Thank you for watching.
Great video and thank you for doing it. Just installed my shunt and nearly fell over when I learnt I had to set it up. Found your vid.. Perfect.
Excellent video, thanks for helping me out
As a complete beginner this video has made everything so clear I now feel I can setup my own system so thank you !!
Thank you. I just installed a smart shunt in a Tab 400 with two 6v AGM batteries and I’m trying to figure this out. This is a great start. Very helpful. Cheers!
Thanks you so much - great informative Video
Nice explanation and covered a couple of personally relevant items that I haven’t seen covered anywhere else.👌
Really useful video, thanks chaps!
That was a really useful video as I've recently upgraded to lithium. Keep up the great advice 👍
Fantastic information guys just bought a victron shunt as a novice you really helped me out 😊 thankyou.
Glad to help
Always trust a man with a beard. I've been using Victron products ever since I started messing around building home solar projects. Victron build quality cant be beat. Thanks guys👍
Thanks again for the useful info 🙂
Does the Auxiliary lead from the shunt back to the dc2dc charger, vehicle battery side work with an isolated charger ,asking as you were using - the body earthing
Very well explained 👍
Great video guys....and great to meet you both at last weekend's show in Harrogate. I've just had a SmartShunt fitted to our CV40 campervan so will be following your video advice to set it up with my dual 100ah lead acid leisure battery system. I don't intend monitoring my starter battery or temperature via the aux input so do I set it to 'Mid point' or 'None' given I have two 100ah batteries connected together? Also will you be doing a future video on connecting the Cerbo GX as adding a screen might be a future upgrade?
Great video guys! quick one on the small red positive wires that you connected did you have an inline fuse on both of them wires? Cheers guys
Yes we do
Hi, great video! I have 2 leisure batteries on my van, both 110 amp, in settings on Smart Shunt for battery capacity do I enter 220 or 110? Thanks
220!
Very nice--thank you for posting. Quick question: Is it acceptable to connect the small positive wire to the positive bus bar--instead of the battery switch shown in the video?
The reason we don’t do that is for troubleshooting. we feel it’s important to always have power to the shunt. If the main fuse was to ever blow the shunt would loose power if it was on the bus bar. If it was on the battery That would be the first thing to check why the system wasn’t working. If it was the main fuse that blew you could still log into the shunt and see the state of charge on the battery
Fantastically clear video! One thing though, I have 2 sealed lead acid 110amp batteries, what should I set the settings to?
Me to 380 amp. 2 battery 🔋 is 740 amp ?
Great video on the Shunt.I have the basic smart shunt.
I want a to measure charge/discharge of my troll motor batteries.they are 2 12volt AGM in series to create 24 volts for troll motor.each battery is also connected to a shore power battery charger when I return from fishing.would you please briefly describe the connections for this.thanks John
Hi, have 3 smart solar chargers in parallel with parallel battery bank. The 100/30 is receiving current and voltage. The 100/20 and 100/50 are only receiving voltage. All show good blue tooth strength. Can you comment on this situation? I guess the 100/30 is the allocated master charger in the network, and coordinates the entire charging network on the basis of its use of external battery current sense from SmartShunt.
The last 3 battery settings disregarding zero current calibration are… “keep SOC” as you recommend
State of charge…. -
Synchronise SOC to 100%. ??? What is this for? Do I press blue synchronise when battery reaches the 14.4V recommended boost charge voltage for my batteries?
Another question is true capacity of batteries. Nominal capacity entered is 510Ahr. I presume Ahr count is 0 at full charge and 100% synchronisation, and usable battery capacity is revealed when batteries reach the 12.9V 20% floor. This would then give an estimate of true capacity of battery bank.
Thanks, DG
If you still need an answer to this, ping me an email contact@bluefix.co.uk
@@BlueFix system established now and on auto mostly. I view soc as approximate and don’t take much notice of it unless below 40%. Have capacity estimate at about 300 from 20% to 90% approx, so a little on the low side, and synchronise to 100% occasionally.
