I had been using the Victron Smart shunt for over 8 months, and have been very very happy with it. I used the VE direct connection to communicate with the rest of the system (MPPTS, Cerbo & Multiplus), and it has worked flawlessly. I recently switched to a Lynx shunt (3 weeks ago), and quite frankly, was very disappointed in its lack of features, considering its a fairly new product.
With the Smart Shunt, I was using it to measure the top and mid point voltages of my 2s3p (24v/300A) system.
It also had a nice feature that you could reset and correct the SOC, should you have to shut the power off. (Both shunts loose SOC when disconnected from power). The Lynx CANNOT be reset to the last SOC, it only allows a 100% SOC reset, which is pretty useless.
The Lynx shunt DOES NOT monitor midpoint voltages or deviations, which is a feature I miss to be able to track if the batteries are becoming imbalanced.
Now, I do not know this for sure, but since using the Lynx Shunt I have had 3 occasions in the last week where the power from the Multiplus shut off due to one of the batteries dropping in voltage too low, under 12.5v. This never happened with the SmartShunt, and I am wondering if the Smart Shunt communicated the mid point deviations to the system, and it compensated in keeping the batteries charged and balanced?
2 hours ago, I reinstalled the SmartShunt to see if it indeed works with the rest of the Victron environment to do a better job of battery charging and maintenance.
Q. Are the features from the Smart Shunt going to be made available in the Lynx Shunt via a firmware upgrade anytime in the future
I'm building a new setup for a 24V system with Multiplus II for solar and wind. The battery system is flooded lead acid and I'm interested in monitoring the battery level and charge rate with a Cerbo GX. My question is about the following busbar setup I'm currently planning:
Left side: Lynx Power-In (4 IO slots)
1/ 24V battery system
Right side: Lynx Distributor (4 fused IO slots)
1/ Multiplus II 24V 3000VA
2/ Solar charge controller
3/ Wind charge controller
4/ Victron non-isolated DC-DC converter 24V->12V
It would be elegant to add a Lynx Shunt V.E. Can in the middle, but it would be quite expensive and the CNN-type fuse is crazy expensive. So my idea is to add a 500A SmartShunt between between lower negative bus and then a wire/plate between the upper positive bus. (On a side note, if the Distributor had 5 slots, I could only use that and put the shunt on the negative battery cable.)
Is there anything wrong with this setup for the intended purpose? Do I still need a separate fuse for the battery side?
Hoping I can get some help here, I am installing 2 new Multiplus-II in parallel system and all seems to be working well except i get all LED lights as red on the lynx distributor when I have AC power on and the inverters are charging. I have tested all the new fuses just via continuity test and the batteries are getting charged.
The even stranger thing is this: When I put the 120x2 3000 12v 50a Multiplus in standalone operation, they light will be green, then turn red after a period of time, then green again, but as soon as I put them in parallel and they are both charging the batteries from AC power, the led's on the lynx distributor stay red.... I have the battery protect connected to one slot on the lynx, 2 inverters (multiplus-II) each in its own slot, and the final slot is taken up by my BIM to chassis battery/alternator. The batteries are connected to the Lynx shunt via the end posts (where most people would connect the lynx power in). All the components have shutoff switches in between them.
Any help in understanding the Red LED's when under load would be greatly appreciated. As soon as I turn off the load the led's go off, and only the one green in the center of the distributor is lit. The lynx shunt stays green in any scenario.
Update - Even in standalone when the lynx distributor is under load the lights turn red. I have taken everything back apart and verified every connection but no matter what, under load, I get red lights on the lynx distributor. @Guy Stewart (Victron Community Manager) - Either load from chargers or load from the coach, ie when I turn on a microwave and a heater, it happens every time. I have ordered another lynx distributor to see if maybe it is a hardware board fault? I can't think of anything else it would be... Thanks for any advice in advance.
I have raised this with my retailer (CR for multiplus, and another company for the lynx) and they stated they would open a ticket with Victron, but have heard anything. I think this is an odd one, but maybe Victron staff have ran across this before?
The new Lynx Smart BMS seems like a nice addition to the lynx family, however when looking thru the manual I'm not able to confirm if its also possible to use the Lynx Smart BMS with non Victron lithium batteries?
What are the Amps -> mV values for the Lynx Shunt VE.Can 1000?
Hi, I have a 190ah LFP battery going in to an ammo can which will be in my truck bed. I'd like to heat the box using small ~25w heat strip(s) when the battery is too cold to charge, but only if it was going to charge in the first place.
What I mean by that, is that if it's the middle of the night and below freezing, don't bother because there's no sun to charge with anyway. Similarly, if I have a foot of snow on the panels and it's freezing outside, don't bother because the panels might not even produce enough voltage to initiate a charge cycle.
