Integration Solar inverter huawei 2000L

[photocreative]

Joaquín I’m interested in knowing how you configured so many sensors.
I have an integrated 5kw inverter, but I don’t know the name of the sensors to later create those cards.
Could you tell me the name or the code snippet to read those attributes?

Joaquín me interesa saber como configurastes tantos sensores.
Tengo un inversor de 5kw integrado, pero desconozco el nombre de los sensores para crear luego esas tarjetas.
Podrías indicarme el nombre o el fragmento de código para leer esos atributos?

[yousaf465]

how did you separate data for each string? and which card are these?

[SimonPth (Simon)]

Create sensors from each attribute by using templates.

Heres my code for example:

cheers mate it works great

[SimonPth (Simon)]

All good, brother, glad to help.

[chipemulator]

First of all thanks EmilV2 for great Job

I have core 2021.7.2 and i have error:

Hi,

In the last few days I have been trying to put up and running Home Assistant with integration with my Huawei SUN2000-3KTL-M0.

It took time, but today I finally was able to get the first data from the inverter .

For that I must thank Emilv2, Rafal and all others that are supporting the community,

The problem I have is that I can’t reconcile all numbers I read from the inverter through huawei_solar and those I get from Huawei fusion portal.

I am trying to get daily total numbers for production, imported electricity from grid and exported energy to grid. In the post I replying to, I am looking for daily values for #5 (is counted), #6 (grid_exported_energy) and #8 (grid_accumulated_energy).

Looking at all numbers read on the sensor, both grid_exported_energy and grid_accumulated_energy are total counters, adding up all values since the inverter was first connected (like total_yeld). For daily production there is daily_yeld…

Where to get daily totals for these two measures?

Thanks in advance…

[ligeza (Rafał)]

There is only daily_yield,
For daily, monthly, yearli sensors you can use utility_meter.

One question mate have you able to achieve that dc production and consumption be shown on the same graph? Not two separate ones ?

[SimonPth (Simon)]

You use the mini-graph-card and place 2 entities on it, like so:

      - animate: true
        entities:
          - color: '#FDCA40'
            entity: sensor.pv_string_01_power

            show_state: true
            smoothing: true
          - color: '#3772FF'
            entity: sensor.pv_string_02_power
            name: West
            show_state: true
            smoothing: true

Hi,

I have problems to connect the inverter to Homeassitant.
The inverter is LAN and Wifi connected, and Homeassistant reads data from wifi IP.

Everything works fine, until I lost the internet connection or I reboot the homeassitant.

When that occurs, I have to connect to inverter, reconect the inverter to wifi and reboot the homeassitant, and it sometimes succes…

Now is working again, but is stressful.

Is it possible connect the inverter only by ethernet cable and get data from its to Homeassitant?

[andro1 (Andrew.)]

Hello all,
Thanks everyone for the contribution and insights about this topic. I have the latest firmware on wifi my dongle and I have an 8KTL - M1 3 phase. 502 port is open and via manual modubus connection I get a True response and the library is installed via pip3 and also via hacs.
My question is if somebody encountered the error of always saying that there is “another client connected.” - from hass and terminal as well. (I closed the fusionsolar mobile app and website and waited for some time).
Thanks!

[seanmccabe (Seán McCabe)]

Hi all,
Just got one of these invertors now trying to use this integration, but it just won’t work, whenever I add it and try and restart HA it just kills it. Removing the folder from Custom Integrations resolves it.
Since HA refuses to restart there is nothing in the logs.

I’ve seen some posts on updating the manifest file, but this hasn’t done anything, this is my manifest file for the component:

{
  "domain": "huawei_solar",
  "name": "huawei_solar",
  "documentation": "https://github.com/Emilv2/huawei_solar",
  "dependencies": [],
  "codeowners": ["Emilv2"],
  "requirements": ["huawei-solar>=0.1.0,<1.0.0"],
  "version": "0.2.0"
}

Perhpas I’m missing something, or there is another dependency that this needs?

Running core-2021.7.2 in Docker if the version is perhaps an issue?

Any help wouldbe appreciated.

[andro1 (Andrew.)]

try in the terminal on your pc to use the python package and see if that works before using it on HA, maybe you have the same problem as me, see above.

[seanmccabe (Seán McCabe)]

No idea how to do that, I don’t use python so not terribly familiar with it.

[andro1 (Andrew.)]

see if you receive anything after running python3 and these commands from a previous answer:

[andro1 (Andrew.)]

Hooray, Just found the answer, thanks to somebody from the Huawei forums
https://forum.huawei.com/enterprise/en/sun2000-smart-dongle-modbus-tcp-issues/thread/675885-100027?page=3

from pymodbus.client.sync import ModbusTcpClient as ModbusClient

import time


client = ModbusClient("192.168.1.14", port=502)

client.connect()


if client.connect():


    time.sleep(1)

    

    rr = client.read_holding_registers(0x7D50, 0x02, unit=1) #32080 => active_power

    activePowerInv=rr.registers[1]

    print(activePowerInv)

“The trick is to specify the unit id (equal to 1) on each read_holding call. The dongle doesn’t answer to any request if the unit is not specified.”

This works along the FusionSolar app/website.

@Emilv2 thanks for your HASS plugin. I think that the code above may need to be integrated in the plugin, because as it is now, it didn’t work, at least for my configuration (KTL8-M1, 3P + smart dongle at version 122)

Only since version 120, the WLAN dongle allows the communication via 502 port directly.
For those that need an update for their wlan dongle just login in the fusionsolar web app, https://eu5.fusionsolar.huawei.com/ go to Plants > Device Management > Upgrade Management > Add (top right) select dongle > target xxxSPC122 then your dongle should appear in the next input or search for it
It will take a while (20mins), then check the status of the update, mine stated initially as “Delayed”, then I restarted the inverter (it applies the update when the dongle restarts).

I don’t know how it works, but with LAN cable after changing in huawei_solar.py from: response = self.client.read_holding_registers(register, length) to response = self.client.read_holding_registers(register, length, unit=1) integration works for me.

Hopefully it can be integrated in the plugin.

Hi guys and welcome in this forum!
This thread is a valuable repository of knowledge about connecting to the SUN2000 inverter, so now I am able to monitor my SUN2000 inverter with hard.
I just want to share that If someone is struggling in configuring a router for accessing SUN2000 internal WiFi (especially using DD-WRT) I think that my blogpost can help with this:
