Installing the JK-BMS in a Seplos MASON DIY Box? Well, it's not that easy... but here is how!

Hi MrTutkun. Is it possible to get the 3D design for JK BMS inverter communication board?

[@BrindleBrown]

Without further to do, I must say that this channel is awesome! I was just watching another channel (gridbusters) and I noticed just how much of what she is doing was due to the lessons she learned from watching your channel. She has a pink heat gun too! It must be so fulfilling to know that you are inspiring an international community of solar power enthusiasts. Keep up the great work!

[@OffGridGarageAustralia]

Thanks a lot for your kind words and feedback!

[@ElectronTinkerer]

What a great project. Very well executed. The reason for all the effort eludes me a little, but it was certainly entertaining. I love DIY stuff.❤

[@CollinBaillie]

The reason, was simply to upgrade the BMS, which meant the modifications were necessary to fit the new JK inverter BMS in a box which wasn't designed for it.

[@OffGridGarageAustralia]

The 'old' 10C BMS goes to a friend in Germany, so the box needed a new BMS. And why not use a JK, right?😄

[@tiborchren]

Great video, I have been waiting for these videos since it was first mentioned about the new JK Inverter BMS. Try using threaded inserts in the 3D printed frames holes that are pressed into the plastic with hot solder. 3D print the test holes that will best fit your purchased threaded inserts. Self-tapping screws are fine for the prototype, but try threaded inserts as upgrade for the final version.

[@madvlad1]

Yes! Brass threaded inserts are excellent and would make this solution truly #bombenfest!

[@OffGridGarageAustralia]

Yeah, I've seen them. I thought they get super glued into the 3D part not pushed in with a solder? I used normal M3/M4 screws and the result is actually very very good. I'm surprised myself.

[@marekc8654]

I understand that you've had all that fun 3D printing. For those without 3D printer you can alreasldy buy just front plates for JK inverter BMS with 4.3inch display cutout or whole case. They are fairly cheap now on Ali.

Great video as always Andy! I bought 6 Mason 135Ah almost 2 years ago, they came with the V1 BMS, 48100 10C, and must say I'm quite disappointed with their reliability because I had 2 of them die recently, one month of interval between, and am afraid the others won't take much longer until it happens. Seplos provided me with instructions on how to replace a diode (D4) so I sent to a technician who did and it worked, the BMS is back working, but it's a big hassle. If I have one more dying soon think I'll replace them all by JK as you show here.

Moin Andy, great design and work. I think you use PLA for the prints? What happens if the JK gets warmer than 60°C? I think you need something more heat resistant to hold the JK in place.

[@OffGridGarageAustralia]

Yes, I use PLA+ for printing. Should not be an issue. The BMS will not get that warm. There is enough airflow.

[@sjdtmv]

Great mod there Andy, a lot of work and measuring going on, as a Boily I would have made a whole new front plate that would allow more room, but a lot more filing needed for the comms PCB, I do like the looks of the 3D comms PCB saves a lot of drilling and filing on metal

Hi Andy, I have just brought a 3.2inch JK screen, the wire that connects to the BMS, has the same connection on both ends?, doesn't fit on the BMS end, can you tell me where I can get one that fits? Nice video, I was thinking of doing the same with a QSO battery, the day before you brought out this video.

[@OffGridGarageAustralia]

Is the 3.2" screen compatible with your JK BMS? The cable has two different plugs normally. The tiny one for the BMS and the larger one for the screen. Yeah, the QSO batterie is on my list as well. That's even more complicated though...

[@paulg1802]

Same problem I had with Apexium case. modified by covering communication board holes and cutting new holes. Printed the new communication board shape with scale 1:1 on paper and stuck on where to cut. Used small M3 screws with two nuts as stand off.

[@videoflieger1239]

Another big JK Inverter firmware BUG??? Hi Andy, did you test a JK Inverter BMS as a master and one (ore more) slaves connected with RS485 to the master? In my Victron-System I got via CAN only max/min cell-voltages and temps from the master BMS and no volt/temps from any slaves as max/min from the whole battery-system (all packs). The cell-block-count, capacity and all other values are reported correct to victron. I updated the JK firmware to the newest 14.20 but this BUG still exists. Do you (or any other user) have this problem too?

