SRNE ASF Support - Githubissues

Fidcom commented 1 year ago

Hi, this may be off topic, but out of all your inverter integrations, this one is the most similar for the srne inverter, and some settings works better compared to the pdf protocol doc. I was able to get all necessary entities to work, but the ones related to DC voltage such as the float, bulk settings, etc., I can only read them, but not write.

number:
  - platform: modbus_controller
    modbus_controller_id: snre
    name: Bulk Charge Voltage
    id: bulk_voltage
    address: 0xE008
    value_type: U_WORD
    register_type: holding
    unit_of_measurement: "V"
    min_value: 48
    max_value: 58.4
    step: 0.4
    lambda: "return  x * 0.4; "      
    write_lambda: "return  x * 2.5; "   
    use_write_multiple: true

  - platform: modbus_controller
    modbus_controller_id: snre
    name: Float Charge Voltage 
    id: float_voltage
    address: 0xE009
    value_type: U_WORD
    register_type: holding
    unit_of_measurement: "V"
    min_value: 48
    max_value: 58.4
    step: 0.4
    lambda: "return  x * 0.4; "      
    write_lambda: "return  x * 2.5; "

When I try to adjust the slider, the error I receive is the following, and the next one if I dont use the "use_write_multiple" function.

Modbus error function code: 0x90 exception: 11 
[21:46:53][E][modbus_controller:068]: Modbus error function code: 0x10 exception: 11 
[21:46:53][E][modbus_controller:077]: Modbus error - last command: function code=0x10 register address = 0xE008 registers count=1 payload size=2

[21:55:48][D][modbus:119]: Modbus error function code: 0x86 exception: 11
[21:55:48][E][modbus_controller:068]: Modbus error function code: 0x6 exception: 11 
[21:55:48][E][modbus_controller:077]: Modbus error - last command: function code=0x6  register address = 0xE009  registers count=1 payload size=2

I don't have this problem with other settings to adjust charge current, etc. Therefore, do you have any idea what the problem might be based on the modbus error? Thank you!

Could you explain why do you multiple the input value by 2.5f? If you try to set the bulk charge voltage to 48V the command payload will be something like: Set register 0xE008 to 120.

Do you like to contribute your full configuration? I would like to add to the project.

Fidcom commented 1 year ago

This is the reason, the values needs to be converted to 12V

I'm still testing some entities to see which ones are useful for me but this is the configuration I'm using together with the jk bms

syssi commented 1 year ago

I would like to close this issue some day. Could you provide a summary including an updated YAML? What's working and what's not working yet? Thanks in advance!

Fidcom commented 1 year ago

The yaml is the same, I cant solve the problem because i dont know how to solve the modbus errors. The errors only shows when I try to change the dc battery values like float, bulk, cutoff voltages, etc. For the other settings like ac current, charge source, etc, it works ok.

Modbus error function code: 0x90 exception: 11 
[21:46:53][E][modbus_controller:068]: Modbus error function code: 0x10 exception: 11

syssi commented 1 year ago

Do you know any other (may be official software) which is able to control these values? We could try to sniff/capture some frames to compare the payload with the ESPHome modbus implementation. Do you own a OEM WiFi dongle for example?

Fidcom commented 1 year ago

Currently I do not have the wifi module and I also installed the inverter to a friend, I can only access it remotely through home assistant. I wrote to SRNE several times but never received a response. Searching for SRNE modbus protocol documents I did not find any that were more recent but some older ones. Although the description is more for the charge controller(but the address are the same), in this document is the following:

The inverter manual shows:

I tested on User and the others lithium settings but I dont remeber if i tested with SLD settings. I will try later with other battery types settings to know if that solve the modbus error, but I need to be there in case of battery settings change that i cant revert remotely.
