In this video, we are having a look at the Victron Smart Shunt and its settings and functions in all details. It's an underrated amazing device. Most people think they don't need one because they have a shunt built-in to their BMS. While this may be true in some cases, the Victron Smart Shunt has some very nice features and should be the point of truth in your solar battery system.

@djordjeblaga7815 Жыл бұрын

Just to add to the confusion: I have found, that in my system the JK BMS and the Lynx Shunt SOC values are actually identical. They weren't at first because I didn't top balance my cells, but after a few days of balancing with the JK they're now below 10mV difference and all charge to the 3.4V equally fast. So now the two SOC values perfectly match up :) I've got just one 280Ah battery with 10kWp solar, it goes down to around 50-60% overnight and is at 100% as soon as we get a few hours of sunlight :D

Yes, it's a bit confusing with all those settings though. One thing I have discovered is that I would like to see a setting called constant watt instead of constant current because (now it's coming) when you charge with constant current the voltage on the battery increases and then you charge with more and more watts example ( 2.45x100A=245w 3.45x100A=345w). You do an excellent job and also entertaining and educational, I love your solar panels on the roof East and West and then in the middle of a forest of trees.

I love your work - reminds of my younger days DIY'ing everything from slate/glass HiFi turntables to homemade Hibachi BBQ's. Nowadays I just buy a BBQ or a HIFi. Battery SOC on a DIY Solar PV Lithium battery system is a bit like range anxiety in an Electric Vehicle. We are progressing to a stage where battery Capacity and SOC are of academic interest. I am there right now. Knowing these figures in real time is an interesting nice to have right now. My Off-Grid (nearly) home runs for months without me looking at them. In the beginning, about 7 years ago, I watched them like a hawk, 24/7. IMHO, unless the Victron Smart Shunt is integrated into the system in some way that it actually controls something which results in a positive outcome, I would rather live with the figures presented to me by my Inverter and spend the cash on something nice.

@FutureSystem738 Жыл бұрын

Thanks Andy- great and topical as always. My smart shunt (actually BMV-712) is a lifesaver in my caravan. Without it, I would often have almost no idea how much capacity I had left. However many people DO still get caught after a lengthy period of time without doing a sync at top of charge. Over time it’s reading can become very unreliable without a sync. I’m guessing your’s would be a fair way out of whack if it hasn’t synced in forty something days. By the way… do you know when and how the JK BMS recalculates top of charge for it’s SOC reading?

If your solar charge controller allows for it go ahead and over panel it. Solar panels are fairly cheap in comparison to the rest of the system. It's worth overdoing!

Hi Andy. I'm from South africa and have 2 Freedom Won eTower 100Ah batteries which uses the Pace BMS. I recently returned one of the batteries because it had an issue with bad cells and Freedom Won replaced it with a new one. The issue I have now is thaat the old battery *bought Dec 2021" and the new battery have different firmware version. The old one at V1.10 and the new one at v5.07. This has been checked and updated to the latest firmware by Freedom Won. It does seem that there is some compatibility issues. When reaching the lower side of SOC% levels the SOC% of the 2 batteries differ up to 27%. The Victron equipment then seems to use the middlepoint. What this caused now is that when ESS starts to use grid power at set 20% SOC the new battery sits as low as 7% while the old battery sits at 34%. Freedom Won swears that the two firmware versions are 100% compatible. What do you think? I suspect it;s the Firmware causing the problems. Next I want to do capacity tests on each individual battery but after no sunshine for days, I'm waiting for some sun to fully charge the batteries before I can continue with the tests. I try to only charge them from the grid in emergencies. I would really love to hear your thoughts on this.

@lexicase8805 Жыл бұрын

I have the bmv712 and my biggest problem with it is the relay setting by state of charge, affects discharge floor and therefore also affects the time to go counter. For example i have the soc relay setting to turn on my hot water service above 80% soc, and turn off below 60%soc, therefore my time to go counter now doesn't work if my battery is below 60%. I have the hot water set like this because i know that i use roughly 40% of my battery capacity overnight during winter with electric blankets and such, and wanted some headroom for emergencies, so given that hot water is more a luxury than a necessity, having it cut off at 60% was a good idea. But as i said, this now means i have no time to go counter below 60%, and the time to go above 60% is only counting that top 40% of the capacity. Victron needs to separate the soc relay setting and discharge floor setting. Also, if i go and set up the soc relay to my desired percentage, and then go and adjust the discharge floor, it also automatically adjusts the soc relay to the same setting. Why bother having two settings in the menu if they both do the same thing?!?!?

