Support for Sofar HYD 10ktl-3ph Serial number : SP2ES110N6E056

[juraurban]

Hi everyone, thank you for first promising integration for my solar inverter.

I have Waveshare RS485 -> WIFI - DINRAIL modul connected to inverter. But as I have expected this integration does not support my model - would you be so kind and add the support.

Log says: "unrecognized Sofar inverter type - serial number : SP2ES110N6E056"

Thanks a lot Jiri

[wills106]

Just added the Serial for SP2 Inverters in 0.7.0b42

[juraurban]

Thanks, It getting some data but most of sensor value is unknown except for: [sensor.sofar_heatsink_temperature_1] = 38 [sensor.sofar_ambient_temperature_1] = 47 [sensor.sofar_module_temperature_1] = 39 [sensor.sofar_serial_number]= SP2ES110N6E056

[wills106]

I tried to add in some more sensors compared to a previous version, but I don't know if any one has tested it or not?

I'll delete that section out and release 0.7.0b43

[wills106]

You can try 0.7.0b43 now.

[wills106]

Do you have a Modbus power meter on your Inverter or just CT Clamps?

[juraurban]

modbus power meter

[wills106]

Do the rest of the sensors work? Or does anything after this sensor stop working?

[juraurban]

it seems that everything after stops

[wills106]

Would you be able to help trouble shoot by editing your local plugin_sofar.py file? It will save me having to release so many releases.

I can explain what to do.

[juraurban]

no problem I am available for 1 more hour to assist

[juraurban]

what should I change in the file?

[wills106]

https://github.com/wills106/homeassistant-solax-modbus/blob/3761d0a4b20bd255083f23f4bbfcec9a73dba7f3/custom_components/solax_modbus/plugin_sofar.py#L242-L252

Each sensor / entity is broken into blocks. As it's failing on 0x484 if you edit Line 251 from

https://github.com/wills106/homeassistant-solax-modbus/blob/3761d0a4b20bd255083f23f4bbfcec9a73dba7f3/custom_components/solax_modbus/plugin_sofar.py#L251 to allowedtypes = HYBRID | GEN2,

this will then stop the Integration from trying to read that register.

Would you be able to repeat that on any register where it fails with:

Sofar error reading holding registers at device 1 position 0xnnn NoneType: None

You will need to restart HA between each change.

Does that make sense?

[juraurban]

will give it a try, and let you know

[juraurban]

I have been editing that line - right now I am at - should I go on with that? - It seems none of that registers Is working: SofarModbusSensorEntityDescription( name = "Grid Frequency", key = "grid_frequency", native_unit_of_measurement = FREQUENCY_HERTZ, device_class = DEVICE_CLASS_FREQUENCY, register = 0x484, newblock = True, scale = 0.01, rounding = 2, allowedtypes = HYBRID | GEN2, ), SofarModbusSensorEntityDescription( name = "Active Power Output Total", key = "active_power_output_total", native_unit_of_measurement = ENERGY_KILO_WATT_HOUR, device_class = DEVICE_CLASS_ENERGY, register = 0x485, unit = REGISTER_S16, scale = 0.01, rounding = 2, allowedtypes = HYBRID | GEN2, ), SofarModbusSensorEntityDescription( name = "Reactive Power Output Total", key = "reactive Power_output_total", native_unit_of_measurement = ENERGY_KILO_WATT_HOUR, device_class = DEVICE_CLASS_ENERGY, register = 0x486, unit = REGISTER_S16, scale = 0.01, rounding = 2, entity_registry_enabled_default=False, allowedtypes = HYBRID | GEN2, ), SofarModbusSensorEntityDescription( name = "Apparent Power Output Total", key = "apparent_power_output_total", native_unit_of_measurement = ENERGY_KILO_WATT_HOUR, device_class = DEVICE_CLASS_ENERGY, register = 0x487, unit = REGISTER_S16, scale = 0.01, rounding = 2, allowedtypes = HYBRID | GEN2, ), SofarModbusSensorEntityDescription( name = "Active Power PCC Total", key = "active_power_pcc_total", native_unit_of_measurement = ENERGY_KILO_WATT_HOUR, device_class = DEVICE_CLASS_ENERGY, register = 0x488, unit = REGISTER_S16, scale = 0.01, rounding = 2, allowedtypes = HYBRID | GEN2, ), SofarModbusSensorEntityDescription( name = "Reactive Power PCC Total", key = "reactive Power_pcc_total", native_unit_of_measurement = ENERGY_KILO_WATT_HOUR, device_class = DEVICE_CLASS_ENERGY, register = 0x489, unit = REGISTER_S16, scale = 0.01, rounding = 2, entity_registry_enabled_default=False, allowedtypes = HYBRID | GEN2,

[juraurban]

I stopped at - added GEN2, but error appears "Sofar error reading holding registers at device 1 position 0x584 NoneType: None"

  SofarModbusSensorEntityDescription(
    name = "PV Voltage 1",
    key = "pv_oltage_1",
    native_unit_of_measurement = ELECTRIC_POTENTIAL_VOLT,
    device_class = DEVICE_CLASS_VOLTAGE,
    register = 0x584,
    newblock = True,
    scale = 0.1,
    rounding = 1,
    allowedtypes = HYBRID | PV | GEN | GEN2,

[wills106]

I think you might be having some comms error then?

