SolarEdge via LAN interface

[rogerthn]

I did try SolarEdge_ModbusTCP on bookworm with no luck
I ended up using pymodbus-2.4.0, pyserial-3.4 and solaredge_modbus-0.6.5 that I did have running on buster.
On bookworm as normal user

Code: Select all

mv /home/USER/.local/lib/python3.11/site-packages/* /home/USER/SAVED_site-packages/
scp -pr pi@buster:/home/pi/.local/lib/python3.7/site-packages/pymodbus ~/.local/lib/python3.11/site-packages/
scp -pr pi@buster:/home/pi/.local/lib/python3.7/site-packages/pymodbus-2.4.0.dist-info ~/.local/lib/python3.11/site-packages/
scp -pr pi@buster:/home/pi/.local/lib/python3.7/site-packages/pyserial-3.4.dist-info ~/.local/lib/python3.11/site-packages/

scp -pr pi@buster:/home/pi/.local/lib/python3.7/site-packages/solaredge_modbus-0.6.5.dist-info ~/.local/lib/python3.11/site-packages/

Total size of site packages 3.1MB, compressed 650kB.
Please let me know if I should try to upload the tarball
Good luck

This is how I got the modbus connection working, in buster.

Code: Select all

pip3 install modbus==0.8.0
pip3 uninstall pymodbus
pip3 install pymodbus==3.6.9

The code used runs in my customstartup.sh I use in docker.

The problem for me is more computing the correct value for raw sun production, escpecially when using a battery and ev-charger. There is actually no value in the modbus registers for the raw sun production. But I am getting there and may be I will take the occasional miscalculculation for granted.

Hi Guys,

I have found this plugin which works with my Soleradge (and also of JvdZ)

https://github.com/addiejanssen/domotic ... tcp-plugin

This is how i got it to work

Code: Select all

git clone https://github.com/addiejanssen/domoticz-solaredge-modbustcp-plugin

Code: Select all

pip3 install -r requirements.txt

Code: Select all

pip3 uninstall pymodbus

Code: Select all

pip3 install -U pymodbus==2.5.3

Restart your domoticz and check your devices



Maybe somebody know how to use the latest version of pymodbus instead of downgrading ?
Using the latetst version give the following error

Code: Select all

No module named 'pymodbus.client.sync'

[jannl]

It works here with pymodbus 3.6.9 as is in my previous post.

[jvdz]

It works here with pymodbus 3.6.9 as is in my previous post.

That indeed works too! Thanks for sharing.

EDIT: When you update requirements.txt in the plugin directory to:

Code: Select all

pymodbus==3.6.9
solaredge_modbus==0.8.0

and then run : sudo pip3 install -r /home/pi/domoticz/plugins/SolarEdge/requirements.txt
It will also be fine as the newer version of pymodbus is uninstalled in favor of 3.6.9

Hi Guys,

I've a strange daily value which i don't see in the reports or logs

2025-05-25 20_00_05-Domoticz - Overige.png (13.73 KiB) Viewed 5779 times

2025-05-25 20_03_47-Domoticz - Devices_891_Log.png (7.76 KiB) Viewed 5778 times

Any idea where this is coming from or how to correct?

[waltervl]

I have seen this reported more before. Seems to be an error on the SolarEdge side suddenly reporting strange values.

[madpatrick]

Are you sure ?
My Toon is also givin a large number and this is readingout the P1

2025-05-31 08_50_43-Domoticz - Overige.png (8.73 KiB) Viewed 5623 times

And i installed the plugin on an old Version: 2023.2 (build 15462)
Which looks correct

Isn't this the total production of the PV installation? (Labeled wrong)

Did anyone get the AddieJanssen plugin working on Pi OS Bookworm? Whatever I try I keep getting the × This environment is externally managed message.

The same happens when I try the sunspec_ardexa method.

See this section in the wiki https://wiki.domoticz.com/Using_Python_ ... ules_fails
Bookworm handles Python modules differently then before.

See also the following link where one of the plugin authors explains the issue https://zigbeefordomoticz.github.io/wik ... alEnv.html

Thank you, I actually got the message after using the second tutorial you posted: "Successfully installed pymodbus-3.9.2 solaredge_modbus-0.7"!

I can find SolarEdge ModbusTCP in hardware and when adding I get a message stating the devices are added to the devices, but none show up. Any tips?

I had the same problem and solved it by @jannl 's instruction in above post from May 05.

Has anyone managed to get the Solaredge batterie via Modbus TCP? Or any other solution to get the batterie data and integrated intoto the energy dashboard?

I have it working on my pi-5 running 64 bit bookworm using the instruction above.

I extended all python instructions with --break-system-packages

This is the dirty way to ignore the 'venv' errors
