be able to check status via local network. I have managed to create a network and the controller shows up, but i can't access this remotely in any way and if so, how.
If anyone knows? Merry X-mas
I would like to add a second MPPT to my Venus GX/Multi setup.
The GX has a limited number of VE ports, with the existing MPPT using the last port.
Can I use smart networking to sync the MPPTs over bluetooth?
or do I need to use a USB dongle to cable the new MPPT to the GX/multi?
I have used the Victron automotive wiring example for my 12V Sprinter build. Everything works fine, but I was wondering about one thing. To disconnect the MPPT charges a Smart Battery Protect 100 is used:
Now, if the BMS recognized f.e. high cell voltage it uses the remote control of the BP and no current is going to the lithium batteries. So far, so good. Instead of the "normal" shunt in combination with the BMV used in the schematics I use a Smart Shunt only. The Smart Shunt shares the cell voltage with the MPPT via VE.Smart network.
Now I have recognized the following. Everytime when the BP disconnects the current from the battery the MPPT shows a battery voltage of 14.2V even if the Smart Shunt battery voltage is only 14.0V (which is correct and verified via bluetooth connection to the smart lithium batteries).
Is this normal behaviour or am I doing something wrong?
The Smart Battery Protect is set to mode C (Lithium-Ion). The MPPT is using the Lithium Ion preset with a absorption voltage of 14.2V and float of 13.5V.
Thansk in advance
Hi, i have a 24/3000 Easysolar that has a CCGX (wich comes equiped with a 150/70 charge controller), and i also have a smart 100/20 solar charge controller, and a smart shunt.
My question is, how do i connect all this devices together so that i have all the information on the GX Color Control?
The 150/70 CC is already connected to the CCGX with a VE.direct cable, and that leaves me only one VE.direct input into the CCGX, but i want to connect both the 100/20 SCC and the smart shunt to the CCGX.
Is it possible to connect all this devices to the CCGX using only VE. smart networking?
Thanks alot for your answers.
System: I have 3 SmartSolar MPPT 100/30's connected individually to (3) 335W panels. They are networked together with a BMV-712 and connected to an 800ah LFP battery, with smartsolar battery setting on LFP. I just switched my battery bank to lithium from AGM, but I had the same issue with the AGMs. In the past, my shore charger was mostly charging the bank, but now I need to switch to solar and Multiplus as I will be leaving the dock soon.
Problem: Only one of the chargers is producing significant wattage (264W currently), and it seems to be charging the battery, although network total power shows 0. The other 2 chargers flicker some wattage and then back off to 0. It seems like the master controller is telling the slave controllers to not charge. In the smartsolar history, one can see that the all the chargers are working as they each have history on some past days of significant charging. I need all of the chargers to work together to charge the lithiums which are currently at 13.18v. Another anomaly is that 1 hour ago I was showing total network power of 255W. I removed each controller and the BMV from the VE network to try to reset it and then rejoined them all, BMV first. Now, total network power shows 0W, but the BMV shows positive wattage (175W) going into the batteries. Mostly, I need the chargers to all work together, instead of just 1 at a time, to bulk up the lithiums during the day. It seems like synching between controllers and the app may have glitches that prevent synchronized charging and also an issue with showing total network power.
On a sunny day this system should be pushing 900W plus into the batteries. Any suggestions?
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.
I was installing one of my Smart Solar MPPT VE.Can devices today, and browsing the menus to see what was around. Having never used or looked at VE,Smart I opened the menu and selected join existing and found an unknown network, "Olaso UNO".
The only thing in my Yacht that has this name is the Cerbo GX and VRM Portal. Any ideas what this is?
I've just setup my LoRaWAN device to transmit the data from my Camper installation.
I've even installed a LoRaWAN gateway at home and added it to The Things Network.
I'm sharing Temperature and solar data on the internal VE.Smart network, (see attached pictures).
I've connected the LoRaWAN module to the BVM-712 and I can see 'some' data on my Dashboard.
However, I can only see basic battery information. No starter battery, (even though this is reported in the BVM-712), no battery temperature and no solar information is available on the dashboard.