The main issue is was erratic charging but determined this is due to insufficient power for all chargers. In full sunlight they run at capacity. Partial sun light I get more output using just one charger at a time. Cheers
Hi can we ask a question please. We have two * 110amp lithium fitted and a victron shunt.
Arrived on site definitely on 100% charge as it’d been plugged in.
Used 12V TV and lights and blown air heating which we think is about 5% used (roughly 3 hours)
Then used CPAP machine overnight which is 50w for 8 hours.
So we think the CPAP alone wouod use about 15% of the 220amp hours we have.
However this AM we awoke to 93% charge when we expected abouy 80%.
Today we’ve had some medium solar for 6 hours. Which apparently topped the batteries back to 100% however we believe it’s reading too high. The voltage says we are on 13.25 but the battery reading is still showing as 99%
This is a new system. Do we need to calibrate it? It was professionally fitted
Is it ok to run my vehicle chassis grounds (engine block, firewall, and fender) to system minus? I’ve had mine wired this way on my Jeep for several months now, and haven’t had any issues. Someone recently pointed out to me that it might be dangerous and now I’m doubting myself. I have a Jeep TJ with a non-smart alternator and 4.0L engine.
G’day boys, I have a lithium 200ah with this shunt and was wondering if I set it up in the settings as you did in video for the 100 lithium? I’ve only just found your channel and think it’s the best explained video on UA-cam for my needs, thx mate. When do you think you’ll drop the follow up video where you mentioned going into more detail with each setting and why? Thx again for your work much appreciated…
Question I have just fitted a smart shunt we have two 150ah batteries I have set it to 150ah should is that right or should I put it to 300ah
300ah. Total amp hours
I have 2 banks of 6 eg4 batteries (not LL). Needing a wiring diagram to connect my 500A smart shunt to them. Banks are parallel to parallel. Pairing off on th😊e two negatives. Thanks.
I note you didn’t change the Peukert exponent back to 1.25. Was that an oversight or is the 1.05 setting suitable for lithium’s and AGM’s?
can the cable between the battery and battery minus on the shunt be a longer cable? In my application it would be easier if the shunt was about 6 feet away. It will still be between the battery and the negative bus bar.
Yes, it can be but make sure the lengths of your pos and neg cables are of a similar length. Watch out for voltage drop too.
Just purchased and installed a smart shunt in my Moho but I’ve got a very basic 12v system. AGM starter battery and a lead acid 80amp/h leisure battery. There is a 100w Truma solar panel with a Truma controller. I’ve installed it changed the settings to match the battery and changed some other settings to match your video.
I want to monitor the AGM starter battery but that’s got different settings how does the app allow for this?
You simply select starter battery monitor from the aux options, there is no configuration requirement because it’s just monitoring the voltage and nothing else.
@@BlueFix thanks I’ve now connected with the starter battery and it’s all working great.
Great video... What is proper way to wire shunt to 3 parallel batteries ?
Im new to all of this and do not have any knowledge of how to hook up the things up that I want to use to power up my fridge in my off grid cabin. I want to power a 12 volt refrigerator with a 200 amp lifepo4 battery for use in my cabin. For right now, I will take the battery home to charge it until I can afford a solar panel. What size of a Victron shunt do I need for a 200 amp battery and how do I hook it up?
Hey guys great video I used your settings to set my shunt up to my 110amp lithium but for reason it won't always read 100% capacity even though it's fully charged any ideas?
Hey Anothony, I might be able to help. Charged voltage should be higher than 13.6V for lithium, 14.2-14.4V is good, 13.6 is too low and won't say your battery is at 100%. Hope this helps!
Can this be used on a 36v lithium?
Tail current is 4% of battery capacity. If you have 2 x 110 amp batteries is that 4% of 110 or 220? Is it correct that when your charge current drops below tail current that means your battery is fully charged? Trying to figure out if my 2 x 110 amp batteries are fully charged,
4% combined capacity
Great video guys! Quick question - I want to measure my starter battery with the shunt and I have the same setup as you. So I will run the "Aux" positive into the Orion input. Now do I also have to run the negative from the starter to the "Battery" side of the shunt too? Thanks!
Nope. Just do the aux as you said 👍
@@BlueFix shot guys!
