Well, I don't know what to say, but the longer I look into this BMS the more weird functions I find. The software design is not great and has some unintuitive functions which don't make sense to me at all.
I mean, the BMS needs to trip with overvoltage protection just to reset to 100% SOC? What would be the purpose of such a design?
I have all the information about how to reset both, the 10C and 10E BMS, at the end of the video and will also share this on my website here. off-grid-garage.com/my-settings/

I am also happy to see a new video from Andy every time and I also learn a lot, thanks to you Andy. I have had good experience with seplos support and they always try to help. | I have had other inverters and other Support contacts that were not helpful and sometimes it took 2 weeks to respond. So for me the support from Victron and also seplos is great. Mistakes happen by people in real life and the way the support handle it brings success or fail. Here in Germany it is not a good solar weather in the moment, but the spring and summer will come and all I have learnd here by Andy will will bring success.

Another valuable contribution for anyone with a Seplos BMS. My inner code geek says that I will never purchase one due to the sloppy programming and obvious "we didn't test in real life" nature of the software. But you really went above and beyond to test settings and experiment to find information that is entirely not obvious or intuitive.

Thanks a lot John, I appreciate your comment. Sometimes the Seplos engineers don't know what single functions are for and how they work with the battery, so, yeah, obviously not really tested and understood.

Hi Andy. Great video's and as a fairly recent Solar fanatic - great to see the experiments!! I have 2 X generic Chinese LifePo4 48v 16 Cell 155AH Batteries and did a stress test to check the capacity which came out spot on. The only issue is that horrible SOC issue but mine isn't 1 or 2% it's 10% cumulative unless I cause a Cell OV to 3.65 volts, which like the Seplos recalibrates my Batteries to 100% SOC. It's a Daren High Tech BMS which a German Forum describes as a Seplos running different software but I'm not convinced by that. These Battery games are sometimes fun but often frustrating. Your videos and viewers comments help cut time and hopefully save people money.

@@OffGridGarageAustralia Seplos “Oh Boy” like you titled once. It’s EEL also on my side. I will use the Lynx Distributors from Victron, but I left out the shunt since I thought the Seplos can handle all that. I think you have one in, but what I understand it is not used. Is it feasible to let the Lynx shunt talk to the MPPT and leave the Seplos CAN just disconnected ? Of course that feels like a waste and would not be done when spec’ing a system from the beginning. But maybe it could be a workaround if like in my case the Seplos is already there. And well I like tinkering anyway…. I am just at the start of the journey.

Thank you for these videos! Been having a problem with my Seplos BMS. The SOC keeps suddenly changing from 50% to 100% or 0%, I believe it's because the high current (100A) either discharging or charging and the cells not being balanced correctly because of the poop inbuilt balancer then causing the SOC to be reset by the monomer voltage alarms. Looking at getting an active balancer to sort it out, the NEEY looks pretty impressive so might have to get that. I'm currently charging the battery at 50A and seems to be much happier and just about to start balancing at 3.450v.

Hello Andy, Another super great video from you. I use 2 packs from Seplos with the 10c BMS but firmware 2.9. I have experienced a different behaviour of the pack here. It's not as severe as yours, but I think it's really the firmware, because I use the following settings here. My alarm voltage is at 56V, which is where it should switch off. Warning is at 55.2V for me. We also discuss the Seplos BMS here in the German community and have really noticed a difference in the behaviour of the BMS with a different firmware. The 2.8 really brings the problem you describe. The 2.9 is significantly better. I have even noticed that at around 94%, the BMS regulates down to 10A charging power. Unfortunately, the total charging power and not 10A per pack. That's why the voltages crash again. Since I can't provide any pictures here, I'll send you an email with a few photos and also with an excerpt from my monitoring, where you can see interesting things. My MPII even went into absorption, but not for long. But it seems to work with the 10c and the 2.9 firmware version. I'll send you everything by email. Unfortunately, today is Saturday and PV washing day. So it's raining, so I can't continue my test here at the moment. I don't have the power. Today there are only 1164W from the roof. Until your next video. I look forward to your proposed solution. I assume that's where the shunt will come into play. Oh, the SOC is also calculated according to the ampere hours and not according to the voltage. However, this also seems to be a firmware issue. Greetings from cool, wet and windy Germany. Sven

Hi Andy... I'm writing too from germany and here we try to get run the Seplos FW 2.9. I have seen, that you are running still the 2.8. Could you explain, why you do not update to the next FW revision? I have 5x the 10c. I hope that in 3-4 weeks i can get them assembled and connected to the cerboGX. The first battery I have already flashed to the 2.9 and it seems to run "ok"... but the weather is bad... so the battery has never seen mor than 65% SOC. Stay tuned.

