Diehl Platinum XXXXS RS485 support

[stendec]

Hi,

Are there plans to support RS485 based Platinum inverters?

Thx!

[Martin Diphoorn]

Hi,

actually we support only the applications that gives us the data.
So if you have an application under linux that can give us the data then we can support it.

However we need to receive the output off that application so we can parse it to the values we need.

Thanks for asking!

Hi,

 

Your datalogger looks great!

I'm planning on installing it but I have the same issue as Stendec with 2 x 4301s Diehl inverters.

Would it be enough to use a "rs485 to usb converter" to get it working? Do I need a converter for every inverter or can I use one converter to read out both inverters at the same time?

I have this other program ( solarcontrol ) which I can use to read out an inverter through rs232, but this is not so convenient. I would like to have things automated ;-)

 

Regards,

 

Dirk

[Marco]

is solarcontrol compatible with Linux?

If it is, than we can used it with WebSolarLog.

[Michael]

Solarcontrol is aplication java, solarcontrol.jar with win32com.dll run under windows...

[stendec]

Hi,

I've managed to reverse engineer the communication between solarcontrol and have written a small C program that connects to my Diehl Platinum 3800S inverter via a USB-to-RS232. The program is capable to read day and detail logging from the inverter similar to the Java app.

Is there a possibility you can incorporate this into the Websolarlog application?

What information do you need for this?

Regards.

 

[Martin Diphoorn]

Hi, of course that is possible.

Which data can you provide?
How more how better!

Can you provide an json message?

Does the Diehl has history data?

Maybe you can open a ticket for it?

Also we need an test setup where we can login and see what happens.

Greetings,

Martin

That sounds great!

Please take a look at the website of Curt Blank. He is the developer of the Aurora program for monitoring the PowerOne inverters.

With Aurora its possible to output a columnized string;

pi@raspberrypi ~/ $ sudo aurora -a 2 /dev/ttyUSB0 -Y5 -l3 -M3 -c -T -d0 -e

It would be great if you could make an output like above!

[André M.]

Haha I couldn't resist:

Do you want more Diehl or less?

[stendec]

Well it's still POC but here is a few sample output's of the day detail:

I have to clean up the code somewhat before I send it.

[Marco]

Output looks promising!

Would it be possible to add a totalGeneratedKWH counter? In most cases inverters are reporting this value and WSL needs it for calculations.

[stendec]

This is the output of totals for a given day, in this example yesterday.

The Energy (Sum) [Wh] here is the totalGeneratedKWH counter.

Marco,

I can send you the example C prog I wrote for my tests which contains the detail and summary requests and also the required crc16 calculation.

Would that be sufficient?

   

[Marco]

What do you want me to do with it, because i have no Diehl inverter to run the scripts with.

I you could give me a string generated by the script with all the necassary data, then i can make WSL compatible with it.

[Michael]

Why not published the code K, to see him and read it. 

Thanks for everything.

Michael.

[Michael]

sorry 

Why not published the code C, to see him and read it. Thanks for everything.

[Michael]

Dear friend,

I trust that you are in good health.

Sorry for asking you again and again, but I would really appreciate if you could share the code you have written in C for 

accessing the data for the Diehl/Platinum inverters.

Excuse my poor English communication, so this time I asked a friend to help me with the language.

I have a small installation with 3 inverters 320 kilometers far away from my house and I would like to monitor their performance remotely.

I want to develop a program for doing that, so any code idea that you could share would help me to enhance my views about doing such an 

operation.

I apologize if I have been so insistent, but I am really at a dead end and any info would help me build up my knowledge.

I thank you in advance for your understanding,

Sincerely,

Michael

Hi Michael,

Sorry for not replying any sooner but I was not able to as I'm recovering form a serious illness.

Nevertheless please find attached the code I was experimenting with.

It is a mess so you have a nice puzzle to solve. The nohup.out is the output it generated which also proves it is working.

Keep me posted of any progress?

Have fun!