@silverbullet8779 Жыл бұрын

Hi Andy, I have been waiting for this video for some time. I am having issues with the smart shunt resetting to 100% when fully charged. In my application the bank is charged to 100% on a daily basis if all goes well, but the smart shunt will stop at 97% and not reset at least half the time. On consecutive days ill lose another 3% even though the voltage reaches 14.2v. Right now i just reset the shunt to 100% if there is a problem. The settings at the moment are Charge Voltage - 13.9, Tail Current - 2%, Charge detection time - 1m

I have a Victron Smart Shunt and a single 16 cells bank (304 Ah per cell) with a Daly BMS (yes I know... and I blew it last week because I removed the wire on the last cell during wiring maintenance without disconnecting the 17 wire connector - $200 wasted - I will remember this one). The Daly reports always lower than the victron and at some point it was stuck in the 50-60% range while the victron was at 95% which made sense after a few days of full sun and many KWh of charge reported by my Growatt (via SolarAssitant). Which, by the way Andy, you should test as this is a nice app to monitor an all in one inverter like Growatt and it can also monitor my Daly BMS and supports many other even the JK one. Nice charts too. It runs off a Raspi 3 or 4.

@OffGridGarageAustralia Жыл бұрын

Thanks for sharing, Michael. A shame the DALY got destroyed when disconnecting the last wire. This is the power supply for the Daly (most positive) and should just turn it off. Yeah, I have a Raspi here already and need to pay around with the comms side of things. There is just not enough time 🤷‍♂️

@michelmarchand2291 Жыл бұрын

@@OffGridGarageAustralia Well this is my guess that I cause the Daly to fail. But it could also be the Raspi of SolarAssitant that connects to the Daly serial port that damaged it because the power supply section of the Raspi burned and smelled at about the same time and when I touched the serial connector the Daly shutdown. Daly is working but reports many errors related to its memory - it's useless and will not even read cell voltages. So maybe it's not me that killed it after all! I will get a Raspi replacement from SolarAssistant (bought it along the with software as a kit) so this is good. Anyways, setting up Solar Assistant is a breeze and it comes as an image you put on a memory card and then you configure it via a web interface. One more thing to consider one day... Thanks for your work by the way - it's helping me and others and you are fun to watch.

An extra feature, and worthy, is that the shunt measures a far more accurate battery voltage, and the value can be shared over Bluetooth to feed the MPPT chargers with the more accurate figure. You do need to create the Bluetooth network in the settings, well at least the BMV-712 allows this... The chargers, especially if pumping amps, will be affected by the resistance of the cables, reading higher than true terminal voltage.

Apparently the BYD Atto 3 will only charge at 7kW through the onboard AC charger, but can charge at 80 kW at a DC charger. Like you I have the room to put more solar panels and am thinking of putting a ground mounted array to charge a battery system. Things I would like to know are around DC voltage drop, cable size and length for a given distance to the EV. With the tsunami of interest in EV's by Australians now I think quite a few people would be interested in your point of view regarding what onboard chargers are in EV's, and options for DIY AC and DC charging.

HI! Thank you for your fantastic videos! I built 4 parallelled 16s Lifepo4 batteries and right now I am thinking about adding Victron Smart Shunt to my system. The only thing I really dont understand is - where do I install it? (Position). Each one of my batteries is connected to two massiv busbars which distribute to two MPPT 450/100 and two MP5000. Where and how would you install a smartshunt in my case? Thank You :)

@OffGridGarageAustralia Жыл бұрын

The shunt needs to go between the bus bars and the batteries. Maybe consider installing a second pair of bus bars to connect the MPPTs and load to. The shunt goes in between the two sets of busbars then.

Andy I'm having trouble with my Victron smart shunt I have two separate 120ah battery Banks on the Shunt but once I get down to 50% or burn the first 120ah it doesn't tell me how much remaining time I have no more and every time I get close to burning the first 120ah it tells me I have very little time left as if I only have one 120ah battery connected to it

I've just arranged an Amazon returns on the Smart Shunt after reading a comment on Will Prowse's review. One comment there said that if you log out of bluetooth, when you go back in, it resets the SOC to 100%? Is this correct?

If you install the victron smart shunt between bms and cells, what happens in the event of a bms shut down when your victron mppt is reading voltage from the smart shunt? The mppt will no longer be connected to the battery but it will still be reading battery voltage. I have heard that you will get a high voltage on the bus that might damage other kit like a victron orion for example

@OffGridGarageAustralia 11 ай бұрын

You don't do that! Battery - BMS - Shunt. The battery and the BMS belong together as a unit. Disconnecting the MPPT from the battery is not a problem. The Victron MPPTs will go into Absorption mode and still deliver power at this voltage to the load (if there is enough sun), even without any battery connected.

hello, your videos are really helpfull , thank you!! ... I am strugling with my battery bank with the exact SOC (Electric vehicle, 32S 108V, 200ah, LiFePo4) ... I want to buy a smart shunt but this one you describe goes just up to 48v ... right? ... do you have maybe any recommendation for my bank? ... it works for 108Volts and can get current peaks of like 350Amp :) Thanks a lot in advance!! 😅😅

Sorry, no, I would have no recommendation for that. 108V DC is far beyond any DIY voltage and can be quite dangerous. You won't find many devices for this voltage...

