In another test, I have connected the JK Inverter BMS to the Victron Venus OS and found that it does not show the consumption correctly. To find out more, I temporarily replaced the battery shelf with the Tower of Power and even let the JK BMS control my whole production system. After several hours of testing, I can still not find out if this is a problem with Victron or the JK BMS.
I have run the same test with the Seplos BMS V1 and V2 and also the Peter boards and it works without issues. All other BMS have failed so far to show the correct data...
JK Inverter BMS and JK 'Old Style' BMS. Both are pretty pretty good!

Hi Andy. First time long time. I'm running 3 JK "inverter" BMS's. (200a). 1 multiplus 2, 3 victron smart solar mppt 150/100. All connected to a cerbo gx with "has dc" active. I show normal consumption independent of solar. I do have the JK bms controlling charge voltage but not current. This way the mppt will push as much current as load demands. I believe if you set controle current the mppt will only push what ever current your bms will demand. Hope this helps. Keep up the awesome productions. Thanks to you and all the information you provide I was able to setup a nice system at my house to offset my power bill.

Hi Andy, you have several brands of bms and each one shows what it wants since there is no standard, I know that you are determined to know everything since you are worried about how each cell works but you will not be able to do anything with this since you cannot controlling how each battery is charged by the varied parallels that you have there, even if you use the same brand of BMS you are not going to achieve it, not even the Tesla you drive knows what happens in its 7000 cells, you know it and so do we.

Yeah, 1 June was pretty crummy solar weather here in Nthn NSW too. But it's been sunny ever since. :) I wonder about all these extra Victron systems and BMS comms, Peter boards etc - it seems overly and unnecessarily complex and expensive for what seems to be little gain. It's great you get into the weeds but so much $$$ for this stuff - I'm just not seeing the value for a DIY set up. I have Home Assistant, a smart shunt, server rack batteries (with PACE BMS), a big lead acid bank for backup, and an 8 kW *non*-Victron inverter/charge controller which works with Solar Assistant and Home Assistant. It's pretty much plug and play and at a fraction of the cost. I honestly don't care that much about the BMS provided it does its job, i.e. to protect the batteries from bad things, along with the fuses/breakers. I get all the data for monitoring/alerts as required but otherwise the fact they are a PACE BMS makes little difference to the performance of my system. Perhaps you can expand on the value/usefulness of all this extra complexity and cost?

@tyweb9264 11 дней назад

Hi Andy, Another great Video. I am NOT having the same issue. I have AC coupled Solar and DC coupled Solar, 3 out of the 4 batteries are using JK BMS, reporting to Victron through Can bus, I also Have a Vic Smart shunt that they all go through. I endabled DC system about 36hours ago and I am not getting the same issue, unitil my batteries become full, at which point the 2 x Fronius (AC coupled Solars) are backed off and the DC solar are shut off, or throttled to match the actual AC load.

@beebop9808 15 дней назад

Agree yes. Data maps are different for different devices and on different comm protocols. JK pretty much talks on all protocols. Match the protocol with the BMS and choose the BMS brand on the Victron. First guess, have the JK emulate the Seplos on whatever protocol it uses. Hopefully hit it first crack and not have to hunt and peck all might long. Cost too much beer. hahaha

@junkerzn7312 15 дней назад

The CAN protocols are basically communicating with formatted binary fields (well, actually a mix of ascii and binary). Parameters are typically just a number, not a descriptive text. Values have unspecified precision (e.g. does the value 100 mean 100, 10.0, or 1.00 ?). Data fields may contain a descriptive text, such as for alarm messages, but typically use binary representations for values. On top of that, there are often piles of edge cases where the data does not behave as expected under various abnormal conditions. The only reason it works at all is because the various vendors copy each other's protocols... but they do it by observation rather than by definition. So basically its a big Potpouri. Which is why I don't trust cross-vendor CAN compatibility. At all. For anything beyond user display purposes. Certainly not for control loops. -Matt

@NaamNatuurlijkniet 14 дней назад

Hi, Andy.. another great video. I am wondering though. Victron also has the possibility to actually measure DC loads with a Victron Smartshunt set to do just that. That way Victron may not need to calculate the DC load , but actually measures it. I guess the “has DC Load” Switch is just there for the correct calculation of the load. Perhaps you could try and see if it makes a difference. Should be easy to do by just telling the shunt it is a DC meter. One other answer here is smart also, when asking “peter” to monitor the Can bus he might be able to filter out the problem. When it is easy to fix by either parties perhaps one of them wants to do so. Since the JK is getting more and more popular and more cases are hitting the market with the JK integrated it is of importance to both companies to make this work. Let me know what you think.

10 дней назад

That 100 amp rating is the BMS controllers in and out maximum so as long as you do not charge or discharge higher than that you should have no problems.. I would suggest that you install a fuse or breaker that could disconnect the battery from the BMS/load in case of a short that might try and draw the full amp potential of the battery pack.. The BMS should disconnect at the level you set but two is one and 1 is none is a rule I live by..

I'm trying to understand the "Max Charge Cur (A)" parameter, it's functionality, etc. Does setting this parameter control the charge current through the BMS, say if I set it to 10A?

10 дней назад

@@webejamn2 I am pretty sure that a BMS is just a safety device and does not actually regulate charge or discharge so it should disconnect if a parameter that is set is exceeded.. I also believe you can set the delay for the tripping and reset where it connects again and then repeats that time cycle if the fault still exists.. It would be up to you to set the charge device to limit the output as my Outback 80 amp solar charge controllers and 8kw inverter are where I set these output and input limits and they have regulation abilities to reduce the amps.. This is my opinion so seek more to validate it..