Thanks for sharing these valuable information. That's great and the BMS seems to be acting differently. I haven't upgrade to 2.9 yet, because Seplos told me there would be no new features in terms of the comms with Victron. That was actually all included in the 2.8FW. I'm also not a big fan of the BMS slowing the charging down to 10A at 94%. I know they do that to be gentle on the battery but I think this is not necessary as we charge to only 3.45V anyway and let it absorb from there. I have turned this feature off.

Hi Andy, I can confirm your observation. I use a Seplos BMS version E together with a Goodwe Hybrid Inverter. Unlike the Victron, the Goodwe does not allow you to set any relevant parameters for charging. The inverter needs Can-Bus communication with the BMS. Everything is controled by the BMS. I have set the Total pressure high pressure alarm to 55.2V and Total Voltage overvoltage Protection to 55.5V. Whenever 55.5V is reached, this is my 100% state of charge. So far this has worked. The Goodwe then terminates the charging process. Since there is no float mode, the voltage drops quite quickly. The balancer has hardly any time left for work. The pack does not stay in the range where the voltage differences are high enough. I cannot complain about microcycling, as the Goodwe only starts charging again when the charge level falls below 96% (to be set in the Interval charge capacety parameter). Greetings Andreas from Cloudy Germany
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
Hi Andreas, thanks for sharing. So your BMS only resets to 100% at 55.5V that also means it disconnects the charger at this point. There is a setting to enable this 96%SOC feature. I think I turned this off right at the beginning, but yeah, this will prevent micro cycling.
@andreasreder9560
@andreasreder9560 Год назад
Hi Andy, I would confirm your statement for the 10-E that it jumps to 100% in an overvoltage situation, and this is either the pack voltage or the cell voltage. From my observation, the "Total Voltage overvoltage Protection" value ist triggert, which I have set to 55.5V, but can also be set to any other higher or lower value. Unfortunately, there is no sun in sight in the next few days to be able to observe anything myself. Viele Grüße Andreas

Hello, I have a GW5048-EM. In the BMS I have set the CAN protocol to Pylontec and in the inverter I have found that it does not matter which battery type you choose. I have chosen a Tecloman Firefly. You can also set a self defined battery type which allows you to set more charging parameters in the inverter, but CAN is disabled in this setting and it always shows me 0% SOC and the battery does not charge. I have also not tested this setting. In forums you can read about people who manage this setting to work.

With my setup I use the Inverter software charging voltage set to 55v, and the 2 Seplos packs I use Mason 206Ah 51v, which at the start were not matching at 100%. This was because I failed to charge and discharge the first pack properly when I assembled them. But now after 90 cycles where the pack difference was as much as 5% out I decided to bring the voltage up again to 56v to get to 100%. Now They are in sync with about 2.000ma difference, whereas before it was 150.000ma. But if I take my car a Nissan Leaf were I monitor the BMS using the Leaf Spy then 100% the same issue is seen here! SoH was when I bought the car second hand 83% and it dropped down to just over 80% after 50k miles, but when I used the DC chargers on long trips, its normally charged on a AC 7kw, the SoH jumps back up to 83%. The car will always display 100% no matter what to the user once fully charged, but give it an hour and you can get some more in. So I am not sure what your trying to prove here. Unfortunately my Inverter failed yesterday and the DC side has short circuited. Now ordering a new Inverter could be many weeks before i get back up and running.

Hey Andy, as always, great work testing. I found out another really annoying thing the other day with Seplos. So if you are running multiple 200A models(or any of their models I guess) in parallel, the charge and discharge voltage communicated to the inverter(CCL command) will be set at half the rated power of the BMS, so 100A and the ONLY way to change this is to change the overcurrent warning and protection to something higher, to match what you want to set as a max, as it's tied to whatever the warning is set to(exactly 50% of this) and you can't change the warning parameter without also changing the protection parameter, in turn invalidating the BMS own defence for overcurrent. If this isn't bad design, then I don't know what is, horrible. My 280Ah cells are now only able to run at almost 0.3C. Seplos doesn't see an issue with this.

@leet3707 11 месяцев назад
Daniel- just had this curiosity here. I'm using a 10c originally and was 200amp discharge. Since added a second 10e BMS and Inverter holds max discharge at 100amp as you say. Then connected in parallel, max discharge of both packs now showing discharge at 200amp max and 380amp charge. Inverter max is 100amp but adding additional Inverters could become a problem. A 200amp BMS restricted to 100amp, is it really 200amp? As it stands, the only way I can see around it is locate another 10c and add Bluetooth screens to both and bin the 10e.

