I think there is a firmware release, you can set voltage/time ... tail .. before shunt consider the battery is 100% or 0%.
Thanks for the nice review.. !
EXCELLENT REVIEW! just ordered one off your link. this is exactly what I need!! thanks,
jim
Your very welcome! What do you have for a system?
@@Roll2Videos well starting over because I just had a fire and it was a total loss. have 2kw of panels. just got my EG4 6,000 what split phase. that's replacing all my cheap chinese stuff. my old system ean great for 4 years, ran my water pump, window air charger my tool batteries and 22 volt trailer batteries. I was only 24 volt and a 3kw inverter so I had to turn off a/c to microwave or run my bladder pump. but I had a little control center on my kitchen table with remote start of my generator so it really wasn't a hassle for me. we are 100% off grid. building a cabin
just sold our house and the next day we got the call our travel trailer on our lot was burning! bad timing. but now we are buying high end equipment that is u.l. listed so we can transfer it over to the cabin legally when the time comes. my wife said the daly bms came yesterday and hoping to get the 16 lithium batteries next week. building a block shed with metal roof to contain all our electrical lol as we are very paranoid of a fire again. I suspect it was my window air, as it blew the breaker twice 5 days before the fire while I was up here. I shrugged it off as just being a hot day....
should have shut everything down when I left. but I got spoiled coming up to a cool trailer, with cold food and beer in the fridge when i arrived!@ lol
never in a million years thought this would every happen. now i have till October 30th to get everything back to liveable and we are here full time as of that date!!
sorry for the book.... so I'll be runnking 16-285 amp lithium with a daly 250 amp BMW into the EG4 6000 kw hybrid charger, 12 panels, 4 strings into a 4 string echo distribution box with breakers, out into EG4, out into a sub-panel to my loads which is basically 30 amps to travel trailer. 20 Amps to bladder pump, 15 amps auxiliary gfi receptacle. my 6500 generator will be power in for now until we get the house check, then we arr buying a 24 kw propane generac with auto start triggered from the EG4 when needed.
really appointed you techies sharing your knowledge, no way I could have gotten off grid which has been my dream for years with your help!
oh ya, I have a lead acid back up ( 4 x 100 amp ) for really cold mornings when the bms temps out.
your battery monitor will come in really handy for keeping tabs on when I need to run generator until I can figure remote monitoring on the EG4.
have a great day brother,
thanks,
Jim
@@John-bb4wk OMG! That is one crazy story!
Defiantly should have noted the breaker issue (Live and learn) Sounds like you have a plan to move forward which is great. Ever thought of documenting it on RUclips?
Thanks for this video. I just ordered this based on your review.
I have 3 of them 😁 1 for my off grid trailer, 1 on my golf cart and 1 extra for future projects 😁😁
@@Roll2Videos Awesome. Can't wait to get mine too :)
I ordered it too on your review! 😊
Thanks for the review, I have been looking for a reasonably priced alt to the “top tier” units,I am assembling a modest backup for the increasing hurricane activity in Atlatic Canada and want keep it simple I have ordered this unit with the display , I really don’t want or need another app, I actively look for hardware solutions . Too much screen time for devices that really distract, thanks for your through and thoughtful review..subscribed
Thank you for the kind words 👍
Good job,nice review. Does seem like a nice little device & App, I would get the screen also as a backup in case something goes wrong with the Bluetooth down the track.
Im presently considering different ways I could setup a ‘Solar Dump’, to offload power when batteries are full into a smallish Hotwater system for a bus with a 24v 3kw AIO system. My 10kw of batteries are full by midday so I figure I could use that extra power available to heat some water instead of using gas.
Q) can this shunt be used in this way with a relay to close a set of contacts at a high SOC? Or is it only configured for a low SOC cutoff? Thanks for this info. Cheers
You can set it up in this way with voltage unfortunately SOC option is not available.
Cool review. For the small price I would get the screen as well. Does that app have a landscape mode? Thinking that it could be used along with other apps that are in landscape mode.
I've ordered the screen 👍 It works in landscape mode
@@Roll2Videosdónde se puede conseguir sólo la pantalla?