I was thinking some combination of the street light function, load ouput, and BMV low temperature relay setting could accomplish this. Likely easily with the ability to invert the streetlight functionality but I do not think that's possible from my research. Maybe some NC relay that the streetlight triggers when it'd normally be operating an actual streetlight (night?)
Any ideas appreciated!
I attempted to connect a 4/0 copper cable 5/16 hole lug from the Multiplus to the Distributor, but lug seems to be too large to fit into the opening for the negative bus bar on the Distributor. Can someone recommend a lug that will fit?
I am aware that a new Lynx Shunt VE.Can is initially set up to have the battery distribution to its left and the load distribution to its right. Is it possible to modify the Lynx Shunt to allow for the battery distribution to be on the right instead?
I am wondering if changing the position of all or some of the five sensing wires inside the unit would allow for changing the location of the battery distribution. If it is possible, which wires need to be moved and to which positions? If this is not possible by physically moving sensor connections, is there a software setting that could be changed?
My system is currently set up with the battery distribution on the right side of the Lynx Shunt. Based on my VRM portal reports the shunt is measuring the current flow in the opposite direction for how the system is connected. As an example, if my battery bank (9.6kW capacity) SOC drops from approximately 100% to 21% and my inputs are 1kWh from the grid and 21 kWh from the PV array, the VRM is reporting my consumption as 15kWh. Based on those input numbers (which I assume are collected directly from the Multiplus and MPPT), I think that the consumption number should be around 29kWh.
My system is:
8 x Battleborn 12V LiPO batteries (configured as a 24V 400Ah bank)
2 x Multiplus 24/3000/70
1 x SmartSolar MPPT 150/85
1 x Orion 24/12-70
2 x Lynx Distributor (used on battery and load sides)
1 x Lynx Shunt VE.Can
1 x Cerbo GX
1 x GX Touch 50
Trying to use the Lynx Distributor (and Power In) without the Lynx Ion Shunt or BMS (using BYD batteries). I had assumed the Fuse LEDs would illuminate with a working fuse in place and powered, however a line on the old Victron Live page for DC Distribution Systems suggests that this small data cable is used to power the LEDs (rather than taking power from the busbar itself). I cannot get the LEDs to illuminate - are the LEDs useless unless using the Lynx Shunt? Because Lynx Shunt uses CANbus, it cannot be used in conjunction with BYD on a CCGX (though I think VGX would support it).
Hi, I wonder if it is possible to use midi fuses on a lynx DC distribution system? So far I only can see the lynx only allows Mega fuses.
I have a Cerbo GX connected via VE.Can to a SmartSolar MPPT 150/70 VE.Can and a Lynx Shunt 1000 VE.Can. I have DVCC enabled as well as SCS, SVS, and STS. I have found that the MPPT changes charging states correctly according to the readings from the shunt. However, it is not compensating voltage according to the temperature reading from the shunt. The MPPT seems to be compensating from the initial ambient temperature as the standalone strategy. The MPPT has v3.05 firmware and the shunt has v1.08. Any help would be appreciated.
I am connecting 2x UP2500 24V Pylontech batteries in parallel for use with the Multi-Plus II 24V/3000VA and was wondering if I need Lynx shunt or Lynx power in to do this. Or is the Pylontech internal BMS capable of monitering all of this and communicating with the Cerbo GX.
Below is the details of the setup I will be running. Please feel free to point out anything else I may be missing with this setup. Thank you in advance!
-2x UP2500 PylonTech 24V batteries
-Victron Multi-Plus II 24V/3000VA
-Victron Smart Solar MPPT 150/100 Tr
-6x 370w Trina solar panels
-Victron Cerbo GX and Touch display
New setup with Lynx Power In, Lynx Shunt 1000 (VE.can) and Lynx Distributor connected to LiPo (24 V 200 AH). All Victron. Downstream are 2 x Battery Protect 220, VE.Bus BMS, Multi 24/5000 and a VenusGX. All 'smart' units have latest firmware.
With all loads off there are no lights (LED) on either the Shunt (1) or the Distributor (4)
I have read all of the related posts on this site and in particular the three (3) links that Guy provided to a closely related question.
Have checked all connections to the batteries and both input fuses as well as the shunt fuse. All are OK.
Q1. Any thoughts?
