Just curious if you’re still using the Batrium and Sol-Ark in communication as described in this thread? Sol-Ark 12K? Indoor or outdoor model?
If so, which firmware version are you running?
Sol-ark + batrium canbus integration workaround until its supported
- Thread starter audreez
- Start date
If so, which firmware version are you running?
Yes but I have some pending changes, I will be moving my bank into the Seplos Mason kits & use the Seplos BMS. Main reason is space limitations in expanding my storage, Mason kit format will work better in my situation. My model is an indoor (1.1.2.2).
i ordered seplos kits for all my banks as well after getting one to test

So what are the advantages of the Sepolos versus Batrium?
Assuming you need a Sepolos for every battery pack? So 16s4p would require 4 Sepolos?
Is there any kind of closed loop communication between Sepolos and Sol-Ark?

So which Batrium do you have? Are you keeping it or going to sell it?
I believe the latest version v3 has active balancer option, see Andysgarage YT channel, has a review on them. I have the version before it, passive balancer, similar to my current Batrium. In short yes but you could do just a couple, one per 16s2p. Yes, I be.I’ve out of the box it supports DEYE aka Sol-ark.
I am at least a week or so away from getting my 1st mason / BMS setup, will have a total of 5 to build.
WatchMon 4 with the M8s, most likely yes, sell it.

Thanks for the info. I’ll definitely check it out.
Please post on the progress and how things go. May have to eventually update at some point myself. If this works well and communicates well with Deye/Sol-Ark, I may have try it if it’s an improvement over my current setup.
i like the mason boxes for the extra safety and smaller stackable footprint than my DIY rack with selves
seplos emulates lg resu so yes it will work with soalrk (actually lets you choose from 5-6 option in the setting for BMS comms and works with most inverters)
my plan is to use seplos and connect it to solar assistant to get battery data in there along side the solark sicne solar assist doesnt support batrium directly
im planning on keep using the batrium for closed loop and cell balancing (core with m8's) i love the flexibility of settings and added safety of shunt trip breaker that batrium controls in case one of the cells goes haywire

Seplos Bms's V2 and V1 communicate with deye/sol-ark and sunsynk like a charm too..
At this point NOT a big fan of the v3 BMS at all

Just use the sol-ark native deye protocol..
Why the LG ?
I will miss the relay option that the Batrium has since I believe Seplos does not offer that at this time.
if you plug in like pytes mason box etc thats setup for sol-ark closed loop to victron gx they all show up as lg resu battery, lg resu is based on CANBUS standard spec and is the "native" to sol-ark even if they dont know that

Erm , no..if you plug in like pytes mason box etc thats setup for sol-ark closed loop to victron gx they all show up as lg resu battery, lg resu is based on CANBUS standard spec and is the "native" to sol-ark even if they dont know that
Seplos uses their implementation of the pylontech protocol either over CANBUS or RS485.
inverter specific protocols can be chosen, but they are seplos's own implementation
here's what i see
with victron:
and with "pylontech"
maybe pylontehc is lg resu based? or they are both very similar to standard canbus implementation ?
this is pytes battery setup for sol-ark dip settings

This is a Victron thing...
Even at Andy's ( off-grid garage) the battery identified itself as seplos
Is this the v3 BMS ?
dont think its a victron thing
if i change the seplos mason box to sunny boy it shows "SHEnergy"
also i have a 5yo seplos v1 based battery pack that shows up as "pylontech" by default
pytes battery whe nset to victron dip switches shows up as "Pytes"
so name does change with diff protocol implementations
not sure who is andy but im jsut sharing what i have found experimenting, even with batrium project lychee emulates lg resu protocol and works with sol-ark, even tho when i asked them they said lg resu is not compatible wit "their" inverter
pretty sure my bms is v2

Where did you purchase the mason kits?
Sepolos directly or is they’re a US seller/dealer?
Are there any other options like this?
I’d like the boxes (Mason kits) but not all the Sepolos equipment.
From Seplos directly (via Alibaba). Unsure but it seems like this model size (280a - 304a support) is used by a number of vendors (EEL, Seplos, Apexium) A review / build of the latter was done recently by a couple folks:
Appears they all use similar BMSs but I guess you could ask them to sell you just the box with no internals...
What BMS would you use instead?

I would like to still use Batrium and just reconfigure things to fit on those boxes. At least try one box and see. Experiment.
PS: Thanks for the info and links. I’ll look into those.

you can get a box with no internals, i know a dealer that stocks apexium in USA and you can order them in whatever flavor/combo/without BMS from china (also supports heating)
i have one apecium for few months now i have been testing and i like it a lot, even the BMS
4 more boxes are coming tomorrow from china with heating, planning on running batrium and seplos together and build a bypass for spelos if something goes wrong
got my seplos boxes, boxes themselves are good and i like them a lot (got heating pads too)
seplos BMS it self is MEH at best, lots of weird caveats, i was going to try and run them alone but issues like you can pull data to solar assistant via rs485 if CAN bus is configured and other weird stuff made it not viable for me
so increased/decreased all voltages/protection on seplos by 0.05v, disabled balancing etc and added batrium back into the mix, batrium talks CAN to salark, setup rs485 paralleling on seplos and hooked it up to solar assistant and i can see all 4 packs individually and their hi/low cells etc, been running for a week or so and im happy how i works and getting data everywhere i want is fantastic
one thing left is to pull the heating pads off the seplos and control it via batirum so the shunt can calculate draw correctly when its heating the batteries

Very nice! So, as a redo, would you spend the money for the seplos boxes, or get the cheaper boxes and use the system you already had?got my seplos boxes, boxes themselves are good and i like them a lot (got heating pads too)

Just to be clear, you have basically stacked the BMS’s to use the best portions of each? Love the way it looks, so clean and not wires everywhere, like on my frankenboxes. Finally have my Batrium running nearly flawlessly and the n the cat got in my area and pulled the com wire. Took me a minute to figure out this was the issue. I only have 4 280ah batteries on k-9s on the other side of the shunt I am running 4 280ah with jbd’s. I don’t love dealing with the shunt trip popping off once in awhile and not knowing unless I go down in the crawl space where the batteries are located. I was entertaining the idea of grabbing some of the basen green boxes for $553 including shipping USA stock. I also found some no frills boxes but they need to ship from China $3000-ish for 10. Still on the fence about which way to go???got my seplos boxes, boxes themselves are good and i like them a lot (got heating pads too)