@@dad9597 I only know English, sorry
Does this have a low voltage cut off feature to help protect batteries that are getting to low? Like a low voltage disconnect?
Yes it does, you will need to run the power wire through a relay the shunt itself does not disconnect.
I purchased this if seems to work really well I wanted to be able to see what my DC to DC charger was doing while I was driving hopefully the battery percentage starts to work at the moment it seems frozen at whatever present I put it at
Oh no! I haven't had that problem reach out to the company everytime I've had a question they answered it. Keep me up to date on your progress please
The screens worth getting as i can have a quick look in my camper than look on phone
I have a question for you sir, does the display have to be connected to use the phone app. I'm running out of room for a location to mount the display if I were to buy. Never mind I just saw the end of your video about buying the screen
Lol, No the screen does not have to be attached.... Oh I just seen the end of your comment. 😂
Ok, I could swear I saw your comment below that you had a video coming out to view the battery monitor over wifi!!! My battery install is at the tail end of my 35' trailer/camper so not sure bluetooth will reach to the cab of my truck while driving. Look forward to that vid or please just point me in the right direction. thx!
Also, I have the Growatt 24v/3000 that takes in 141A DC input...I assume I should get the 400A monitor?? Thx
It should reach the cab the Bluetooth is pretty strong. My method of over wifi I doubt will work for you I show it in my "smart off grid devices" video
@@Roll2Videos Thanks, I'm going to give it a shot
Hi . Do you no if you can trigger the relay output via state of charge.
I want to trigger my water heaters 1hr boost on when Soc reaches 100% on lithium so should be very accurate.
Thanks
Not the SOC, but you could use overvoltage to trigger the relay at the top end.
Do you know of a shorter cable that will work from the main display to the controller box. I need a 3 foot cable.
The unit comes with a cable. You'd have to match it if you'd like a shorter one. I'm not sure what the cable is.
Cut the ends, extend the wire and match up the wires on the ends. Simple to make any length
Are the cable bolts fitted for 5/16 lugs? I don't see it on the manual. I downloaded it and I can't find anything about the lug sizes
It's a 3/8 lug.
Roll2, I have the KG-F Series Coulometer paired with a 100AH LIFePO battery. I cannot get the Battery Remaining Capacity (Battery remaining % image on the Display) to report Percent Capacity based on the remining voltage of the battery. I’ve tried fully charging the battery, then setting the Coulometer AH Rmn to the value on the display (Vs. setting the AH to the 100AH value on the front of the battery), but the Coulometer Percent Capacity image doesn’t move or is incorrect based on the current Volage reading on the Coulometer Display. Any idea what I am doing wrong or how to fix this? Doug F.
LifePO4 is tricky. The voltage doesn't sag like lead acid. It is very difficult to judge state of charge off of voltage. Google LifePO4 discharge cart you'll see the line is pretty much straight.
Do a discharge test. Take a known current draw and see if you get close to 100Ah.
hi there is a software that connects a windows10 pc to the rs485 socket to manage with PC as for BMS Daly ???
I don't know
How to hook up a relay. Using a 300Ah Lithium battery with a 2500W inverter. Parts and installation.
Greetings, is there any way that battery monitor can be used in connection with growat? communication port?
No, I don't think so. I use solar assistant with a Victron shunt. I have newer videos showing the connection in my 48V server rack cabinet build. 🍻
hello, does this voltage meter work with 48v batteries?? and does it take the power from the battery you control or does it need an additional external power supply .. ?
This monitor will work with 48V batteries. You can use the battery to power or a external supply
I would like to know if there is a link where I can buy only the screen. The link in the comments doesn't work and I haven't been able to find the single screen anywhere. Thank you so much.
It's not easy to find just the screen. I have in the past.
Good video. Thank you.
Thank you for the comment, I was my pleasure 😁
Will this work for a tubular flooded lead acid battery?
Hello my friend. I want to ask a question.
I have 4 gel batteries of 105 amps.
and I connected these batteries to each other in parallel.
