You can not imagine how many people like me are out there trying to set up their smart shunt and have zero clue what we are doing. I am currently on the road traveling long term with my family and needed this information desperately to make sure we are using our batteries wisely. Thank you so much. Everything makes sense now. You have a new fan!
Thank you... I have been using a Victron Shunt for several years and I get 100% reading when I know it is not forever, but I had no idea how to fix it... 😊
I have plainly been using the wrong settings for my 120ah Lifepo4 which explains the fact that I did not have the 60% SOC while van was off the road that I thought I had. Going with your advice tomorrow. Brilliantly explained thank you.
I just bought my first lithium batteries and smart shunt and was struggling to figure out how to set all the settings. This video was exceptional and extremely helpful, I am thrilled that I found your channel and thank you so much for your thorough explanation!
Great video I have 48 V Lifepo4 system I was having trouble trying to determine the charge voltage for the Victron shunt. I couldn't work out why the system cut out early but with the help of your video my charge voltage was set too low Thanks great info
I'd loved to have gotten all victron components when I was shopping for everything. At the time I was new to solar and couldn't justify the price in my mind. Now I see so many features victron provides that I would like to have now. They are expensive and complicated but they are unmatched in so many areas.
Nicely Done Video! One of the thing most of the video's don't show is setting when you have a 24v setup or in my case one (1) Dakota Lithium 36v 63amh battery for my trolling motor. Many video's are using just one (1) 12v setup. It just would be helpful to have that other battery configurations touched on for newbies trying to figure the correct settings. Thanks for your very detailed video!
You can add me to those few who have gone bigger than normal. I have two 460Ah LFP's for 920Ah. I had planned on going with a DYI build with 16 280Ah cells in either a couple of 2p4s configurations or by paralleling four 4s pack for a total of 1120Ah. All of these would fit into the battery tray made for (6) golf cart batteries.
The official Victron manual is written very poorly. It says "The charged voltage parameter should be set to 0.2V or 0.3V below the float voltage of the charger." My CTEK D250SE charger has a float voltage of 13.3V for lithium. So according to Victron, I should have my Charged Voltage set to 13.1V. The manual doesn't give any advice for tail current or charged detection time. Definitely not consumer friendly. Thanks for doing the video that victron should have done themselves.
Hi Rog, good video thanks, I am a bit concerned about the Battery capacity setting though, you need to be clear about series and parallel, 280 x 16 like I have in a 48 volt system is just 280AH as they are in series to make 48 volt, a 12 volt 280 would be 280 but if you have two in parallel then 560, so in parallel add them, but in series dont, what you say is not really clear. Bob
Thanks for the clarification! a very important detail. I'm a total newb, but it was vague enough to set the mental alarms ringing for my 24v series string of 2x 100ah LiFePo4 batteries. I had to check else ware to be 100 % sure. I know its electronics 101 but you can't afford to guess and just hope for the best with this kind of stuff!
Very helpful..one of my 500amp shunts is losing sync and when i wake it shows pulling 125 watts daily and the battery is at a 100%..even with no Sun..i normally drain it to 60 perc soc at night..then i need to do a whole clear cache..uninstall and reinstall..android btw..its also connected to a cerbo gx..can anyone advise on what the issue might be..even i switch the pv disconnect to off..still says 125 watts coming in..
Hello good afternoon, thanks for sharing this video… I have 8. 12v valve regulated lead acid batteries to make up my 48v. What would you recommend for my charged voltage?
You need to qualify the amp hour calculation for newbies. If you put batteries in series, you don't add the Amp hours you add the Voltage. If you put batteries in parallel you add the amp hours. In the example in the video a 12.8V (4P) system is 1120Ah, a 25.6V system (2S2P) is 560Ah and a 51.2V (4S) system is 280Ah.
I’m still unsure how to set my battery state of charge. I don’t know what percentage it should be set. How do you know what state your battery is at the time of install.
I am confused on your Peukert's exponent info, I think this is used to calculate (project) the delivered capacity based on the Discharge rate not charge acceptance efficiency. Just curious what you were intending on this one.
Hi, can I control load from one A) 48V battery to other B) 48V battery via Victron 100/20 without solar input in the way to provide that battery A can not discharge to 0%??
Current Threshold 0.1A A solar charge controller and shunt draw about 0.03A Does the system account for idle draw? Only if you lower the threshold to below 0.03 ?
I have 2 100 amps batteries parallel connections on my 2 100 watts solar panels for my backyard lights how is VICTRON SMART SHUNT 500A CONNECTIONS ? THANKS IN ADVANCE
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.
offgrid have a question re my battery charger leads and midpoint connection to smart shunt.cant find this in viltron manga..should I keep charger leads as is going to each battery, or connect as a load, with each positive lead going to first battery, and each negative going to load side of shunt?seems like keeping as is would be the best way? thanks John
Amazed how many people don't read the manual! It's all there!! From Page 22 on is the most helpful. Even so called experts don't get it 100% . Discharge floor is used for the time remaining calculation and alarms, it doesn't disconnect anything that's low voltage disconnects job!