Hey Andy, again a great video, your explanations are awsome. our setup is nearly the same with a Multiplus 2, a MMPT, a Cerbo and a Power In bus bar. quick question to the parameter "charged voltage". This must be the same as configured in the ESS assistent of the Multiplus, rigth? And the "Tail current" is a flexible or fixed parameter? Is it good/not good to set it different? Thanks in advance for your thoughts.

@OffGridGarageAustralia Жыл бұрын

Thanks Thomas, The charged voltage in the shunt is just there to reset the shunt to 100%SOC. So, it should be a bit lower than your actual max charge voltage in your ESS. Say you have 55.2V in the ESS, set the shunt to 55V. To reset the shunt to 100% you need: - the charged voltage reached - the tail current reached (so actual current must be under the set tail current) - the time must be met. As an example the shunt will be resetting to 100% if - 55V is reached - the charge current is under 10A - and above conditions are met for 5 min

@@OffGridGarageAustralia Thanks Andy for your comments, I really appreciate. the tail current with this 0,50% in your video is by default? which number is good to choose here? or should i look at the current of the lowest load i have in the system? whats your thoughts on this? And another question regarding the charge efficiency factor: should this parameter equal to the one in the ESS or also lower/higher? Thanks again for yout thoughts also on that.

Surely the JK BMS has a shunt. It reads current and coulomb counts for remaining capacity. Though I found I had to enter a reduced value for capacity as my charge controller end limits reduce my accessible capacity. With this tweak this BMS shunt functioned perfectly. It sets 100% SOC automatically as the highest incoming coulomb count it ever receives, then calculates the rest from your entered Ah capacity figure and its measured current.

@OffGridGarageAustralia Жыл бұрын

As you have seen the JK showed 39%SOC, so was way off the true SOC. Well, what I call true SOC. The shunts in the BMS have just not the capabilities of such a fine tuning to be more precise, I found.

@mightymouse2023 Жыл бұрын

@@OffGridGarageAustralia It did take a while to get useful truthful figures on my JKBMS. Once JKBMS had top balanced I could safely set my charge controller to max out at 56volts and the JK automatically defines this as 100% SOC after first charge cycle.😊 Then as my inverter cuts out at 44 volts I had to enter my 280Ah cells as only 255Ah on the JKBMS to get a useful 0% SOC value. 😁From then it was plain sailing. ( Or at least plain enough to stop me emptying my whole system just to top up my electric car! and this leaves me a small hidden reserve to run the freezer overnight) 👌 Thanks for the thought and experiment inspiring channel.

@omarfarhat9583 Жыл бұрын

Hi, Andy. I love your videos. Great job. I have a victron smart shunt and I love the features, however, there is one feature I don't understand: the cycle count. It only increments the cycle count by one if the previous discharge was deeper than 60 or 65 % (% SOC). I don't understand how victron thinks this makes sense! Let me illustrate how this is a problem: my battery bank has been cycled between 80% SOC and 100% SOC probably over 50 times but the cycle count is still at 1 !!! Because only once the SOC went below 60% .... that just doesn't make sense to me... it should add up each mini cycle and every time the sum equals a full cycle it should register as a full cycle... right?

Thanks, Omar. Mine also counts micro cycles from 10-20% and back. That's what I do for weeks now during winter and the count is going up. Very slowly of course...

Hi Andy. Whenever my Victron Scc reaches FLOAT mode I SYNCHRONIZE the Smart Shunt to 100%. And CALIBRATE current to ZERO since no current flows at this mode. Is that ok? I followed your settings to Absorption=3.45v and Float=3.35v. Timely video btw. The entire ecosystem of offgrid has so many moving parts. Its just impossible to know them all. You are a great help to us.

@OffGridGarageAustralia Жыл бұрын

That is OK, Noel. Just you will hit the Float voltage far earlier than Absorption. How do you do that? The shunt may reset whenever you hit 3.35V which could be 70-80%SOC only.

The BMS (and Balancer) also consumes Ah on pack side, not measured by the shunt. Would be interesting the self consumption of the BMS. My JBD has probaly a very high consumption due to the huge Relaise instead of MOSFETs.