Andy, You sure manage to pick out my pet peeves... As the owner of several Daly's I am used to this BS. They only way to reset is using HVD. If you like to use 3.45V absorption (55.2V) I only get a HVD if my battery is out of balance. If it is in balance I need to crank the voltage up to get HVD (3.65V). Sigh. Now one way to force it is just to lower the HVD voltage temporarily in app, but that is a duct tape solution. Still looking for a better solution. For implementation on BMS a Victron type solution is probably too complicated. However, to implement the solution as seen here with 56V may actually make sense: If you hit 56V and the current drops a bit (i.e. you are absorbing), then reset. Also provide a field in app to set that 56V. For the Seplos is the 56V hardcoded? I.e is it always 56V, independent of other settings?

Hi Andy Hi everybody I'm a great fan of your work as "Professor Off-Grid", teaching in an open source and collaborative way. As probably anyone in our circle, we are suffering from proprietary, closed source hardware lacking the possibilities to integrate as we desire. As hardware is the new software, a BMS, containing a processor and lots of software on my opinion should be open. And open source ! Why don't we gather resources ( corowd-sourcing ) and define and produce our own BMS the way we! want it to be ? A Open-BMS fitting our needs, instead of buying cheap stuff we can't even fix, because we have no deep documentation what's going on. - If you can't open it, you don't own it :-) Who's in ? let me know ;-) greetings from cloudy and cold Switzerland heading spring Christoph

Hi Andy, this is what I’m finding also. This is fine if you can set your inverter to charge to just below the OVP however, most inverters let the battery decide what voltage to charge to and there is no target voltage on the Seplos BMS. My question is this; once the Seplos has learned it’s high SoC which triggers the OVP does it then count amps out vs amps in and just allow a charge to just below the OVP? Reason I ask is because I am trying this with a Sunsynk inverter. The first night we got both pack and cell OVP, next night just the Cell OVP. Next night. Nothing. Seems to be running well now. Is the Seplos that smart that it just uses it’s shunt to look at SoC?

@TYPE xxi - WOLF yes absolutely, it's a 3kw inverter with 2kw of solar panel as an emergency system and I manage the protection from the inverter. I found that the communication between the Seplos and the Growatt a key factor since the inverter is also connected to the power of the grid . On a cloudy week with the battery bank depleted the inverter kiks in without interruption.

You have spent a lot of time on this Sepols BMS and sort of wondering why. Is there something you thought you would initially like regarding this BMS over either the JK or JBD/Overkill? Honestly, I have been quite happy with my Overkill BMS and have received very good customer service when needed. I don't really see a need to change. I did buy a JK when you were experimenting with them but have not gotten around to hooking up a battery pack to it yet. The Overkill just seems to do the job. Yes, it has a rather small passive balancer but my cells seem to stay rather balanced quite nicely on their own (of course I top balanced prior to putting them into service). So, was there a reason you chose to devote a lot of time to experimenting with this BMS or was the reason just curiosity? About the SOC reported by the BMS. Actually, I don't pay much attention to it because I think the Smart Shunt is more precise. The two rarely agree anyway. I rely on the Smart Shunt for SOC.

Thanks John, yes, in deed, I spent a lot of time in my garage wondering who came up with such weird software design. The main reason for doing this is, that people wanted me to test this BMS for a long time and I always looked at it and wondered what's so special...? The great communication features were always highlighted to me. After all my testing, I must say, this is one of the weakest feature of the BMS together with the software design and features. Yep, I agree, the smart shunt is the way to go in terms of measuring SOC the most accurate. I can see this daily in my battery shelf.

Hi Andy and thanks again for sharing this video. Indeed when you reach , the over voltage pack (OVP) or over voltage Cell (OVC) the BMS, sets the percentage to 100%. But with the right settings, in floating charge, your BMS continues to charge at very low current, and it reaches 100% without being over voltage. With these BMS It is the stand by(idle) that must be reached and not exceeded. With the right settings you can do it. Very important ! Andy, on this subject it is with the discharge that there is big problem!! I haven't been able to solve yet. Example your battery is deeply discharged let's assume that there is 20 or 25% capacity left, And yes! one cell, only one! reaches the UVP your BMS goes to 00%!!(yet there was 20-25% left?!!) Then when you recharge your percentage is completely wrong!? he's going to miss that 20 or 25 ABILITY?! and there it will be necessary to reach the OVP or OVC so that it indicates 100% again Normally you can adjust your percentage with the Software (PC) concerning my BMS similar to the Seplos, you go to Configuration Settings /read capacity /you write your new capacity (corresponding to 100%) confirm Write, and automatically your BMS will go to 100%.