Hi. Can you make a short video where you have two smartshunts with their own separate batterybank. Each of them with one or more mppt. And show How to correctly add all the units to a bluetooth network. Then add a globallink and connect all units via bluetooth only. Explain the differences between System Voltage, Gateway Voltage, and each SmartShunt Voltage. Can VRM indeed handle this? Last But also important. Install the globallink first with no connected units. Does it stay connected for 8 hours straight? After connecting all units, Does it stay connected for 8 hours straight? Add a communication alarm set to 60. And turn the relay to Closed. If you can add some kind of logger to the relay port that would be useful as this will show if, when and How often the globallink has restarted during these tests. I have had issues no one can solve and hope that you can give it a go. Many users have the same issue with abnormal interrupts and restarts.
For the total battery capacity. You didn't mention what type of connection done, Either series or parallel. If series, the total capacity of all batteries connected will the total of one battery(280AH). If connected in parallel, the total battery capacity will be the sum of all batteries which is 1120AH.
Amp hours are not necessarily determined by the number of batteries you have but rather by the battery configuration....if you have two 50ah -12v batteries in series you still have a 50ah battery, it's just a 24v - 50ah battery now. Something I thought needed to be made clear after watching just the beginning of your video...statements like that cause confusion for viewers.

I’m about to fit a SmartShunt to my VW camper and this 😊is by far the best video I’ve seen about it. Thank you!
Excellent video! Victron should hire you. Thanks so much for the answers that Victron themselves seem unable to provide.
Glad it was helpful!
Thank you... I have been using a Victron Shunt for several years and I get 100% reading when I know it is not forever, but I had no idea how to fix it... 😊
Thank you. Sat in my van and coped all your advised settings. Very informative video.

Thank you! My setting had gotten off by 18%. I re-synchronize them. Now that match what the batteries say they are at!
Thank you for the very helpful information.
Thanks for your help! You’re the best
Best description ever! Thank you.
Nice video I Sign up for the detailed Smart Shunt settings PDF and I didn't receive one as yet. Please inform.
Regards,
Apologies, our system should have sent you the link to the document. If you email hello@offgridpower.solutions, we can send it to you.
Great video thank you
Great video, best explanation i've seen on YT, could You do same guide for Multiplus II?
Very good information thank you I’m wondering if the shunt you are referring to is the 500 amp size.
Yes, we were using the 500A version in this video.
Great video. Thanks

Hello! A very good tutorial! Thank you!
Do you have any idea how to set a maximum load limit? For example 90% or 95%, to protect the battery?
Hi Rog, good video thanks, I am a bit concerned about the Battery capacity setting though, you need to be clear about series and parallel, 280 x 16 like I have in a 48 volt system is just 280AH as they are in series to make 48 volt, a 12 volt 280 would be 280 but if you have two in parallel then 560, so in parallel add them, but in series dont, what you say is not really clear.

100000% I am trying to learn about my batteries that are in series and this threw me off.
What should the charge voltage be for lead acid battery’s…😊
I have two 185 Ah lead-acid stationary batteries. Could you please suggest the configuration parameters? Thank you very much for your help !

the battery capacity would be for multiple batteries in parallel right? If the batteries are in series it wouldn't be combined right?
What about for about AGM battery?
We’ll try and get a video for AGM out sometime.
@@offgrid_powerthat would be great!

Current Threshold 0.1A
A solar charge controller and shunt draw about 0.03A
Does the system account for idle draw? Only if you lower the threshold to below 0.03 ?
At 6:24 did you mean to say float voltage? That would make more sense to me. You stated bulk voltage…
Thanks!
My MPPT charger states that absorption stops at 1amp(battery full). So would my tail current be 1% (1.2 amps) as I have a 120ah battery?

Hi. Can you make a short video where you have two smartshunts with their own separate batterybank. Each of them with one or more mppt.
And show How to correctly add all the units to a bluetooth network.
Then add a globallink and connect all units via bluetooth only.
Explain the differences between System Voltage, Gateway Voltage, and each SmartShunt Voltage.
Can VRM indeed handle this?
Last But also important. Install the globallink first with no connected units. Does it stay connected for 8 hours straight?
After connecting all units, Does it stay connected for 8 hours straight?
Add a communication alarm set to 60.
And turn the relay to Closed.
If you can add some kind of logger to the relay port that would be useful as this will show if, when and How often the globallink has restarted during these tests.

Looking at the charged voltage of 14.0V on his screen, it’s obviously a parallel setup connection. However, he may have made it a bit more clearer.
I came to make the same comment. Well done explaining it for those who may be new to this it is an important distinction.
Amp hours are not necessarily determined by the number of batteries you have but rather by the battery configuration....if you have two 50ah -12v batteries in series you still have a 50ah battery, it's just a 24v - 50ah battery now. Something I thought needed to be made clear after watching just the beginning of your video...statements like that cause confusion for viewers.
