Daly BMS to Solis inverter. #81

DMIINC · 2024-11-10T20:52:39Z

As a title say. What can be done and what would you need?
Nice project you got going. Sorry if I did not read everything and possibly asking this question the wrong way.

Thanks,

Which communication (CAN/RS485/ModBus) does your Solis inverter support?

DMIINC · 2024-11-11T11:32:29Z

CAN/RS485
Solis S6-EH1P11.4K-H-US
I do have what appears to be communication manual
Thank you

ai-republic · 2024-11-14T06:19:14Z

@DMIINC could you please attach the communications protocol so that I can check?

Thank you

ai-republic · 2024-11-16T01:41:21Z

Hi @DMIINC,
I had a look at the communication specification but it does not specify any BMS data that is passed.
I also had a look at the inverter data sheet and the battery compatibility sheet:
Compatibility_List_Solis_S6_Hybrid_v2,4_08,23,23.pdf

This states that it supports the Pylontech. Have you tried to configure the PYLON_HV_CAN binding for your inverter? I think that should work. You might have to do a corresponding configuration in your Solis inverter.

DMIINC · 2024-11-19T15:22:33Z

Ok. Will try here in day or two. I will report my findings here. Thank you .

Or how would you setup this board. Please do tell. Thanks

ai-republic · 2024-11-23T02:27:10Z

Hi @DMIINC,
it definitely looks like your 2CH-CAN hat is not properly set up. Did you follow the instructions on the Waveshare Wiki?
You do not need to install the Python or the example/wiring PI code.
Which model exactly did you get? The 2-CH-CAN-FD-HAT or the 2-CH-CAN-HAT?

DMIINC · 2024-11-23T11:14:34Z

I think I solved that issue. I have another one. What do you think? I got this one https://www.waveshare.com/wiki/2-CH_CAN_HAT%2B

Hi @DMIINC,
it looks better now. It has initialized the CAN interface now. This is the start script that I use to start/configure my 2-CH-CAN-FD hat:

#!/usr/bin/env bash
sudo ip link set down can0
sudo ip link set down can1
sudo ip link set can0 type can bitrate 500000 restart-ms 100 fd off
sudo ip link set can1 type can bitrate 500000 restart-ms 100 fd off
sudo ifconfig can0 txqueuelen 65536
sudo ifconfig can1 txqueuelen 65536
sudo ip link set up can0
sudo ip link set up can1

But sometimes I get the same error that

tel.schich.javacan.platform.linux.LinuxNativeOperationException: Unable to read from the socket - errorNumber=11, errorMessage='Resource temporarily unavailable'

if the device is not connected properly.

For now - to test the BMS - I would recommend to set the inverter to the NONE binding.
My guess is that your BMS Id is not configured correctly. The Daly BMS usually starts with ID 1. You'll need to set that in the configuration. Do you just have one Daly BMS? Do you use the interface board or are you connected straight to the Daly CAN port? And does your Daly really support CAN (you often need to contact a Daly salesperson to get a CAN activated BMS)?

DMIINC · 2024-11-24T11:25:17Z

Thanks for the reply. I can use either interface board or can lines from BMS itself. I know I get canbus data out from BMS since in some combinations on inverter and BMS i will get at least correct SOC. I will try above script and see if it helps. Thank you.

ai-republic · 2024-11-24T12:55:59Z

ok, great. Yes, then I think its either the BMS id or a wrong CAN configuration (e.g. baudrate). You can set the BMS id via the DIP switches on the interface board.

DMIINC · 2024-11-24T12:58:04Z

Dip switches on interface board are all in off position. Do you suggest something different. What baud rate would you try?

but I think inverter is listening

DMIINC · 2024-11-24T13:14:52Z

ai-republic · 2024-11-25T08:19:18Z

I think you need to set your DIP with the no. 1 switch to ON. Then you should received data from your BMS. Also select the BMS binding DALY_CAN and the ID 1 and baudrate 500000.

Tried that and it does not work. Same outcome as before.

DMIINC · 2024-11-25T12:36:54Z

However what is read by your software and what inverter is seeing different. Do you suggest different settings. Amps are high and it throws errors

ai-republic · 2024-11-26T09:20:30Z

Great! You're getting data. That's a start 😄
The current looks like its x10. Is that on the latest version? Can you confirm this? Then I could have a look at it and fix it.

Attached logs includes me running my power wall today. Charging and discharging. Just FYI.

ai-republic · 2024-12-27T03:45:27Z

So here are my findings:
Daly reads dis-/charge current limits (seemingly correct)

but were actually mixed up so max discharge current held the value of max charge current and vice versa
and are sent to the inverter:

as per spec the dis-/charge current limits are offset by 3000A (with unit 0.1A = 30000).
So charge current limit of 100.0A = 1000 + 30000 = 31000
and discharge current limit of -100.0A = -1000 + 30000 = 29000
So the values transmitted are actually correct according to the spec.