@TheRonskiman 15 дней назад

I have an AC connected inverter, when I first powered up my system the energy meter was connected to the Cerbo, and it could see the power produced via the AC connected inverter, but consumption was always the same like yours was, the Quattro wasnt actually connected to AC at that time just the batteries, so it was assuming all the AC connected solar power was consumed. Once the Quattro was placed in the grid feed it has always shown consumption even with DC system shown, as it can see what's coming from or going to the grid, and solar, and batteries via the shunt. My batteries BMS is not connected to the Victron system. My guess is something isn't being reported correctly, and that's affecting the calculation.

@sirmonsterle 13 дней назад

I have another problem with my off-grid system. I have the battery bank with the old JK BMS connected with dbus-serial driver to the Victron system. When I have an AC load and the sun is shining at the same time and there are only small currents going in or coming of the battery. The Victron system will then show a current of zero. When I then stop the load the current is showing again. Or when the sun goes behind a cloud then I see the higher current again. Very strange. Last week I added another battery bank in parallel. At the moment the RS484 converter is still missing so I could not connect the second BMS. But I'm afraid, now when the currents to the batteries are only half of what they were, the problem will be more often. The strange thing is, that even the JK BMS app shows no current then. So I use the smart shunt as battery monitor. But the problem is that when the BMS thinks, the battery is full, it reduces the current in the MPPT even if it has not reached the SOC to do that. So I loose some sun for the batteries. Maybe I should look if I can only use the cell voltages for the calculation to reduce the current and not the SOC any more. I think none of the BMSes are good to measure small currents

@millzee60 15 дней назад

I have DC power switched on because I'm on a boat with a lot of DC devices. Without a dedicated shunt the DC Power is calculated rather than measured directly. I added another smart shunt and configured it for DC power and now the DC Power on the Color GX is as measured. The consumption on mine includes the power used for AC loads and for charging the batteries. I also read something like the BMS has to report the power, not just volts and amps, in order for the consumption to work. But I read it a long time ago so I'm far from 100% on that. That said, I have a Batrium BMS and it is deficient somehow so on the Color GX I use the Victron BMV as the battery monitor but the Batrium still sets charge current and voltage limits.

@OffGridGarageAustralia 15 дней назад

Yes, it will probably work with a second smart shunt. That would mean though, I would need to separate all DC loads from the main busbar system run them through the shunt and create a sub busbar. That's not going to happen in my battery shelf due to lack of space.

@millzee60 15 дней назад

@@OffGridGarageAustralia It wasn't the addition of the dedicated shunt that fixed the consumption problem, it was the use of the BMV as the battery monitor rather than using the Batrium BMS.

Hi Andy, don't bother trying to integrate all that information into your Victron system, each brand does it in its own way, it is difficult and the data is not correct in many cases, I get a BMS when programming it through the app The values that I gave to the BMS were not executed no matter how much I wanted them to and BMS said that everything was going well, the BMS did what he wanted, that is, what it already had from the factory. If I told it to cut the charge at 3.6v, it would do it. at 3.4v and I was able to verify it by measuring the cells directly, so don't believe 100% that the data you get from your BMS is real.

@gavinb4497 15 дней назад

As you stated the CanBus protocol is not compatible

is there is any way to add an inverter directly connected to the battery to the measurement system? currently my dc load (inverter) is not counted by the victron system and the jkbms is lazy to measure low load. It would be nice to have an DC Meter ...

@OffGridGarageAustralia 15 дней назад

If you turn on has DC system, it should work. That's how I do it with my second non-Victron inverter. The DC Load will show the consumption of this 2nd inverter.

Hi Andy, i got firmware V15.24 from JK, if you want it let me know ho to get it to you

Where to get? Any release notes?

Maybe bcs JK reports charging as positiv and discharging as negative power?

@windsine 15 дней назад

I think JK reports batt current as a signed int32 (+ and - values). Maybe see what format the seplos BMS reports as?

Like# 187 - My Channel is getting better! Remind us what your system voltage is again, 48v?

@taj-ma-haul9094 15 дней назад

data alignment, some BMSs follow what Victron follows, the others don't. Not sure what data protocol any of them use/follow, but that seems to be the issue in my mind. I bet the Peter board dude could shed light on the data standards!

If the Peter Boards work, please ask Peter (the developer), he'll be able to explain the difference. ie what he does to the raw JK data to make it work

@diyEVguy 15 дней назад

Good idea.

I have decoded the original JK protocol to be read by an ESP32 (similar to Peter board). But, when I started investigating the new JK Inverter BMS communication, it's a lot different than the original. Still working on it, but I need to purchase a new JK inverter board "to spy on it"!. I can't say yet whether the new protocol is an extension of the old one (thus would partially work with Victron), or a new re-write. Initial observation leads me to believe it's a new re-write, but I need to do some more tinkering...

Here we go... Tower of Power = ToP . Let's call it "ToP" for simplicity's sake.

@fibranijevidra 8 дней назад

Why would anyone buy JK BMS after their recent very dangerous fault? No word of that?! I am not even considering JK anymore, but a word about JK version used in this nice box would be fair. Is that already forgotten?

@astrogerard 15 дней назад

Even with an external energy meter and a extra PV-inverter on AC-OUT the VRM Portal totally goes banana's. The current values are always right, the graph in the system overview is way, way off and the shown data makes no sense at all.

@blieven1 15 дней назад

Indeed noticed the same with the overview graph, advanced view is correct though. Planning to install an extra grid meter hoping to have a better overview in the future