I [perhaps] wrongly assumed that as the internal network allowed the Victron equipment to share data, this would also be shared by the BVM-712 to the LoRaWAN module??
Am I [hopefully] missing some setup parameters?
Pretty sure this was asked a few years ago but wondering if anything has changed...
Any chance of VE.Smart Network coming available to the Blue Smart IP67 chargers?
Could really use that actual Battery Temperature reading...on these cool sunny days right now the ambient temp of the charger outside in the shade and the temp of the battery in a black plastic box is quite a big spread after a big charge (88f vs 61f - I think..the Blue Smart doesn't actually show temp- Another feature request to display Blue Smart temp?)
This leaves the MPPT on the VE.Smart Network to think that we are overcharging because it has temp compensated the voltage down for the warm battery (its probably right) while the BlueSmart IP67 is doing the opposite and temp compensating up for the cool charger.
I have seen others have asked this question for a long time!
What is happening Victron designers? This appears to be a very big omission from your system thinking!!!
All the other components in my system can talk to each other with VE.smart but not the mains charger. :(
Can you please provide an update.
I've got an SmartSolar MPPT 100/30 and SmartShunt. They are both connected on the same smart network. I was hoping that I would be able to source all the data from both out of the same VE.Direct connection. It doesn't look like this is the case.
Does anybody have a way to combine VE.Direct text streams? It needs to be RS232, my controller won't support TTL.
Otherwise, is there anyway of hooking into a VE.Smart network to get all the data from connected devices?
Is there anyway to link the Smart BatteryProtect into a VE.Smart Network?
I was hoping to be able to trigger it from the SmartShunt at a specific state of charge.
I’ve installed a smartsolar 75-15 and a smart battery sense. The temperature is shared correctly but the battery voltage is not correct. This setup is now expanded with a smart shunt as not all equipment is connected on the load output of the smartsolar (loads exceeding 15 amp) so the larger consumers were connected to a second fusebox which was directly connected to the battery.
To y understanding, the battery load from the shunt is also shared on the smart network but the smartsolar doesnt show this.
Is this a known issue or am i doing something worng?
All are purchased in the last 18 months and are updated. All 3 devices are connected the same ve smart network.
Ideas are more then welcome.
I'm using a Victron SmartSolar MPPT 75/15 to charge batteries and supply power to a load.
The system has isolator switches for both battery and solar, however we have found that occasionally the operator will disconnect the battery before solar, OR the battery fuse will blow if there is some system failure.
This cause the voltage across the load ports to spike to full solar input voltage before regulating down. The LVD is too slow to catch this. This has caused damage to some sensitive components attached to the MPPT load.
I want to use VE.Direct to monitor solar charge, battery state, and load power usage. But the load ports are proving to be risky. Is there a solution where we still get all the benefits of the load port in terms of usage statistics, but mitigate the risk of destroying attached devices?
My original thought was to use the Victron SmartSolar MPPT 75/15 paired with the Smart Battery Protect.. But I loose Voltage and Current stats for the load.
If I use the BMV712 with shunt, and run the load direct off the battery, will the MPPT and BMV712 communicate? What about the floating ground from the shunt..
Ideally is there someway to balance out the voltage spike from the load if the battery is disconnected?
How can I connect a color control to a smart shunt wirelessly? I want to avoid running a cable between the two. Is it possible to have the CCGX access units on a VE.Smart network by connecting to a participating smart-device via a VE.Direct cable, i.e using a smart device as a gateway to a VE.Smart network?
If I have the Cerbo GX plugged into my BMV-712, MPPT 250/100 charge controller, and MultiPlus 24/3000/70. Do I still want to run VE. Smart Networking between the BMV-712 & Solar Charge Controller?
I could not find a callout for the Cerbo GX. In some manuals, it states ' if you have an GX device that isn't just logging, such as Venus GX etc, disable VE. Smart Networking, Due to possible conflict'
1. Does Cerbo GX interconnect devices and passes telemetry superseding the need for the bluetooth PAN/ VE. Smart Networking ?
2. If #1 is Yes, do I disable VE. Smart Networking due to telemetry conflict?
I´m planning to install an ESS with the components listed above.
Has anybody realized this configuration already and may support me or has an overview/schematic?