As a result of the parallel connection, a power of 105 x 4 = 420 amps was generated.
that is, + poles and - poles are connected to each other. and I have a charger that charges 50 amps. I want to see the current amperage, the charge level of the batteries, and the amperage, volts and battery percentage after the charge is finished. Will the tool you shared this video of work for me? Or what is your suggestion? Any help would be appreciated. thanks.
Yes this will work for you, With your type of battery it falls under lead acid. Lead acid shouldn't be discharged below 50% state of charge. Therefore below 11.4V.
You have 210 Ah If you discharge more your battery won't last a very long time.
Hey bud, I just installed the KG140, it's similar. You should try to update the firmware, it may give you the Low Temp protection feature.
I did one update initially, but that feature wasn't listed still, but I just read that you need to do two updates... I haven't ran the second one yet myself.
If you just press Update, the app icon just swirls and hangs. The process to do it is: Unplug Temp sensor if connected, short those two Temp sensor pins, THEN click the Update icon.
Thank you I have done the update. What do you think of the shunt? Also I have a video coming out next that shows how to view your shunts Bluetooth over the wifi from anywhere. 😁
@@Roll2Videos We spoke recently about LiPo battery/BMS/safety... I mentioned that I'm easing in to all this, but learning a TON from your experience and videos, thank-you. You strike me as an Albertan... 😁 That's where I'm at.
So, this is my first shunt, I threw her on our old RV running 2x 6v golf cart batteries. The RV came with an 80w (I'm told) panel on the roof and a very basic 20a controller.
I felt like I was running blind, never knowing how much we drew down and replenished. Only just got the shunt installed last night, so far, it's amazing.
I'd like to put it through some load tests over the next few days, so I know my baseline service consumption, then see the recharge rate. I'll feel better knowing those details before camping next.
I can't wait to see how you hook the shunt up to WIFI!
Cheers.
@@Roll2Videos any update on this hack?
@@leviahamefula3994 Yes, when you buy the shut, it comes preloaded with the low-temperature relay option.
@@Roll2Videos ok, but I meant the Bluetooth over WiFi thing you mentioned in your earlier comment.
Is your shunt still working after a year, since you first posted this video?
Yes, I use it all the time
There is any way to I integrate this on Home assistant?
Thank you
I don't know., I used the Victron shut with my Solar assistant. 🫤
A few questions. I have 3X 105 AH AGM in Parallel (315 AH). Can I hook up on ANY batteries in the bank or does it need to be on a specific battery? What type of battery should i set the monitor for for AGM? Also, with AGM half the AH are useable...so for the monitor do I set it to 315 or half that? How should I read remaining? Would 0% left be 0% or would it be roughly 157.5AH remaining?
You don't need to set the battery type as it counts the Amps running through the device. I would set the usable Ah so yes half of the rating on AGM.
Do not mix the battery chemistry they use different voltages and charging algorithms 😁👍
@@Roll2Videos Thanks! Can I hook up on ANY batteries in the bank or does it need to be on a specific battery? i.e. could I use the center battery?
@@cardinhamkilligrew9712 it will need to be on the negative cable in-between the battery bank and the load.
@@Roll2Videos so the negative going out to the house? What about positive?
@@cardinhamkilligrew9712 negative wire from the battery Bank to the inverter, you must install a small positive wire to sense the voltage.
Hi, I need a monitoring device for an 24s7p 28Ah li ion pack for an electric paramotor. The engine will pull max 23kw at 70-100v and max 260A. Do you think this device is appropiate? I saw others entering sleep mode 0-60sec do do you think I can dissable that if it has? The shunt Gets pretty hot, unless I'l be using the 400A one..maybe, and because I don.t want another consumer besides wires, battery heat, motor losses, etc shall I use a hall sensor device instead of the shunt ones? Thank you!
This shunt will work for you Go with the 400a one, mine never enters sleep mode I have to disconnect the positive wire on my golf cart for the winter storage. 🍻
Thank you! Did you find out if it keeps the settings if it is umpluged for days?
@@Seneslau07 yes, It keeps them
ciao , questo misuratore di tensione funziona con batterie da 48v ?? e l'alimentazione la prende dalla batteria che controlli o necessita di una alimentazione esterna supplementare .. ?
