if you wish to fully automate your process take a look at this post https://diysolarforum.com/threads/automate-solis-and-octopus-integration-to-charge-batteries-at-cheapest-hours.81078/#post-1112755

Turning off the Discharge Switch disables charging - I am sure this was not how it was intended guys, if not what's the purpose? If you turn off discharge - it is supposed to stop discharging whilste still charging.....can someone else check and confirm this is not just happening to my...

When I did electronics engineering, they taught us how to calculate the resistor resistance just from the colour coding on it...but I have completely forgotten how to. Anyway, I thought I had already measured and labelled by resistor packs but turns out that set was labelled wrong...what you...

Atomic S3 Lite CAN

@Sleeper85 @virus100b One other-thing - The Inverter BMS beeps every second since i have now removed the cable, is this normal behaviour to beep constantly, will the BMS not wear out its speaker after some time like that :) the Power BMS doesn't beep like that except when it's making that...

at rest i have a delta v on each of the strings Sting 1 = 0.030 v String 2 = 0.003 v as per the below screenshot is this what we use the Voltage Offset (which I can no longer locate in the settings - or has it been renamed) ?

Genius I didn't have a 120 ohms resistor but had a few 60 ohms and put them in parallel - as soon as I bridged it and remove the ethernet to the battery it shows green. I now just wonder why I don't have the same issue on the Solis string ...its a different BMS though, those are Poser BMS...

Hey Did your Automation work? Mine did. been using it for the past few months now I had to duplicate the script and automation to get 4 and a half hours worth of charge as it only does 3 half-hour slots originally which = 1:30 hours Here is my script for those who wish to follow: When...

Just a little guidance on the calibration aspect What do I enter into the current Calibration - I mean I have current for both BMS's, do I just choose one value and make sure it's entered the same for both?

I have made sure the BMS pair has the same voltage and Current values set # Different Topic This is why it's so cool to have HA manage your setup. - Problem I had Automation to automatically charge my Solis (1st string) (as no such integration exists yet for Sofar 2nd String) - every time it...

welcome back @ChrisG :)

Let me check again...

I have never seen my system functioning like this before - its so stable the only issue which i can live with is the fact that the SoC keep leaving each other. They marry when it gets to the top-end (%100) but then divorce after (40 to 10%) halfway through. I am not too worried about it...

I did what you suggested it read 119/120Ohms was fluctuating to other values but mainly 120...

So that's all the UAT test done for : SOL-3K-RHI-48ES on x2 JK-B2A24S15P (Power BMS) Pass (Except for someone needs to Confirm if it is Normal to have to turn off Automatic Discharge to have the Inverter Discharging) Thanks to all those involved.....

Nice Nice...

Thanks...that did it....Zero Knowledge when it comes to coding :)

As for the Discharge issue - i had to turn off Automatic Discharge for my Solis inverter to be able to discharge.

Did you make any changes to the board_atom-s3-display.yaml file? I think i am missing something - what needs to be declared? Help -

Ah so its definitely me then... thanks for confirming

Error While flashing: the board_atom-s3-display.yaml Edit Clean the build and its flashing now..

This is the board i uncommented As for Lion: I just noticed and corrected it now - Hopefully, this was why it is not discharging. For My chip - this is incorrect? As for the Sofar The model is: HYD 3600-ES It uses Protocol Pylontech (Not got this to work yet - it did with the old code...

O.k Just Flashed the Solis It say CAN o.k on the inverter - But Battery name fail It is also not displaying the SOC on the inverter . it just says 0% Also the Atom S3 Lite Display does not come on (a little disappointed :) ) so i think there is a problem somewhere... # Edit Changed the...

Nope - same result Each time i remove the bridge plug failure error on the Inverter when i plug it back in Esp starts to flash i wasn't ready to flash the Solis setup...but this is now prompting me to test it on the solis i will use exactly the same code , only change the names BRB...

And yes it is Anarchy , the behaviour right now, It's stable when i turn off or disconnect the ESP CAN, i did everything correctly - not sure what is missing i am going back to set the protocols both on the inverter and the BMS to Pylontech again - will report here

O.k - i gat to figure out why the battery throws error when i remove the bridge CAN-h/l cable to the batt

@Sleeper85 Well, the only way I could get my setup to work is by bridging the link between the ESP and the inverter and then taking the CAN-H and CAN-L back into the Master Battery BMS The ESP device is blinking so I know it's using your logic and not the JKBMS CAN logic. if anyone has a...

I know - its so nice the outcome , lol i can't wait to see how it will look when i use this chip with the screen

i understand why you got confused now..... In the screenshot where I circled the Canbus , they are both pointing to the same Entity......that is becos i was using the same card and just overwriting the entities when i was updating my cards.

The monitoring is via wireless. I am off the monitoring mode now as i got it working - as per the above screenshots.

I dont have 4 x ESP - i did and yes i know the goal is to combine, so on my second string (Sofar) i have combined the ESP; i am now only using 1 The First String (solis ) is still on the old , so have not been combined yet , that is next. As for have both string on one ESP , i cannot do that...

So Basically UAT test for sofar_hyd3k-6k on JK-PB2A16S15P (Inverter BMS) is a Pass I will be testing Solis on JK-B2A24S15P (Power BMS) next....

Found My Issue: I had the CAN polarity wrong (so just switch them over) ====================================================== My Test result with Sofar Inverter (sofar_hyd3k-6k breed) on JK-PB2A16S15P x 2 First of all, Pylon Protocol will not work when selected on the JKBMS (info to help...

According to the below - the address 0 will be master (when all Dip Switches are set to off?) and the Address 1 would be the first slave (1000) ? how do you guys translate this to 0x000 format, newbie question... # Edit - off the back of this statement.....

Thanks.. I knew there were many benefits thanks for confirming. "If you want to use an Atom S3 Lite with the new JK-BMS-PB you can follow this guide (draft)." What about for BLE - does it work out of the box ?
