I have now disconnected the Gobelpower BMS from the Frankenstein battery. For the last 4 weeks, I could thoroughly test this BMS and have found some interesting points. I will share my thoughts about the #Gobelpower #BMS, the good and not so good, what other BMS do better and where the Gobel BMS shines.
Here is my final #verdict.
The Gobelpower is really one of the best BMS, I have tested so far.

We are in a very interesting time with residential power storage. It's like early pioneering times. These companies build all these great hybrid inverters and BMSs etc without really knowing what they are doing, or really understanding all the challenges. Remind of the the PC days back in the late 80s and early 90s, just when things started to heat up. We have exciting times ahead with all this solar related tech.

Hey Andy, already left you couple off comments on some other video about this, I never use total voltage protection on any of my BMSes when single cell voltage protection is available, just disable the switch in the Seplos BMS set the overvoltage to 55V or 54.4V or 54.8, now when the overvoltage is triggered, it doesn't disconnect charging & battery is reset to 100%, if cells are somewhat balanced this means its actually 100%, the only issue is there is no separate floating voltage option with time limit. & since a battery with well balanced cells will drop current gradually allowing it to absorb for a longer time before reaching the actual "overvoltage protection value" I compensate for the floating absence by lowering the "charge over voltage protection recovery" to something like 53.6V like this since my system is well sized panels/batteries/load my batteries will reach almost 99% and float for about 30-60 min before reaching the "overvoltage protection" voltage, thus resetting to 100% and stopping the charge current.
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
Yes, I replied to you comments already. I will do some more Seplos testing soon. That is a great suggestion and 'trick'. Thank you for sharing this. The missing floating option is not great but also not a big problem. Usually people turn on loads when the battery is full anyway, so it won't stay there for too long. Using the recovery voltage... so when the battery is full, you just use the solar power for your loads and the battery voltage will slowly go down due to the fact that the charge MOSFETs are turned off. Ist that how you use it?

Fantastic video Andy! Thank you. You are doing a great service to the community of people that need help with learning everything solar! This BMS seems very impressive for sure! One thing that I worry about with BMS' is ONE setting... Delta cell voltage shutdown should be implemented. If you have a runaway cell it can take down the whole pack before shutdown happens at a certain pack voltage. I think I have said that I use a "naked" BMS monitoring system. Instead using Home assistant, I can set a shutdown if there is a DCV of a certain voltage. Pretty cool eh? Anyway, this is just the way I do it. Thanks again for your content. Together as a community we learn! 🐸🐸🐸

@OffGridGarageAustralia Год назад
Thanks, Dan. Using HA for that is pretty cool. Do you still have any hardware protection as well measuring the cell voltages and turn off MOSFETs in case of a runner? Only using HA might be a bit risky? I have seen DVC settings in other BMS but is this not a double up because if one cells runs away, the BMS will catch it anyway?

Hi Andy, you say the Gobel Bms is the best, because of the software, because the SOC reset can be determined. On the other hand, you mention but, the Gobel BMS switches off the MPPT and then uses only the battery, unlike Seplos, for example. For me, however, remains in total the Seplos the better BMS, because not only more user-friendly through Bluetooth, but what is much more important, the Battery is full in the summer at noon and it follows another 8 hours SUN, which I can immediately consume or feed and sell, the Gobel BMS can not, the whole afternoon is then lived on the battery, although the sun is shining and I could use the extra yield. For me, the Seplos remains the price performance winner. Thanks for your work and thumbs up from the crazy Germany to Australia

@Off-Grid Garage - thats true the Gobal BMS is one off the Best BMS on the Market right now when you what to parallel more Battery Packs. On an 3 Phase Victron System the Solar Input to Grid is possible over the Solar Charge Controller when the Battery is 100% full - so the BMS is not blocking the Feed in to Grid. The 100% Reset and turn OFF MOS is not the best solution because on an 3Phase Victron System with a Fronius MICO GRID Inverter when the Gird is Cut off and you have full Solar Power the Victron 1:0 Rule makes for a few miliseconds a higher Voltage on the DC side until the Inverter are throttled town by the rising Hz from the Multiplus. When the MOS are closed the can not drop the incoming Power to the Batteries. Also the 100% Turn OFF MOS is the natural way of Float Voltage - when the MOS Stays ON we need a extra Permameter for the Float Voltage to set for the the VE.Bus. I'm also FAN of your theory to keep the MOS ON at 100% Maybe Gobel Power can implement a Set Float Voltage for the Victron VE Bus when Batterie is at 100% and a NO Close Function from the Charge MOS at 100% SoC!

