Reading data from Huawei inverter SUN 2000 (3KTL-10KTL) via modbus TCP and RTU

rossko57 · September 13, 2022, 8:41pm

Well, the Modbus TCP bridge usually just lies there. It doesn’t do anything by itself, it is just like a ‘pathway’ If it has status ONLINE, that just means openHAB can try to communicate with your target device, not that it actually has communicated.

That’s okay, that’s what your poller Thing is for. That should set to (try to) execute actual Modbus reads from your device. If there’s a problem with that transaction, it should be logging detail complaints in your openhab.log.

So we have a mystery - your TCP Bridge thing drops offline periodically, but we don’t see the expected poller thing error messages.

Maybe you do have a general network problem, and the KNX reports are related after all.

I started again with a fresh openhab installation. I only configured samba and installed frontail. After this I followed the instroctiones form @Rado1. Now I get massages in Log:

Modbus TCP slave inverter is “online” and has this config:

I had to install it again. I saw the Modbus TCP slave after copeing the files form @Rado1 but i can´t config it. I didn´t installed the divide1.js and co, because i´m not sure what to do. Do I have to put the content in a newe file “divide1.js” in \openHAB3-conf\transform The software version of my dongle is: V100R001C00SPC125

Thank you!

Edit: I confiugrate the modbus TCP slave again and now my log looks like this:

Good, now we can get somwhere.

If you choose to configure using xxx.things files, you cannot edit those Things/channels from the GUI. You must edit the file(s).

This is not a Modbus problem, but looks serious as it could prevent any config changes working.
You need to fix that permissions problem.

As the message goes on to say, this Modbus data Thing needs to be a child of a poller Thing, not directly of the TCP bridge Thing. You’ve messed up your edit somewhere.

The logical structure

    Modbus TCP Bridge
       I         I
  poller        poller
  I    I        I     I
data  data    data  data

The usual way to express that structure in a xxx.things file and make it clear for yourself, the curly braces do the work

TCP bridge (settings) {
    poller (settings) {
       data  (settings)
       data  (settings)
    }
    poller (settings) ( 
       data  (settings)
       data  (settings)
     }
}

Be sure to give all things a unique name

Have you allowed Modbus TCP Communication in the Dongle?

Hello! Thanks for all that information and good instructions.

Anyhow I did setup everything as described (copied things and items) but my items don´t receive any values from the Modbus binding. Every single item is in state “NULL”.

All Things are online and there´s no error in the frontail logs.
Want to achieve modbus access through TCP.

Here are my things:

Any idea what I can do next?
I was able to connect through modbus with Windows Client Modbus software.
Inverter is online and available in the fusion solar app.
IP address for the wifi dongle is fixed.
Thank you.

Best regards,
Mario

EDIT:

Okay I got my first warning here…

[WARN ] [rt.modbus.internal.ModbusManagerImpl] - Try 1 out of 3 failed when executing request (ModbusReadRequestBlueprint [slaveId=1, functionCode=READ_MULTIPLE_REGISTERS, start=32009, length=1, maxTries=3]). Will try again soon. Error was I/O error, so resetting the connection. Error details: net.wimpi.modbus.ModbusIOException I/O exception: SocketTimeoutException Read timed out [operation ID bcf30e3b-1f6c-4b2a-9829-cc6cfc78ad39]

Any ideas what I can try next? Thanks!

I updated my Wifi Dongle from SPC125 to SPC130 today.
Warning message is still here and no values received yet.

Will try to fix it somehow…
If you have any input for me please let me know! Any help is much appreciated.

Mario084 · October 14, 2022, 12:03pm

My fault - i forgot to update the channels of the items to the modbus TCP value! Now I get my first values from the inverter!

Will update this one here with my configuration - maybe it will help others to set this up.

andy_k · November 4, 2022, 1:27pm

Where do I set this??

Mario084 · November 5, 2022, 6:48pm

I think there are several ways how to do it but I connected directly to the WIFI of my Huawei inverter and found the settings there.