Hello from sunny south florida,
I an Electrician and my company assigned me that task of building out a camper van for a client. After some research I ended up using a multiplus 12/3000 with a CCGX, the lynx shunt 1000a, a 45amp mppt solar charger with ~250w worth of solar panels on top of the van(I wanted more panels but customer wanted more storage)and 2 renogy 170Ah lifepo4 batteries in parallel, and an alternator charger. The equipment seems to be operating as it should with the exception 1 thing that just popped up last night. The load on the system is roughly 20w to power the ccgx and the cellular internet (according to my CCGX).
with the rating of the batteries at 2175w each i estimated the system should run for ~200hrs +/-with no charge, ive been monitor the vehicle through VRM and it all has checked out until yesterday..the customer has had the van parked not in use all of last week. We had good weather all week with the exception of friday when it was cloudy all day and the solar didnt produce much.
To get to the point though the batteries died after ~ only 24-32hrs of no input am i mis-calculating something here or do i need to look into the current calibration of the system?
I have decided to use these for teh first time on my next big project. ( 3 x 10 Kva, 4 x 250/100mpp2, 2 x 20 kwh freedom won) What is the maximum fuse size, each invertor will need a 400 A and the same with the 2 batteries.
There seems to be an error in the consumption calculations and historical data in my VRM portal. An inconsistent amount of power, that based on my best guess, is unaccounted for power that has actually been consumed by the "DC Power" system and the overhead of running the inverters. I am not sure if this is due to an error in the VRM programming or in one of the equipment settings somewhere in my system (which is only a month old). My other concern is that the VRM is not taking into account both inverters in this split phase system.
I have a 24V 400Ah LiPO battery bank, which means I have roughly 9.6kWh of energy storage. I am using that as the basis for comparing what is and isn't being accounted for. I have read the VRM FAQ and understand that the "DC Power" that is reported in the live view is a calculated number based on the difference between what the inverters are using/generating, the MPPT is generating, and the amount of energy flowing across the shunt. There is no additional equipment wired between the battery bank and the shunt and I have confirmed with an ammeter that the live reporting of what is actively being consumed by the "DC Power" system and the inverters is accurate.
Here is an example of a 24 hour period in which the SOC is nearly the same at the beginning and end, but there is over 3kWh of produced power that isn't accounted for:
Here is the time during that same 24 hour period in which the batteries were not being charged by the SmartSolar MPPT, and almost 1kWh of consumption is unaccounted for based on the change in SOC:
Here is the time during the 24 hour period in which the SmartSolar MPPT was charging the batteries, and it seems that 1.8kWh of consumption is unaccounted for:
Here are the battery bank settings I currently have programmed in my Lynx Shunt per Battleborn's instructions:
My system equipment and firmware versions are as follows:
8 x Battleborn 12V LiPO batteries (configured as a 24V 400Ah bank)
2 x Victron Multiplus 24/3000/70 (Firmware: 481, VE.Bus version: 2712481)
1 x Victron SmartSolar MPPT 150/85 (Firmware: v3.04)
1 x Victron Orion 24/12-70
2 x Victron Lynx Distributor (used on both sides of shunt)
1 x Victron Lynx Shunt VE.Can (Firmware: v1.08)
1 x Victron Cerbo GX (Firmware: v2.63)
1 x Victron GX Touch 50
Since "DC Power" is not a measured number does that mean it is not reflected at all in the VRM historical data? Is the consumed power recorded in the VRM only the AC power supplied by the inverters? Is it possible to have the total DC power consumed by the entire system be the number recorded in the VRM portal as "Consumption?"
I would greatly appreciate some input from anyone who might be able to help. I know @Teun Lassche (Victron Energy Staff) has recently been answering questions about the VRM Portal.
Hello everyone. I have made a final setup that im going to install shortly. I would love to hear some advices about the setup, i am no expert so anything will help :)
-12x450Wp Trina solar
-Multiplus II 48/5000
-Smartsolar MPPT 250/100-Tr Ve.Can
-4x US2000B Pylontech
-GX Touch 50
-And maybe the Lynx Power In to be able to install MEGA Fuses.
What do you think of this system? Thank you in advance!
Hi, I'm installing pylontech batteries and ccgx color control.
Multiplus 2. 48/5000...
I have a lynx shunt, is that still worth installing and interfacing with the ccgx ? Will that clash with the pylontech bms?
Or just stick with the pyramid bms....
Thanks for any advice.... Dave...
@Guy Stewart (Victron Community Manager) I posted this to an existing reply but thought of posting this here as well.
We are using 20 units of LTO 48V batteries - 31.5A each connected in parallel to busbar = 630A
1. Can we use Lynx PowerIn instead of Lynx distributor if we added to Lynx PowerIn additional M8 bolts in those provided case mouldings with mega fuses?
2. I looked at the existing bolts and if we use the same size there is a height difference, so will this matter when installing the fuse?
3. We are linking up to 5 Lynx PowerIn so do we need to keep all batteries connected to one Lynx Powerin busbar with mega fuses or if we have space we could connect Quattro and Mppt to the same as well. OR do we keep batteries separated and just use a separate Lynx Powerin just for our quattros and mppt?
