Wow. They basically gave the shunt the brains of a BMS! Very cool! Might have to pick one up for my portable power station build. Thanks!
I bought my two shunts based off your video on these before. They have worked perfectly. I’d definitely recommend them. Also, I like the new display.
Thank you, Yes, I saw them in the background of your videos. It made me smile seeing them there 😁
Man you have become top notch video and tester guy for the electrical stuff I have as a hobby.
It's a wonderful hobby
@Roll2 Videos I order the same one but it's under a different name. WonVon it's identical, I hope it's the same one. When you type in Juntek the WonVon is what comes up.
@@mikesterling9322 that is the older model. The link I'm my video is the newer one
@Roll2 Videos awesome does it come with the shunt cover as well. Thank you for the help. Newbie here just learning. 👍
@@mikesterling9322 yes, just not the relay
These guys have great stuff. I've used their old VAT-4300 In almost all my capacity tests over the years. It's been rock solid. I even shorted it out once (my fault) and was easily reparable, still kicking. I have this new one, and can't wait to test it. Great Video!
I'm looking forward to your video 😀
Man I'm wanting to make a video of my system when I get home this time from being on the road all month. I started to do it a few times but I get cold feet ki da worried about what people's gonna say. It's an impressive system with good components but it's still in process of adding more panels.
@@matthewknight5641 Do it, Youll feel better after you post.
@@matthewknight5641 Yup, just do it! Step out of your comfort zone, it'll be good for ya.
Great video, going to pick one of these up.
I have 2 KG140F devices. Even though most of the settings are available in my version, I consider owning these as a necessity evil. First I have to grant location permissions, then file permissions, then when I hit “Firmware update” the software just locks up. The Bluetooth signal doesn’t even penetrate my wood floor ( on either unit when used singularly or when both are used ) I tied using several devices and OSes..eventually I had to move my tablet downstairs and use a dock with hdmi output. Many other Bluetooth tooth devices I own have absolutely no issues. By no means do I consider this device “worthless” rather its another poorly engineered device made in China.. Sincerely I hope someday this company will change my mind. I would happily pay 15 bucks more for them to engineer a better product.
That has not been my experience using multiple of their shunts.
I'm over the road truckdriver but soon as I get home I'm gonna do the low temp cut off deal with smartphone you just showed us. My leaf batteries done have a bms on them and I always worry about that bit the destroying them with charging while to cold has been my biggest fear. I'd love to have the money for a 20 or 30 kw lifepo4 battery
BMS is for protection not shunts. i would call that a stupid feature to have protections in shunt. :)
@@SayWhaaaaaaaaaaaaaaaaaaaaaaat Redundancy fail-safe 👍
Wait .. i can't see anything new in this KH serie vs KG serie .. ! What is different ?
Different display layout, different app. Cover for the shunt to provide more protection.
@@Roll2Videos Yea that's what i saw, but it's a pretty bold move from Junteks, we need to buy new devices to get an update on the app ? As i see, the hardware is strictly the same, only the software is different.
Now since you got the both devices, you just have to open both devices and give us hardware differences...
Question, if the low temp protection kicks in and disconnects the battery from the charge controller wouldn’t that fry the charge controller? I have heard many times on different solar forums not to connect the solar panels to the charge controller without a battery already connected. Thanks for the great video!
It's possible that some older charge controllers may have this issue, but newer models likely don't. It's best to check with the manufacturer.
Allright, i'm near finished the script to flash KH140F firmware aka "new device" to the "old" KG140F... showing how Junteks did not create a new device but just package the same hardware in a slightly different package and sell it as a new device, preventing US, buyers of the KG140F of upgrade that where promised.
Thank you!
I have one of the 400 Amp shunts like that but it's about 6 months older version
The older version is still a keeper
My older shunt came with a temp sensor. Do you think it's capable of doing the low temp cutoff? I know it came with a little plug that says ita a relay wire bit I never really messed with it. I just been using it to see how much runtime and charge time I have and state of charge. If it'll do the temp cut off I'll use it but if not I'm ordering the newer version
@@matthewknight5641 Open the app you're using and see if low-temperature protection is there
I know you have solar assistant will you see if it is possible to use solar assistant with this. Waiting for Orange Pi 3 LTS to come in and now am looking for shunt that will be compatible with solar assistant
The Victron shunt is compatible. I'm using it now. I think I mentioned it in another video with my server rack
Please tell me. Shunt M8 or M10 terminal connector?
M10 👍
Hi, what type of shunt would you recomend to monitor the state of charge of a 24v system, its for a boat trolling motor, I have 2 12v 100ah ampertime batteries connected in series, also wondering if its possible to leave the shunt mounted in the boat or will the wet enviroment be a problem, I watched your video on battery storage and would like to discharge the batteries before storing the boat for winter. thanks for your time, great channel.
The new Victron has an IP65 rating

I started looking for a relay for mine but got sidetracked. I know I couldn't find 1 right away and the couple I did find seemed kinda pricey for a simple relay.
Ah I see you found a relay that's not overpriced. Thanks again bud✌️
@@scarygary3569 Your welcome. Now I haven't load-tested the relay yet so I'm not 100% recommending it.
@@Roll2Videos gotcha.I also need to check and see I'd the shunt I've got actually cuts off on low temp.Ive seen many products say they have the low temp cut off but when put to the test they don't work out.Still be nice to have the other protections active tho.
Hi, what function does the ssr-40dd do? do you need the ssr-40dd for low temp cut off? I see the output says 24 v + so as I have a 12v, Id have to get a 12v output if I cant use the low temp cut off on the 2 phase switch? like your videos, cheers :)
You can use any relay you'd like. Just size it appropriately
will the cold cut off protection work without a relay?
@@rustytoronto No, you will need a relay for it to work.
Thanks brother, Maybe other people might find this helpful too, cheers :)
Hi, I’ve just watched your video, you seem to know this piece of kit very well, I’ve just installed this shunt on my 12v camper setup, however it doesn’t pick up the solar charging, all my negatives go to a negative buzz bar, can’t you help me fix this please?
Is the solar connected to the proper side of the shunt?
The solar is connected to the buzz bar which is in front of the shunt, but my shore charger is also connected to the buzz bar but is can see the shore charging, very confused
@johnwilson1620 Is there enough solar to be seen? Is it being used up by an inverter?
@@Roll2Videos my shunt model is KG140F I’ve not had the inverter running as I’m on shore power for my appliances but was testing the solar, that’s how I can see I have that issue
@johnwilson1620 Clamp meter
Hello its possible to install this shunt in liciti battery box to the battery im confused abit bcuz in discription says its 120v 100A do i need higher then 120v for eu use
There might be enough room, but I'm not optimistic about that
Is this the 400a or the 600a model ?
The one in the video is the 600A, which is overkill. Could you imagine the size conductor to push 600A?