Yeah, you can parallel them if they have a matching voltage. However you will never get the best out of your batteries, it's always a compromise. The charge and discharge curves are very different and while the LFP battery is charging to 95%, the Li-ion battery will not charge at all until the voltage rises. Then the LFP will stop and all charging power goes into the ion battery. That can lead to high amps for either battery at various states of a cycle. But interesting project, I may look into this...

I have 20kWh LFP battery and I am planing to connect to it Li-ion battery in parallel (I got it dirt cheap). When LFP battery works between 55 and 48V and it's capacity is almost fully used, the Li-ion battery will only be utilized in circa. 60%. For me it is OK because Li-ion battery is than very safe.

I love your videos, but I must correct you since i have been seeing 10 videoes where you say seplos stop charging and reset to 100% only at 3,65v. I have a seplos case and it reset to 100% at 3,50v, because i have set the total battery voltage to 56v. When it hits that it resets to 100%, also when I have set the cell ov protection to 3,6v. The seplos reset to 100 percent when it hit an overvoldtage protection for the cells or total voltage you have set yourself. I use it with the 10A limiter but my deye 12kv 3 phaee inveter wants to take things easy and only charge with 5A until the battery does not absorb anymore. After that, the battery goes down to around 3,4v. Best inverter ever, 17A on each phase if all phases is loaded 100% or 27A on one phase if the total load is under 12000w forever. And it can do 200% for a small amount of time on both the 17A and 27A. And it can do all sorts of smart things, like use the generator input as smart load that turns on when the battery reaches a preset % and off again at a preset %, I use for charging a tesla. It works with alot of batteries like seplos. It have the shunt build in so it can run with no connection to the bms in % mode. It can take 18kw solarcells and run another inverter like micro inverters on the generator input, even in off grid mode I run the seplos with the neey 4.0. I got some very good eve280 cells there dont drift much. I could run it without the neey and I did for one month because I turned it off by mistake, and the call was only 25mv from each other when the battery was charged to 100%. The settings in the seplos bms its set to that the balancing starts at 30mv and stop again at 20mv, so that is exactly what it was set to do. I have the neey set to 8mv because I like the the quick balancing the neey offer, then the seplus work as a backup balancing if the neey stop working or more then one cell runs off. I have not updated the bms or anything, and it does just work. The system runs as an off grid system now, until the permit to export to the grid comes.

Yah, I agree it definitely should not turn off charging based on any internal SOC tracking. I can guess where it came from though... these BMS firmwares are typically not written from scratch by a battery expert, it was probably copied or stolen from somewhere and then modified, or they commissioned it from a boilerplate. So the likely reason is that the design is left-over from a drop-in-replacement function for lead-acid. And in that situation the charging source might never disconnect so the BMS has a disconnect at 100% SOC. You've really never liked the low balancing current BMS's have, but I think it might be a bit of over-optimization. If normal charging specifications are followed, meaning we charge to 3.55V and hold there for an hour or two each cycle, and assuming the BMS is sane and starts balancing above 3.50V without any silly restrictions like only doing it while charging current is present, then the whole system works perfectly well and no active balancer is needed.
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
But you would need to keep the battery at 3.55V without anything connected but a power supply to keep it stable on 3.55V per cell. As soon as it is still charging or discharging a tiny bit, the balancer will not work. These undersized balancers come from Li-ion where you can start balancing at any voltage. We will see the first of these kind of BMS with an active balancer soon...
@junkerzn7312
@junkerzn7312 Год назад
@@OffGridGarageAustralia Right, but generally speaking if the charge gets to that point, holding it there for a while isn't really a problem. Once the charge current tails off (30 minutes or less), then holding at 3.55V doesn't take any more energy than holding it at 3.375V would. So its just a matter of at what point in the day the solar gets it there in terms of holding for 2 hours to give the BMS's balancers sufficient time. And if there is extra time after that the charger simply drops to the float voltage of 3.375V or 3.4V and continues holding there. You have the same load-support capability either way.