[@rockyfox7087]

It still has a lot of issues and jk support doesn’t actually care For example the SOC is not related to total voltage so you will have different soc with same voltage Besides it sucks with other inverters like the Growatt and Sofar

[@OffGridGarageAustralia]

Yes, I heard about this bug and tested it. No such issue here. Master still showed the slave after two weeks...

[@rockyfox7087]

@@OffGridGarageAustralia its not that it doesnt show the slave You got me wrong What I meant is that im having different SOC with the same voltage in the same battery, so in one day Im getting 50% for about 51.xx and other days its 50% for 50 volts or even 48 So I think its because the SOC now is depending one single cell voltage when any cell reaches the “SOC 100%” value in the settings then after that it doesn’t really change according to the total voltage

[@vladislavlozitskyi671]

Hello! I have a Deye SUN-6K-SG03LP1-EU in pair with the JK BMS PB2A16S20P (HW V15.XA, SW V15.17), I successfully installed it and it works very well. I have only one problem that I can not fix for now - I need when Grid AC is lost or restored (no matter) to force the battery to charge to RCV (Requested Charge Voltage - 3.45V, 55.2V) but it charges only to RFV (Requested Float Voltage - 3.35V, 53.6V). When AC is restored, the only solution for now is to turn off and then turn on the option "Floating Current Voltage" in the BMS. After that, I see that the charging voltage is set to 55.2V and when the charge is finished the voltage is changed to 53.6V. For now, this charge algorithm works only by timers set in BMS. Is there any way to force the BMS to request RCV on AC restore (any trigger maybe)? May be someone know how to fix that? I've talked to DEYE support and they said that this have to be done on BMS side. Thank You!

[@Shellyfi]

Nice work. You should use heat inserts for screws

[@OffGridGarageAustralia]

Very good job Andy. Looking at your video, I've had an idea. Instead of drilling, cutting and modifying the front plate of the Mason Seplos, why not create a plastic front plate with 3d print, designed for the JK BMS and all the relative components? Best regards!

[@OffGridGarageAustralia]

Yes, that would be another alternative. Printing a whole new front panel...

[@panosbalakGREECE]

We love Andy❤ greadings from Greece

[@the_amazing_raisin]

Would it be easier to surface mount the 3D printed adaptor for the communication ports on the outside of the case? You could cover the existing cut out for the ports and maybe make a cut out for the wiring Same for the display, make an adaptor that sits over the existing cut out and you get the bigger display if you want

[@OffGridGarageAustralia]

That may work with the bigger frontpanel of the larger 280Ah Mason box. This here is very tight and not much room to move things around.

[@Knightliner69]

Looks a bit rough indeed but hey it’s a prototype 😅. For the final solution I would just use a new sheet of 2mm aluminum and some L-profile to form the lip at the edges and paint it black… e voila… you have a case looking like from the factory! Happy you found your way in 3D printing. It’s a great tool to make all kind of stuff. Just keep in mind to use the right filament especially if the part is used in an environment where it gets warm or even hot. we wouldn’t like to see that the BMS is falling off in your next hard discharge test…😂 Just kidding! Cheers Jens

I can print a new frontpanel out of 2 or 3 pieces... Yeah, heat could be a problem with this PLA but the BMS will not get that hot.

Then the charging current on inverter is 80A(command from bms) and the inverter don't allow me change a charging current(on inverter) because BMS send a command to it. In the ideal situation, both battery will be charged 40A on each unit. But the real situation that I face sometime. The first battery is charged 45A and second battery is charged 35A. Then the first bms is turn off charging port via " over charge current protection". I think Jkbms should have separate "Over charge current parameter". Please suggest me.

I smell 100K anyone isle?

[@jashast3248]

Wow! Your 3D printer is pretty expensive. You would have been better off getting a creality K1C or K1 Max. They are almost the same price but have way more features and more than 10 times the printing speed. I got my K1C a few weeks ago and it would print one of those big brackets in around 45 to 60 minutes They can even print high temperature filament like nylon and support carbon fiber filaments

[@OffGridGarageAustralia]

I don't know what that means.

[@jo8ephthomas]

You can solve most problems with a jk

[@OffGridGarageAustralia]

Hahaha, yes, that is actually true!
