Nice. Can’t wait to see this in full action.
Exciting developments.
Stuart, I gave up trying to get the Trina 3kW AC coupled inverter/charger working with DIYBMS. I have ordered a Victron 5kW Multi II GX and a Cerbo GX so hopefully I will be able to get my 48V 7 Leaf module boards working. I will take a video of the working system once I have it completed. I have received the first batch of 20 boards and now fitting the CPUs and testing. So far everything is going smooth. Bolts all line up etc.
Thanks Stuart
Nice stuff mate ;) 👍
Awesome, I'm no victron guy, or even victrola, but I do dig the BMS, but this is a leap, not quite to the moon, but you almost got your rocket built!!
Thanks!
Victron is friendly to hobbyists. They provide a build of VenusGX that runs well on a Raspberry Pi 3B+ and newer. I have been using the Pi for years to manage a system with 3 BattleBorn 100ah batteries with solar in my van.
I think a few people are going to try our the pi and a can shield to see if it works
I just ordered some victron stuff...
The physical connection looks pretty easy, the software needs probably a bit more work.
Nice progression :-)
I've got most of the software interface already working, look out for the next video
For sure ;-)
Morning from Australia. Looks good. Could you point me to the circuit for the control board with display please, as I think a couple of part where missed by JLBPCB. I did try to post on the openenergymonitor group, but couldn't work out, which thread to put it in too.
github.com/stuartpittaway/diyBMSv4/tree/master/ControllerCircuit
That is the link to the controller PCB and circuit
@@StuartPittaway Thanks Stuart, hope you are well. To your whole family, stay safe, all the best from Australia.
Great share, specially the opening of the Cerbo: Now I don't have to open mine that just came in 😃.
Can you tell me:
a) the BMS type and brand? (I use Batrium which is very neat and very configurable)
b) cool stripping tool!, what brand and type?
Keep up the good works!
Hello, the BMS is my own design - diybms, plenty more videos about this on this channel.
The cable stripper is "C.K Automatic Wire Stripper"
what is the JP5 for, does Victron equipment work with 3,3 or with 5V?
It allows you to pick the voltage of the connection. The default works fine for victron
Cool video, can you explain why it was necessary to solder a resistor to the circuit board...does it not come complete from the factory.
Resistor or the jumper? I think I soldered a jumper pad closed
Forgive my lack of technical jargon. I ment the solder joint /bridge on the board. Why is that necessary. I'm new to electricity etc
@@Xxxcappie23 ok, it's just like a switch, you solder a blob on the connections to join and enable an optional feature on the board
Interesting development Stuart, cavorting with the non open source enemy or sensible collaboration? I guess time will tell. (PS, I have no problem with what Victron produce)
They do make very good kit and a lot of hobby setups include the victron inverters or chargers.
@@StuartPittaway Great answer, in reality there is room for all tech regardless.
I’ve got batteries with a PACE BMS! I am trying everything to get communication between the Cerbo and the Batteries. This has got to be the most frustrating problem :-( if anyone has managed it; please do let me know!!
does it work for SMA too?
Unfortunately not, completely different protocol for sma
@@StuartPittaway does it mean the board can communicate over CAN bus with Victron inverters only?
But what does the Victron enable that the DIY BMS doesn’t…confused by video really.
You'll see in the next video. It allows the BMS to tell the charger or the inverter what to do, this isn't possible with the native diyBMS. So for instance when to start or stop charging, what current to use etc.
Proprietary interfaces...
On the victron kit? Ve.direct.
@@StuartPittaway Proprietary interface on system (solar for e.g.) build of multiple different vendor components always smell fishy to me and certainly (these systems) will outlast companies introducing proprietary stuff. Legacy proprietary formats (digital and physical) already pain in the ass for decades. No need for more.
Bit longer comment. I should added 'sigh' on previous one.
@@mindaugasstankus5943 agree. These interfaces are on the victron stuff not mine by the way!!
This is wrong, victron is a very expensive not diy spirit. Is a diybms like batrihum
So don't buy it? This is not necessary for the function of diyBMS, it's purely a supplement of additional capabilities shown by using standard protocols.
@@teejmiller if you say
Correct, this is optional and many users have asked for it!
Victron is expensive - but no more then other quality inverters. I have had a Victron Quattro running since 2009 - without a single hiccup and its nearing the end of 2021 as I write this....not too shabby eh ? I'll take 12 years without a single issue thanks. Yes it cost upfront but 12 years down the track its running perfect. How many Chinese inverters would I have gone through in those 12 years? The DIYBMS hook up with Victron is a very good thing.
I don't use DIYBMS because it's cheap, I use it because it's the best BMS that I have found, with the most features and flexibility. Same reason I use Victron for my inverter. Yes, Victron isn't cheap, but they do support the DIY spirit by giving their software out freely to be used on Raspberry Pi, and allowing all sorts of projects (open source and otherwise) that use or interface with their hardware.
