Huawei SUN2000 Inverters

[sammyke007]

Hi

Last week I've had solar panels installed with a Huawei SUN2000-4.6KTL-L1 inverter.
I have a (Belgium/Fluvius) smart meter installed so I can read everything with a Youless device from the P1 port of my smart meter.
There's one value however that I would like to see extra in my Domoticz: the actual provided output power from my PV (and maybe later the Yield Today en Yield Total).

Anyone that has this running already?

Data is provided in the cloud on https://eu5.fusionsolar.huawei.com/. This can be read from an app or using a web interface. There's also an API available.

I've found this: https://github.com/wlcrs/huawei_solar/tree/develop but I have no idea how to make this work with Domoticz.

Hi Sammy,

this _can_ be done, but requires some work:

1. Try to get yourself a developers account for the data which is collecting. This request MUST be submitted by the company who installed your converter.

Send an email to "eu_inverter_support<at>huawei.com" with the following:

I hereby request an openAPI user account to access the data from my inverter through the new #FusionSolar API:
System name: XXXXXXXXXXXXXXXXXX (serial no)
Username: [email protected]
Plant Name: City and adress
SN Inverter: XXXXXXXXXXXXXXXXXXXX (serial no)

You will receive an excel form to be filled and submitted by your installer (if not from them, it will be refused)

2. When te account is created you can use a (bash) script to retreive the "real-time", hourly, daily and yearly data from their website which 1 updated every 5 minutes.

Real-time is updated every 5 minutes, so it's more "almost real time"

I collect this data every 5 minutes and write it to Domoticz (real time data) en and to influx (hour, day and year) to produce nice graphs.

My scripts need some cleanup before I can share it, it's still some work in progress.

Tnx Jeroen! I've started running HASS (Home Assistant) next to Domoticz because they have a custom integration for these inverters. It reports almost everything available. It gets its data live from the inverter itself (by connecting to the inverters AP) and it's working perfectly fine over here. I use automations in HASS to send this data over MQTT to Domoticz.

Hi Jeroen

How does home assistant connect directly to the ap off the inverters ?
And were you able to push the data from HA to Domoticz?

[MikeZ]

Hi Jeroen,

Would like to use your script
I had it all working with the API version from beginning 2021

Are you able to share some?

Sammy,

how do you call the API from the inverter? I'm very interested in that . Can you share any documentation and or links?

Thanks a lot,
Jeroen

Hi Mike,

I will try to document my script the coming days and see if I can publish it somewhere (Github or so).

It's this Home Assistant integration that I'm running:

Hi Sammy

Looks great!
Stupid question though: if HA is connected via WiFi, how do you enter the UI from HA ? Or do you use wired connection also to connect to your network and the internet?

Many thanks

[sammyke007]

My Home Assistant is connected thru LAN (ethernet) and my connection to the Huawei AP (192.168.200.1) is done via wifi. You can use a Pi or a homeserver with a wifi USB stick.

It is explained over here:

I just released my first version of the script to read the production details from the huawei website. It is required to have your inverter communication with Huawei of course

hello, i looked your code, can you explain the config file, i don't understand all params, can you comment them?

thank you

[JeroenG]

Hi,

Just uploaded a more detail readme and added some more info in the .env file.

More improvements to come

[ssk17051980]

is anyone willing to integrate a huawei 2000 inverter in domoticz?
I don't have the necessary skills. I can pay for this service

[waltervl]

Everything you need to know is here: https://github.com/GoumJer/Huawei_Sun2000

[ssk17051980]

i made the admin user.
but if i try to login whit that new user, is not working.

in that link that i receive in the mail, from the foto atached, i can't login whit the main user and pass.

[ssk17051980]

what is that " domain name of the management " ?

Hi everyone!

After a year of operation, I have finally integrated my Huawei SUN2000 inverter
I found some Domoticz Python plugins, so I decided to develop the plugin created by JWGracht (thanks) a bit further. I implemented connection error handling and a polling time that can be adjusted from the plugin parameters. I tried to collect all the parameters I thought were useful via Modbus. The updated plugin also handles voltage, current, power, energy, status, error codes, alarms, and temperature data.
Although it is not new, I thought I would share it here as well, in case it is valuable to someone.

[dankogabor]

Csuti, can u help me, what the problem with your plugin?
I installed it
pip3 install huawei-solar
cd ~/domoticz/plugins
git clone https://github.com/csutihu/Domoticz-plu ... verter.git
sudo systemctl restart domoticz

After that I create Hardware in Domoticz and in log i can see this:
