as the title says i played around with integrating sol-ark with batrium because it was raining and i'm tired of waiting for official support, i played with batrium pylontech and some other emulators but they didnt work very well or at all, eventually i set it to "project lychee" protocol that emulates LG-Chem resu protocol and sol-ark understands it all just doesn't seem send data back in a fashion that batrium understands. On sol-ark set to lithium 00, I made multiple tests by changing charging voltages/current and sol-ark obliges within seconds, soc from batrium is updated on sol-ark as well, nominal capacity doesn't seem to update after initial integration but removing the lithium integration and enabling it again updates it (or just set it in sol-ark), i have my batrium setup to long life lipo so once cells hit 3.5v soc updates to 100% and batrium sends 0 current to sol-ark, then solark redirects current back to grid within seconds (tested this few times by turning off solar letting it consume ~10 amps then turning it back on to make sure its consistent and it was)

you can use a regular cat5 network cable but only use pins 4 (solid blue - can hi),5 (blue/white can lo),6 (green ground) no resistor and wire that to watchmon (mine is wm4)

see pics and hopefully this helps someone to get by until official integrations happens (its been "in progress" for a while now)
P.S. batrium does say canbus interface is in timeout status but seems like tx/rx go up and everything works ok

still working no problems, i do have latest firmware for my sol-ark
I did receive the latest update but not sure when the “last” update was. I do not have my LiFePo4 batteries connected to sol ark yet.
The extra wires in the Cat 5 cable, did you strip the out or just cut them? Pictures?

i made my own cat5 so i just crimped 3 required wires and cut the rest off, didn't want to short them out by accident if they were live

If Sol-Ark and Batrium are now communicating via CANbus, using Project Lychee protocol, how does this affect your Batrium settings in relation to the Sol-Ark settings? Charge/Discharge etc..?

solark obeys settings sent from batrium (charge/discharge current etc), unless you have max A charge discharge specified in the sol-ark less than in the batrium then it will not override that setting (it will jsut top out at that), seems like capacity is still a manual thing but not a big deal
