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...

figured out that all these lienes are modbus rtu over rs232, if i figure out how to convert that in the linux it would be easiest and probably can build that in to the homeassitnat soalrk integration project by @bixelps other option is somekind of physical rs232 to ethernet device that has...

yes, at least solark says that killing battery juice in powered on state can damage the inverter

Well if you are off grid just use this https://www.amazon.com/dp/B07FM5WQKD/ref=cm_sw_r_apan_glt_i_PWAZJ7VFKN8PE8S0K1Q3 instead of wifi dongle (rs232 port) and tcp steam to it from Home assistant

what is the baud rate etc for rs232? or are you plugging in to the wifi dongle port but it still uses rs485?

i added a separate 5kw battery before shut trip with its own fet based bms, so if the shunt trips it doesnt "damage" sol-ark since the 5kw battery will still give it juice to continue

Clamp is almost identical to victron shunt

look what i found in their doc: load of sh1t

sound like it needs to be actually checkeD?

i think when i was paying with the rs485 the only way i got rs485 from the CAN port was actually lithium mode 03 and checked, try that maybe

i looked at this solar-assistant and it seems its everything i want for the most part except it runs on PI only, HA integration, you can even change system work mode, good grafana charts... how do you like it ? seems cheap enough that i might try anyway

well this sucks, i have 12k outdoor with a single can/rs port and i have batrium bms with lithium mode 00 so solark doesn't send any data if its not in batt mode 01... first i will try to figure out pinouts if any of them are live on that "future modbus" port, if that doesnt work (i think it...

i spliced up some serial cables i had and tapped tx, rx, g and getting all this stuff, not sure if its the same data as via rs 485

i use CAN comms for battery, but when its plugged in i don't get rs485 out of it together with CAN, according to this i should be able to... hmmm ill try to mess with it again

i ordered seplos kits for all my banks as well after getting one to test

You know if it works (I think it will since rs323 is just analog interface) we can totally capture commands from pvpro and rewrite whole parameter set interface and not be beholden to Chinese soft provider

don't see any calibration option in the app, does PC app have the ability to calibrate? model in question is : JBD BMS Smart BMS- AP21S001 in 100a flavor

well thats exactly why, use their dongle to copy commands it sends to change values in the inverter, write your won front end and you can disco their dongle and still have ability to change parameters like work mode/ time remotely (i need remote since solark is at my cabin not the house and i...

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 :)

Why does your shunt trip? Mine never does