I'm confused I guess also needing advise. I have (us model in usa)growatt 5000es with 6 signature solar lifepower 4 batteries. Batteries are all comm linked thru the rs485 port (one designated master)hooked to the 5000es rs485 comm port. Works flawlessly so far. My question is with the communication does the master battery talk with the other batteries(bms to bms I'm assuming)and decide which battery is to charge and which is not in order to keep them balanced as a bank and the bms within each battery to keep its 16 cells in balance?I cannot set any charge parameters or cut offs this way it is all set thru the inverter. Secondly if I wanted to build my own 16s 280ah battery using catl cells. Which bms would you use and would any you know of communicate with the growatt 5000es.I do not want to parallel the inverters. Just use as separate stand alone systems but each having communication with their battery packs.I plan on running all my 240 loads on one setup while using the other for my 120v loads. I don't like(trust)having all the inverters paralleled together and risk having total failure. I have 3)5000es and plan on getting a spare.Use 2 for 240v and a single for 120v then have the spare. Any thoughts. Sorry so long winded. Howdy from Texas!
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
Thanks for your question, Chris. The communication does not go that far. It is more to pass error or alarm states on to the inverter, show an overall capacity and also the overall deviation across all cells combined. The master BMS will not regulate the charging of single batteries though or controls the balancers. That is still part of each individual BMS in your batteries. Any BMS supporting the Growatt protocol via CAN or RS485 will work. For example the Gobelpower BMS as well as the Seplos BMS.

​@@chrislewis9345 In the battery, you select the brand of the inverter, or the battery protocol used by the inverter.

It's a protocol not a programming language or API. It how the settings are conveyed from the battery and understood by the charger or inverter.

A protocol defines the exchange process as far as the order that each device will communicate (request -> answer, field order [ie status might state the voltage followed by current draw etc in one BMS while another may send current draw followed by voltage etc]), the format used to express that exchange (is a number an integer, a floating point number, a string of characters, how many digits of a number represent the data before and after a decimal point etc) and other metadata like delay time required between each conversation, delay time expected between request and answer and so on.

The only gotcha with the 4S JKBMS is it seems to have a significant current draw. Did a test of 100AHr 12V 4S LiFePO4 with full charge and left it for 3 months and it lost 40% of capacity - fortunately there is an on/off switch that you use to easily switch on/off BMS. I have a suspicion that the current draw is due to the inefficient DC DC converter that produces >21V as this was the voltage required to drive the BMS in 16S versions.

