some options to consider 1. easiest and most hands off just works is solar assist (just need usb to rs485 hook up to rs485 pairs on the same solarks can port as batrtium) this option shows inverter things but not much battery stuff, only soc temp etc) 2. WatchMonUdpListener + grafana will give...

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...

i dont have dual solarks but im pretty sure just one cat5 to the master

Can you please check your PM and maybe respond? Or just issue a refund for lishen cells that never shipped. Thanks

@Michael B Caro i feel like i have been reasonable, i messaged you multiple times now and i didnt want to make a public post , but seems unless someone posts here you don't respond to them so here im: I received 16x 280ah catl cells that were packaged like crap thus they were scratched, dented...

ok i either got lucky or i fingered something out, i use batrium BMS with CAN comms in place with solark 12k outdoor, last time i couldn't get it to work by using pins 1+2+g or 7+8+g to get modbus to work alongside CAN (according to their manual it should work), tried rs485 usb dongle and rs485...

55.6/16= 3.475v to batt if they are balanced you can still get to pretty much full but it would lake a long time, i personally charge at 58v, my barium default recommendation i think was 58.8v, on the discharge i do not know since i use SOC values instead of voltages

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...

thats my setup if interested, ill add another 280ah 16s box soon (dont look at the solar panel input cable that's temporary permanent there...)

much better, still jumps around and deviates but settles pretty close, we will see after one night how bad the consumed AH looks like

Abb is AC and DC rated

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

batirum is pretty straight forward, look at their site for some good how to videos

yep thanks tried and tested all of these options and you are correct, even fought with parallel ports.... even busted out my smelliscope :) ordered y cable and rs232 to eth box will mess with this probably next weekend or two

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...

This is awesome, I'm considering something like this to add another 5kw to my system and will reference this is I do, thank you

yes it connects to a busbar above the ABB and its a 5kwh (105a) battery and yes it has its own bms, there is no issue charging as solark doesnt care, smaller battery charges at a different rate than big batteries because big batteries have less resistance than the smaller one and take in more...

knowing what i know now i would buy boxes without BMS (my supplier can do that but not sure if it has all the punch outs or not) i like the boxes themselves for extra safety and it doenst look like a fire hazard to regualr peope :) i can fit 4 stacks under my stairs vs 3 stacks of cells in a...

i basically made so seplos is second layer of safety if batrium goes crazy, it doesn't do balance and only kick in when cells go to min 2.45v or max 3.70v so letting batrium do all the balancing and talking to inverter (ideally seplos never disables charge/discharge) also it talks to solar...

so i fingered it out and hooked up txdata rxdata and ground from the serial cable to home assistant via usb-rs232 (got solar assistant license and installed) for the msot part both are receiving data, but i think there is some kind of handshake happening and probably only 1 device can talk back...

ok if i only hookup receive data and ground to my usb rsr232 to my linux box i get the data without impraring the pvpro, soalr assit fails on that because it wants 2 way comms

i dont care about misleading marketing 9k/12k that's in spec sheet, but the one that gets me is the "engineered in the USA" which its not, im sure they give them specs to update firmware to make sure its compatible with local grid here etc but its def not enginerded in the usa, second monitoring...

would be easier to hard wire and port mirror via switch to capture the data, probably will be encrypted unless this esp can do man in the middle, also dongle only sends data every 5 mins which is the big reason everyone is trying to use rs485 to get to 5-10sec intervals on data visibility what...

overkill has open source bms tools on github that make it easy to calibrate, thank you to them, i calibrated and will monitor this to see if the accuracy improves thanks!

@bixelps does this output from rs232 same as you get from modbus? i got your integration installed but it doesn't seem to get data, i can confirm my HA is getting data from the usb, it looks like this:

i had ups tracking number but then they came via fedex, i think that supplier ships to another entity in California that sorts it all out and ships from there

Yeah... Nope! new acc must be a sol-ark troll

Inverters are pretty dumb, unless you fry them they will pay for a long time, the thing that might die is the confuser (control/cpu board) inside, but that should be cheap to replace

read up a bit on modbus but basically its a master to slave type of comm and that prob why soalrk stick doesnt like when you first plug in solar assistant. i think the data im getting is correct but i cant really code (network dude here) so that avenue is not feasable so i had another idea...