Hi Andy, I have a JK BMS and it sets SoC to 100% when Cell OPV is triggered. If we decide not to exceed 3.45V when charging then Cell OPV should be set to 3.45V. Same for SoC to 0% with Cell UPV set to 2.55V. By doing so SoC is always accurate and we don't need to overcharge the cells to 3.65V which is bad on the long term. Hope it helps cheers Yann

@@OffGridGarageAustralia Hi again Andy, who can the less can the most: if BMS OVP is lower than 3,65 it will work in case of charger failure. Also, it is more consistent to set OVP to the maximum charge voltage that you want to see for one cell. My system is setup like that and my SoC is always accurate without having to charge the cells to 3,65V and stress the battery. Regardless of this disagreement, congratulation for your fantastic work.

Thanks for sharing, Patrick. I would not be too worried to keep the batteries at 90%SOC only. You can safely charge to 100% if the voltage is not going too high. So, keeping them 3.4/3.4V won't stress them. and with some absorption time, they will reach very close to 100%. The LFP Teslas can go to 100% every single time. That's almost recommended to top balance and also reset the BMS to 100%

Sobald der Strom dann auf ca. 0A abfällt setzt sich der SOC auf 100%. Das klappt soweit alles gut. Bei mir ist eher das Problem, dass das BMS driftet. Das heißt wenn ich mehrere Tage lang den Akku nicht voll bekomme, wird der Akku immer leerer obwohl der SOC zum Beispiel noch bei 15% steht bei welchem der SI sich in Standby Schaltet. Laut Berichten im Akkudoktor Forum sollte sich beim erreichen vom unteren Alarmwert der SOC auf 7% kalibrieren. Passiert bei mir aber nicht.

Agree, having to trip overvoltage limit to reset Columb counter is stupid. Have you figured out what criteria JK BMS uses to reset Columb counter? A simple voltage trigger is the most practical, even though not necessarily giving 100% SoC accuracy. You don't want to make Columb counter reset too restrictive and tough to satisfy. Better to error on resetting a little less than 100% SoC then going for months without a Columb counter reset. Adjust battery capacity setting a little less than actual to avoid over discharging battery by % remaining indication to cover cases when Columb counter got reset before true 100% SoC. BMS's multiple parallel chip resistors for current shunt is not very accurate for current measurements across low to high current and temperature variation. This limits BMS SoC Columb counting accuracy making periodic Columb counter full resetting even more important.
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
Apparently the JK uses the OVP as well and resets at 3.65V only. I never paid attention to that cause I'm using the smart shunt. I really like the shunt and parameters we can set to reset to 100%. This can be really fine tuned and will work with almost any setup.

@@OffGridGarageAustralia I assumed they were using a percentage of cell overvoltage limit setting. You can try to adjust it and see if Columb counter reset voltage changes. May be based on individual cells' voltage which makes Columb counter reset dependent on cell balancing.

i need a valid reliable solution cause the drift is annoying and the system unreliable but SEPLOS does not really help. They simply ignore customer requests for products sold. They only do care in pre sales and work on new products , a mess of new products all suffering the same mistakes cause now they are starting to sell powerwalls while the current bms is not running properly. Always tiny issues and if one is solved the next will come up. The balancing has also never been solved cause it does only work with a neey balancer even with brand new EVE LF280K cells from the manufacturer. It is not a question of grade that causes those drifts. Sad but true. Still wonder if I should leave the seplos ship and move ahead to the diy bms from stuart pittaway cause that is achieving so much more with an even better forum support. They have added canbus support and seem to support victron and hopefuly the growatt and other inverter too. in 1 year they will have fixed that or I will start to replace the first seplos bms. Hope they listen to you more and start a program like neey had done to achieve a better customer satisfaction.

Thanks for sharing. Before you move on, just wait for a while until I get the new BMS. If they hold what the company promises, this could be it. The SOC reset is really annoying and can only be overcome by tripping the BMS in OVP or setting it manually (No. 59, what someone said here).

Something crazy is happening to my Bluetooth Samsung buds. I only get you on loud. When I turn you to off, you are still talking very strange.

Hej alle sammen Jeg har Seplos BMS 200 ah. og JK. B2A24S20P 200 Ah alle lukker for opladningen ved 56,00volt alle BMS lukker hurtigere ved kraftigt opladning da batteriet løber fra opladningen. efter lyser variabel opladning. Måske skal vi prøve at flytte kalibreringen til minus siden !!! forslag Henrik