What's the exact model of WiFi Waveshare?

I don't have any proper confirmations of WiFi Waveshares working. Someone was trying to use one on a SolaX X3 Mic and I was having to tell the Integration to only read 7 registers at a time. Where Modbus is meant to be able to read over 100 at a time.

Do you have access to a RS485 - USB adaptor?

[juraurban]

https://www.amazon.com/Rail-Mount-Converter-MultiTransparent-Transmission-Configuration/dp/B0B54TGG1R

[juraurban]

unfortunately dont have RS485 - USB adaptor, any advice how to test it anyway?

[juraurban]

Yes, you were right. When I leave just few sensors in the file. Then it loads. I.e. I have been able to load: PV Voltage 1

SofarModbusSensorEntityDescription( name = "PV Voltage 1", key = "pv_oltage_1", native_unit_of_measurement = ELECTRIC_POTENTIAL_VOLT, device_class = DEVICE_CLASS_VOLTAGE, register = 0x584, newblock = True, scale = 0.1, rounding = 1, allowedtypes = HYBRID | PV | GEN | GEN2,

Any Idea how to query maybe in batches?

[wills106]

I'll have to create an extra file split up.

When we were working on the first Sofar HYD20KTL the owner had to make a change to the normal Ethernet Waveshare in the Wiki

https://github.com/wills106/homeassistant-solax-modbus/wiki/Installation-Notes

SolaX in "more advanced settings", set Modbus Gateway Type to "Simple Modbus to TCP/IP mode"

on Sofar Solar Inverter's Modbus Gateway Type might need setting to "Auto query storage type"

Can you find anything like "Auto query storage type" on your WiFi one? that might sort your communications problem out.

[juraurban]

I saw that note in wiki, but I could not find any option like this. This is what I can see:

[juraurban]

[juraurban]

I will check with the manual Waveshare ... if there is any option you suggest: "Auto query storage type"

[wills106]

Looks like you have the same Waveshare as the X3 MIC that's having issues.

Is there any chance you can get Ethernet to your Inverter?

[juraurban]

Ok ... I will get ethernet one and test again

[wills106]

I don't want people to spend more money on their hobbies. But I have no way of confirming if these WiFi ones work correctly. So I don't know if we are wasting time trying to trouble shoot a problem that doesn't exist, if the WiFi ones truly aren't compatible.

[juraurban]

Did you mean the functionality which is described in ethernet only Waveshare manual in chapter 7.2? https://www.waveshare.com/w/upload/6/66/RS485-to-eth-b-user-manual-EN-v1.3.pdf

[juraurban]

that version apparently has some kind of cache which send the requests in batches if I get it right

[wills106]

I don't connect via RS485. So I don't know the differences nor have the ability to test anything sorry.

[juraurban]

ok. I will order ETH version and let you know, if it works. Thanks a lot for support

[juraurban]

ETH version at home, had to set "autostorage parameter" and up and running smoothly ;) Have used updated sofar files from [reklame33] which helped to fix some entity values.

Thanks a lot for support

[wills106]

I haven't looked into the changes yet, I have been too busy.

I am glad the Ethernet Version is working. I'll add a note to the Wiki saying the WiFi version isn't supported.

[wills106]

When you turned on "Auto query storage type" Did "Enable RS485 Multi-Host" & "Enable RS485 bus conflist detection" become enabled as well?

I am trying to work out what #204 is required to do in order to get their Sofar Inverter working with the Waveshare.

[wills106]

Are the connections on your KTL inver the same as what's on @superino1 ES Inverter?

Also did you use the default address of 1 or was your Inverter set different?

[superino1]

Where do I find that value relating to my inverter? I tried 1 and 4

[juraurban]

1) Did "Enable RS485 Multi-Host" & "Enable RS485 bus conflist detection" become enabled as well? >> yes both, without that wasn’t able to save the settings 2) address is default = 1

[juraurban]

Reading is fine, but I would also like to tell inverter to charge at specific time - when spot price is cheaper. How can I make this happen?

[superino1]

Ma non è che la mia porta sia disabilitata? La spia blu su ACT sta sempre accesa fissa.. Confermo che l'indirizzo è 1

[superino1]

I'm about to throw it all in the trash😔😔😃

[wills106]

I am going to close down as the Integration now supports 'SP2' Inverters.

Any further issues, please raise a new issue.