4. Lynx Powerin = 1000A.
so this mean that on each one max A = 1000
But if we are using 5 Lynx PowerIn connected together and use them for quattro/ mppt and battery connection then should the total of battery A be less than 1000A?
5. Or should we use Lynx Power Distributor for all battery side connections with Lynx Ion+shunt in between this and our Lynx PowerIn where quattro and Mppt are connected?
Appreciate your comments and Thanks in advance!
I am trying to find a datasheet of the Lynx Shunt VE.Can but am not able to.
More specifically I would like to know the resolution and accuracy of the current measurement.
I intend to use this together with some own developed components and interface through CAN, but will I need a CCGX, VGX to set up the Lynx shunt? Or is it possible to set it up through the CAN interface?
I am planning a setup to use a Lynx Distributor for batter input, then Lynx Shunt, and another Lynx Distributor to the loads. Management will be a Cerbo.
Question: In such a configuration what are people doing for emergency battery disconnect switching?
Just wondering how to swap the busbars from left to right. I've had a go but are worried about the electronic board as it doesn't seem to want to move
Greetings All. I'm just diving into this world and I'm having difficulting understanding the relationship between the BMV and the VenusGx. Specifically, If I'm using the Lynx Shunt to provide input to the VenusGX, does the BMV receive the battery data from the Venus via the VE.Direct link, without the need for a second shunt (the one that comes with the BMV)?
Or, is the BMV a transmit device only, which would make the Lynx Shunt input to the VenusGX redundant and unnecessary?
Thanks in advance for any insight you can provide.
Hi i have a set up that consist of this
2x smartsola mppt 150/100
Lynx shunt and lynx distributor
Old 800ah lead acid battery 48v (16pcs 12v 200ah)
Can someone help me? I will be replacing the lead acid batteries with pylontech, but for now i have to use the lead acid batteries while waiting for the pylontech. Cant seem to get accurate soc and sync batteries
running on ESS, battery monitor is lynx shunt
Anyone know the lynx shunt reference voltage? Would like to attach my BMV PCB board to it so I can still use it.
I’m considering wiring each of my 4 LIFPO batteries to the Lynx Distributor separately. I’m wondering if anyone with experience has thoughts on the following:
1) Do the wires to each battery need to each be the exact same length? I know it’s important in traditional parallel wiring for wire lengths to be equal, but haven’t seen anything on this when wiring directly to the Distributor.
2) Is battery balancing impacted with direct wiring as compared to traditional parallel wiring each of the batteries together with diagonal positive and negative terminals wired to the Lynx Distributor?
3) any thoughts on cost efficiencies of wiring each battery directly to the Lynx Distributor? Smaller wires, but more fuses, etc.
I've been running the BMV for a few years and have ~60 automatic sync. I also have been running the lynx shunt for a while with about 10 automatic syncs. I've confirmed the settings between the two and interestingly they are wildly off between them. I've tried a couple of things and have some examples below. I've set up a rPI + grafana/influxDB to capture data at higher resolution than VRM portal so I can look at the data in different ways.
The large vertical jumps on the Battery SOC is from me forcing the SOC to match the Lynx to see how the slopes match up. The interesting things here is that the Ah Consumed match up pretty close with the Lynx SOC but not even close on the BMV.
With the the value right now, you can see I've consumed about 86Ah of battery power (86/1200), or about 7% based on the BMV stat. This is almost perfect with the Lynx showing 92% SOC, but the BMV shows 84% SOC. I then forced the BMV to be 92% a few min ago to see if this lines up.
While the Lynx CANBUS updates are slower than the BMV, there might be a bug with the BMV?
Grafana screenshots and BMV + Lynx settings attached. Am I missing something here?
Im trying to find out the fuse needed for this schematic that I want to install in an off-grid
I would install 4 2.4kW Pylontech batteries.
The MPII manual suggests to install 200A fuse but I think it might be too much for this?
I have just published the Lynx DC distribution manual
I would appreciate any feedback, suggestions for how it could be made better or clearer, or any questions you have that it doesn't answer.
Quattro 15Kva-240V-48V- 4x4 (16 total) Victron 220 gel batteries 12V x 4 = 48V . 2 MPPT250/100
Triyng to find the best and nice looking solution to connect all 4 parallel string of batteries . Planning to use a negative and a positive bus bar receiving all 4 negative cables and all 4 positive ones.
Wondering if the Lynx power in can do the job : Receiving 4 of each lugs on the side connectors , and receiving the 2 MPPT and the Quattro + accessories (via the BMV712 Shunt) on the bottom connectors ?
Grateful for assistance