JBD bms tells you it's 100% according to what you program into it. Maybe you need to revisit it Andy? The last one you looked at was really small and soo old. My batteries reset at 3.6 volts, where I need to program them because of the Canadian climate, instead of the 3.45 you use. We get much colder here then Australia and 3.45 is too low to charge completely at anything below 8 degrees C. Program the new JBD bms, at 2.8 to 3.45 (as an example). Test capacity by going from full (3.45 ) to empty (2.8). The JBD will now read and communicate the AH stored within those parameters as 0 to 100% . There is no need for the BMS to tell the Victron what to do if the Victron system is programed correctly. The inverter should always turn off before the battery, this is easily achieved with voltage parameters because of the LiFePO4 discharge curve. The inverter throttles down any loads at shut down, preventing spikes to the battery. Charging MOSFETS turning off is essential. Relying on an outside device to stop charging is added complication that invites disaster if something goes wrong with the communication.
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
I'm in contact with JBD and see what we can organise... That is the whole purpose of a smart BMS to tell your inverter what to do without having to program your inverter (or Victron) in this regards. I don't think it is essential to turn off MOSFETs at all. If the charger follows the BMS request it will just stop charging at the set numbers. If not, the BMS is there to catch the battery and disconnect. It's a 2-step system.
@boatelectricaldiy
@boatelectricaldiy Год назад
@@OffGridGarageAustralia I see how in your situation this will work fine, and might be the goal. In other situations, say for instance if life safety equipment is involved (like we have on ships), this setup could cause major problems. Lets say your battery shelf with 3 batteries is your main system in this example, and your backup system is the Frankenstein battery. Your main system has 3 BMS's that communicate to turn off the inverter. One of your three batteries, has a failure and turns off the inverter. You switch to the backup Frankenstein battery, because someone's life depends on having the inverter running for their medical equipment. The inverter doesn't turn on. You quickly isolate the defective battery with it's circuit breaker and switch back from your back up Frankenstein battery to your main battery. Your inverter still doesn't work, it's being told not to by the BMS of the problem battery still. Somebody dies before you can reprogram things. The same problem happens if you run the main battery bank to empty then try to switch to a backup battery. The empty batteries will tell the inverter to stay off even though a backup power source is available. By using the voltage profiles of the LiFePO4 as the triggers for the inverter, you ensure that a backup system will turn the inverter back on in an emergency. JBD makes a BMS capable of 750 amps peak, so you're not going to blow any MOSFETs like you have with other BMSs. If we are talking about massive storage installations, Victron isn't involved and neither are any of the BMS's you and I are using. A much more complicated computer control system is used for these.
@OffGridGarageAustralia
@OffGridGarageAustralia Год назад
@@boatelectricaldiy Thanks for your comment. OK, so one single BMS will not turn off the inverter, it will turn off the faulty battery bank and the inverter keeps running on the remaining batteries (we have tested this with the Seplos batteries). Also turning off the breaker or battery switch for one battery banks should also isolate the BMS. If not the order they are wired is wrong (or bad design). Switching from the main battery to a backup battery should always start the inverter, otherwise it is useless as a backup as you explained. Life saved, maybe?!

The best BMS now for your 12V LiFePO4 battery system" So I'll order a B2A8S20P unit, with your link.

These sort of BMS are all 16S for 48V battery system and communication between them and an inverter. Yeah, for a 12V or 24V battery, use the JK-BMS. that is a great device and will work perfectly with its active balancer. The screens are really optional as you can always connect via the app. There is just basic information on either screen. They are great if you install your battery in an RV and also other persons can read the information of SOC. And the on/off button... it again depends how you use your battery but the BMS should be staying connected to it all the time anyway. And thanks a lot for your support and using my links

I'm quite surprised that in this day & age, BMS manufacturers are still making those "common" mistakes. And they often are all making the same mistakes, which I find very worrying. The fact that their firmware on the BMS often can not be upgraded is a very concerning one as any bugs discovered, and you have found many, can not be fixed for their existing customers. I think the best thing we all can do is cease buying such BMSses and focus as much as possible, for the Gobelpower solutions. (and JBD haha)

Like we had with the NEEEEY balancer last year, where it took them 4 (hardware) attempts to get it right. How good would a FW upgrade function bee in these devices. I don't understand either why none of these develop a 'perfect' BMS and listen to the community, be on the ball with new FW upgrades and support. They would sell like fresh baked, hot cookies.

​@@OffGridGarageAustralia I totally agree with you, a good BMS would be a true bomberfest, like the GobelPower seems to be. Thanks to you & your channel when I was about to purchase a Daly BMS, it was one of the first videos I found you discussing it in informative details. That was a very cold shower when I watched that video and opened my eyes to dig deeper & further and I got bitten by the LiFePO4 & BMS "bug" due to you dear Andy & your wonderful channel (& informative website!).

Keep your cells balanced and rely on a real battery monitor like Victron to do SoC measurements. BMS's with a bunch of cheap non-zero temp compensated paralleled chip resistors for current shunt and non-auto offset zeroing sense op amplifiers for shunt resistor voltage sensing is not a good way to make an accurate SoC indicator.

If it came in 24 volts i would buy it but it doesnt 😢

No, it's not a consumer grade BMS like DALY, JK or JBD

@@OffGridGarageAustralia consumer grade bms just do not cut the mustard. Ive got 50 kwh batteries that unfortunately are at 24 volts due to everything thats powered by them being 24 volt, replacing inverters and everything else for 48 volt would cost far to much