I used google - 1st result is this instruction here:

andy_k · November 6, 2022, 5:12pm

Any chances doing this without an Android phone?

Mario084 · November 7, 2022, 11:44am

Yes of course. You only need the Fusion Solar app for Huawei.
With Android you have to use Huawei App Galery to get the Fusion Solar App.

Please search the internet you can find these answers there aswell.

I think my technician gave me too less rights to do this. I can’t see it

chris4789 · November 11, 2022, 8:40am

If you are a brave man you could search the web for the standard installer password

Mario084 · November 11, 2022, 8:54am

It´s possible that your technician gave you a user with restricted rights for the settings.
If you don´t know the password (and if he changed the default one) you need to contact him to activate Modbus TCP.

andy_k · November 12, 2022, 8:11am

00000a also not working. Yes I am waiting for his reply. Is rs485 activated by default or do I also have to activate it?

sukhchain_singh · November 26, 2022, 6:15am

Hi,
i have got 2 huawei sun 2000 inverters, one master and one slave connected with rs458, the master plugged with the huawei dongle wla fe, THE PROBLEM IS THAT I can’t connect to the slave inverter using node red with modbus addons. can someone please help me??

andy_k · December 23, 2022, 2:59pm

I‘ve done that but I still get the number shown

Mario084 · January 10, 2023, 2:44pm

Anybody managed to get the kWh data (which is also shown in fusion solar app (e.g. kWh imported from the grid, kWh imported to the grid) out of the modbus interface?

I was also reading about a fusion solar API but huawei support didn´t send me a token / user for this.

At the moment I have the power consumption only in my Huawei_Grid item which gets updated every 4 to 5 seconds. I don´t want to calculate everything manually when it´s available in a different spot.

splatch · January 11, 2023, 5:29pm

Try below:

Active power:

poller:
  maxTries: 1
  cacheMillis: 50
  start: 32080
  length: 2
  refresh: 5000
  type: holding
data:
   readValueType: uint32
   readStart: 32080

Yield energy:

poller:
  maxTries: 1
  cacheMillis: 50
  start: 32106
  length: 2
  refresh: 60000
  type: holding
data:
   readValueType: uint32
   readStart: 32106

Yield might require re-scale through one of data options, profile or transformation.

Thank You so much to this community for very interesting and helpful postings!

I followed the instructions (“Rado1: Reading data from Huawei inverter SUN 2000 (3KTL-10KTL) via modbus TCP and RTU with json configuration for full GIU control”) on how to set up openHAB to communicate with Huawei SUN2000 inverters (10 KTL) using the S-Dongle and Modbus-TCP. The GUI interface fits “my level of knowledge” very well.

Reading values works great!

However - I’m lost when it’s about writing values, e.g. to register 47088 (RW, ReadWrite) for control of charging (“Grid charge cutoff SOC”) the LUNA2000 battery.

I read the value fine, but there doesn’t seem to be any writing to the SUN2000, when I change the value of the item representing the register-thing. The log is not giving messages that I can understand any relevance of, which of course may be due to my miniscule knowledge.

I don’t really know what to do, but here is the code of the register-thing:

UID: modbus:data:d3c8c19bbd:f5a3face4a
label: Batteri charge-discharge
thingTypeUID: modbus:data
configuration:
readValueType: uint16
readTransform: default
writeTransform: default
writeType: holding
readStart: “47088”
updateUnchangedValuesEveryMillis: 100000
writeValueType: int16
writeMultipleEvenWithSingleRegisterOrCoil: false
writeMaxTries: 3
writeStart: “47088”
bridgeUID: modbus:poller:slave100:107

and the poller-thing code is:

UID: modbus:poller:slave100:107
label: Regular Poll 107
thingTypeUID: modbus:poller
configuration:
start: 47088
length: 1
refresh: 130000
maxTries: 3
cacheMillis: 50
type: holding
bridgeUID: modbus:tcp:71978dd591