Thanks Guys
I have two 200 amph lithium batteries in parallel, do I set up my shunt for 200 amph or 400 amph?
Thank for the question , Assuming you are running a 12v system, 2x 200ah batteries in parallel you would set your shunt for 12v 400ah
Another good video guys! Love how your breaking down & explaining each component! I’ve fitted a new system & have a few teething problems… do you guys offer a service to check over & explain where/if I’ve messed up
Yea we do drop us an email. contact@bluefix.co.uk 👍😁
If you can only connect the negative cable from the shunt to the negative post of the battery how would I get the negative cable coming from my solar controller to the negative post of my battery for the solar controller to be able to charge my battery
We use bus bars. You can get an example here ua-cam.com/video/4hgMk9-tYzA/v-deo.html
for the AGM settings, you skipped the peukert exponent .. what should that be?
Did you test the accuracy with Victron Smart Shunt? In several test we have made it always shows approx 3,5% less capacity.
Ive found that its all about the minute details, ive had a set of self built lithiums for 4 years and it took me 2 years to fettle in the settings! Its now pretty much spot on, and when charging will count down the used energy perfectly to 100%
Hi Guys , so I'm thinking of fitting a victron smart shunt , but I have two XV110 Hankook XV Leisure Battery's.
My question is , what category would my batteries come under ?
AGM or Lithium ?
If anyone else knows I would appreciate a reply.
Great videos and content guys.
They would be AGM batteries. Thanks for the positive feedback!!
I just connected my smart shunt. Can you tell me in the settings what the charged voltage means and what should be the correct setting? I've seen quite a few videos with different settings. I've seen 13.5 13.6 13.8 14.4 14.6. Which is correct? I have lifepo4 batteries.
Good question! I can say it is not 13.5V at least because I tested it and when you discharge like 10Ah and soon as you Solar charges like 10 minutes (one small panel only) it says 100% SOC and that is not right! I think it must be 14.4 or 14.6 but have to test it some more.
@@april7_ I have it set to 14.4
What did you call me 😂😂😂😂😂. Best joke on youtube this year 🤣
What busbar brand is that ?
Great video thanks. I want a dc to dc fitted and a smart shunt .email you when I save up.
Can I connect a starter lead battery and a consumer Lifepo4 battery?
you can charge your Lifep04 battery from your starter using a dc to dc charger like the Victron Orion TR Smart. But you should not connect them directly together.
Can’t really find the answer in the product documentation. Can this be used with two batteries in parallel? Assume so, it would just read them as a single 100Ah battery instead of separate 50Ah batteries.
A bit confused why you claim a '13.5' % for Lithium but higher for AGM?? Most Lithium batteries are at or near 14.2-14.6V, period. Curious...
Lithium batteries charge at a lower voltage then AGMs
The "charged" voltage should be 14v other for lithium,your soc will be wrong otherwise,
torque specs?
Charged voltage at 13.5??? So when the SS senses the battery at 13.5 and meets the tail current parameter it will record 100%. I have seen this set much higher by most everyone else.
Torque specs around 2.5nm for 10mm on brass. Those settings are typical for the Victron branded LiFp04 batteries. It really does depend on the battery cells, on EcoTree 230ah we use 14.2/13.6, tail current 3% (6.9 a) PE 1.05 and CE 99%
Strange settings guys
Jonas explained the charged voltage needs to be 0.2v lower then the mppt absorption
So says you have 14.4v absorption and 13.5v float
In the shunt it should be 14.2v and 13.5v float
I tried these settings but you don’t get a correct sync
But each to their own
The Victron Lifepo04 setting is 14.2 float, 13.5 charged (cold) voltage. I have found that 13.6 is a better charged voltage and it stops the shunt setting to 100% too early.
This is not a shunt, this is a battery monitor without a display.
I am only looking for a shunt for ampere measurement suitable for the victron VRM system.
I am really happy to see you guys really good explained i have been this business for last 4 years.
LOL.... Count the electrons?
Why did you fix the shunt upside down, did you make it on a friday.
he says make sure the batery post is clean so he rubs it with his oily thamb and then attaches the lug ?.
