In search for the best BMS... My Gobelpower BMS Verdict!

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.

Let’s hope all these bms manufacturers take note, it’s in their best interest, thanks for all your testing Andy🇦🇺

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! 🐸🐸🐸

Thanks for all the testing and reporting back your opinion, very helpful!

I'm looking for a BMS for two banks of 16p 280 AH cells and I came across this channel. Fantastic information, great reviews, great channel.

Thanks Andy- a really great explanation ❤️ as usual. BIG 👍👍👍

@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!

You get what you pay for as the saying goes. Been enjoying all the BMS testing.

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.

That mystery BMS is driving me crazy :-) Can't wait to see whats in the box.

[loucinci]

Well done. Great summary. Thanks for sharing

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

"this totally sucks! DONKEY BALLS!!!! CLASSIC 🤣🤣🤣🤣🤣

[Dutch_off_grid_homesteading]

Heya, it looks like for parralleling batteries you found the only bms that does olmost everything we need for or systems thanks for testing for us all

[dmytrodance]

Hey Andy, what about BMSs on Deye and Pytes batteries?

[salmankhan-ygqj]

Hey andy can i use this bms for my Voltronic inverter? As i have JK inverter bms and it is not working with Voltronic inverter i have tried multiple protocols but not working 😢😢

[StuartPittaway]

Andy, give me a shout to discuss DIYBMS!

[michaelcoghlan]

Thank you for this update an information very interesting. Have a great week, M

[Juergen_Miessmer]

Hallo Andy,
I dont know how it works, but my JKBMS always reach 100% SoC when the charge controller of the Deye is in the absorbtion phase. The Values for BMS and charge controller are set like you show on 5:52
