Daly BMS to Solis inverter.

[DMIINC]

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,

[ai-republic]

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

[DMIINC]

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

[ai-republic]

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

[DMIINC]

RS485_MODBUS Solis PV Grid-Connected Inverter.pdf

Thank you

[ai-republic]

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]

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

Tried can0 also but no dice. What you think. Thanks, Using board from your recommend list Waveshare 2CH-CAN hats. Anything special for it?

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

[ai-republic]

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]

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)?

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.