The inverter then does this for:
Charge current limit:
29000 - 30000 = -1000 (which should be 1000)
wrong value: -1000 as unsigned int_16 = 64536 -> 6453.6A
correct value: 1000 as unsigned int_16 = 1000 -> 100.0A

Disharge current limit:
31000 - 30000 = 1000 (which should be -1000)
1000 * -1 = -1000 (converts the negative value to be displayed as positive and should really be -1000 * -1 = 1000)

wrong value: -1000 as unsigned int_16 = 64536 -> 6453.6A
correct value: 1000 as unsigned int_16 = 1000 -> 100.0A

So long story short, I fixed the Daly dis-/charge current limits. Now you should get the correct values if my assumptions are correct 😄

DMIINC · 2024-12-27T03:50:20Z

lol. I will test in a moment and let you know.

DMIINC · 2024-12-27T04:11:31Z

Charge and discharge current is correct. Amps and temps are wrong.

DMIINC · 2024-12-27T04:19:35Z

In ./configurator.sh I switched from Solis_hv to Pylon_hv and it is ok except Amps.

Hi @DMIINC,
please update try the Solis binding again. I think I found the bug. Now for the amps I'm still not sure. It doesn't seem to read the value from CAN id 0x4210 bytes 3 and 4 as described in the spec.

DMIINC · 2024-12-27T17:05:58Z

I do not know what you did but we have amps correct. Double checked it with amp probe too. Inverter is behaving much better. See images.
Thank you so much. Beer will be on me.
Few remaining things. Errors reported to Inverter (important), Amp hour capacity and Discharge current.

ai-republic · 2024-12-28T03:24:52Z

Hi @DMIINC,
thanks for the beer 😆 🥂
I fixed the error messages and the hopefully the rated capacity. I think it takes it from the module capacity value which the Daly does not provide so I summed up the battery rated capacity of all packs. Wasn't the max discharge current working? Otherwise I think I need to pass it as a posivite value, e.g. 100A instead of -100A. Please update and retest. If the max discharge current is still wrong I can fix that easily.

DMIINC · 2024-12-28T04:55:46Z

You are welcome on the beer. Enjoy.
Error messages are gone. :) which makes inverter very happy.

I have one more request since I am not software guru like you. I am more of mechanical/electrical engineer.

On Raspberry Pi how do I get CANBUS and your software to auto start upon boot:

#!/usr/bin/env bash
sudo ip link set down can0
sudo ip link set down can1
sudo ip link set can0 type can bitrate 500000
sudo ip link set can1 type can bitrate 500000
sudo ifconfig can0 txqueuelen 65536
sudo ifconfig can1 txqueuelen 65536
sudo ip link set up can0
sudo ip link set up can1

and

./start.sh

ai-republic · 2024-12-29T03:16:22Z

@DMIINC I've updated the Wiki How-to-use with another chapter on how to configure it for automatic start
see here

Let me know how it goes 😄

DMIINC · 2024-12-30T03:10:24Z

I can not get CANBUS command to execute at all. I have been fighting this for couple of weeks now. Actually since we started this. I am not software guru like you but I know know enough to get PI going. LOL. I am doing something wrong but do not know what.

DMIINC · 2024-12-30T03:27:14Z

Unless I manually execute

sudo ip link set down can0
sudo ip link set down can1
sudo ip link set can0 type can bitrate 500000
sudo ip link set can1 type can bitrate 500000
sudo ifconfig can0 txqueuelen 65536
sudo ifconfig can1 txqueuelen 65536
sudo ip link set up can0
sudo ip link set up can1

./start.sh will have errors.

ai-republic · 2024-12-30T05:35:17Z

Copy this to a file called startcan.sh to your home folder:

#!/usr/bin/env bash
sudo ip link set down can0
sudo ip link set down can1
sudo ip link set can0 type can bitrate 500000
sudo ip link set can1 type can bitrate 500000
sudo ifconfig can0 txqueuelen 65536
sudo ifconfig can1 txqueuelen 65536
sudo ip link set up can0
sudo ip link set up can1

Give the read and execute permissions to the file:

sudo chmod 755 /home/pi/startcan.sh

Open the rc.local file to add the calls to start the CAN interfaces and the application

sudo nano /etc/rc.local

Add the following two calls at the end of the rc.local file but before the exit 0:

cd /home/pi/bms-to-inverter
/home/pi/startcan.sh
/home/pi/bms-to-inverter/start.sh &

exit 0

Save and exit the nano editor with Ctrl+X and confirm saving with Y and reboot. That should do it really.

ai-republic · 2025-01-05T03:44:41Z

Did you get it to start at boot time now?

DMIINC · 2025-01-05T10:01:14Z

Unfortunately no. I have done exactly as you said but it does not start.

ai-republic · 2025-01-08T08:29:28Z

Hmm, that is strange. Which PI version and OS do you have?

Hello. Upon further testing I have found that Multi BMS per inverter causes invalid information to be seen by inverter. See attache d pic and log file..No matter what setting I use in regards to communication the outcome is the same. I am using interface/parallel boards.

I will check that. Maybe something is wrong during aggregation or the BMSes. But the total current and minimum cell voltage should really be working. I have also 8 Daly's in my setup.