English?
Does this still graph the power usage even if not in the app? (Will the history load when connected?) Victron wipes the graph data every time the app loads making it useless.
It keeps the memory of usage even when not connected. It's my favorite shunt by far
@@Roll2Videos THANKS!! One more question. Does it still keep the memory if the display is NOT used/unplugged? Display would be turned off to save power, and turned on when needed to be viewed. (But mostly would use the app, so need to waste power with the display, but I still need/want the history)
@@Mogalize I want to say yes but not 100% I can test it out next time I'm at my off grid set up. Next week I'll be going.
This device
Can it be connected to batteries in parallel? Could you add the two batteries?
Yes
Where do we find a relay to add to this unit? If I'm running a 12v system will any 2 prong relay work? And likewise when I make a 24v or 48v system should I look for a 2 prong those voltage relays?
Yes, Any relay with a positive and negative to power it. Make sure the relay is rated for the voltage and amperage you're using. 👍
@@Roll2Videos I’m a bit confused at the relays on Amazon, the confusing part is trying to figure out if it’s open or closed in normal state, I don’t want to buy one and it’s open in resting state, and not power things in my build.
@@tinyhomeincred-i-box look for "NO" and "NC"
It's Amazon easy to return if you get it wrong.

How is your amp draw?
@@Roll2Videos what do you mean? Do I size it by the max amps I intend on drawing at one time or the battery total. 660 total ah. Probably use 100 to 150 ah each day....so like 10 to 20 amps at any given time

Can you still get info on how the system is running via the app if you're away from home?
You could if you had a extra smartphone. I use the app Team viewer. It's free to remotely control a smartphone.
@@Roll2Videos gotcha thx
Just something that bothering me .. 9:32 : You got 15 Ah remaining and load is at 2A... why the "Battery Left" display ... 7 mins .. ! Should be 7.5 Hours .. (15/2)
Those time estimations on every shunt are always wrong. I never look at them.
ciao esiste un software che collega un pc windows10 alla presa rs485 per gestire con PC come per BMS Daly ???
🤷
Hi i ave 2 agm 12v 100ah bank in my camper do i ave set 200ah on thé dévies
You can start with that when the batteries are full, but when your batteries reach 11.4V, that should be your 0℅ with lead acid. Then do math and input your accrual capacity over all.
My guess would be 100Ah. Lead acid shouldn't be discharged more than 50%
Same software for VAC8810F ?
No, difference app.
Is the screen Bluetooth and what is the range
The screen is hardwired. The bluetooth to mobile has an excellent range.
can I use it also for 48 vdc battery?????

First and foremost no disrespect to the poster of this video…..Nutz !! Being a person concerned about the environment I made a commitment to leave off my electricity guzzling desktop in favor of a “docked” galaxy S10 displayed on my tv (dex mode) I use it as a dashboard for tasmota devices, my security cameras and this meter via the Bluetooth app ? So, I hook up this device, 8 vertical feet away from my basement and.. it doesn’t receive the meters Bluetooth signal. I remove the phone from the dock, go down stairs, receive it then never loose the signal UNTIL the exact moment I reDOCk my phone. All of my other Bluetooth devices work fine in dock but this app Doesn’t ! Furthermore it does the exact thing with my docked S6 tablet on a completely different dock and well filtered power supply.

Good read, Sucks it's not working the way you need it to.
Too bad it's only available on aliexpress unreliable source.
Unfortunately sometimes they are
Smart phones are an addictive waste of time that distract you from life itself as you are looking down at them. A home PC is all anyone needs. While you are gawking at your phone for this unneeded function you are missing life as it passes by. A voltmeter is fully adequate.
A simple light weight digital voltage meter is cheap and there are no radio emissions, no $1,000 investment, no monthly service fee, no need to keep it charged and no way to hack it. There is no wait time at all to glance at a meter and if you lose it in the water you won't cry. In addition, when you carry a phone you will never learn self sufficient navigation.
What's the bluetooth password?
I can't remember if there was one. Pretty sure it just connected through the app without one
mine asks for the password.
