New Python plugin: Domoticz SolarEdge_ModbusTCP

AddieJanssen · Wednesday 30 September 2026 17:38

4. The solaredge_modbus library has been archived and needs attention.
Currently working on replacing this library.

2. The detection of meters and batteries in the meters branch may not work for all inverters.
I introduced the scanner to figure this out. Based on the feedback so far, I have a pretty good understanding on how SolarEdge implemented the Sunspec and how batteries are handled by the different software versions of SolarEdge.

I am planning to release an update of the scanner that will be based on the replacement of the solaredge_modbus library.
Hope to get this out in the next 2 weeks.

Once that is done and we don't see issues with it, I will replace the solaredge_modbus library of the plugin.

So basically you say start testing when the new branch is out. I wonder because i have
General: SolarEdge ModbusTCP - Inverter - Storage Control Mode with
0 Disabled
10 Maximize Self Consumption
20 Time of Use
30 Backup Only
40 Remote Control

General: SolarEdge ModbusTCP - Inverter - Remote Control Mode
0 Off
10 Charge from excess PV power only
20 Charge from PV first
30 Charge from PV and AC
40 Maximize export
50 Discharge to match load
60 unused
70 Maximize self consumption

General: SolarEdge ModbusTCP - Inverter - Storage AC Charge Policy
0 Disabled
10 Always Allowed
20 Fixed Energy Limit
30 Percent of Production

Together with all the solaredge functions (Meter1 - Total Imported Energy (Active) , Meter1 - Total Exported Energy (Active), Battery1 - State of Energy, To(+) / From(-)_Battery, Solar_Total and all the others), and some of them i've had to shorten the name ... the names are used in several functions so i dont know how much work the transfer will be .....

Sorry, but I don't understand your message...

Sorry i formulated the question the way i did.

I have the inputs that i wrote and there are several outputs to the plugin, i have renamed a number of them and i reused them in a number of scripts.

I was wondering how much work it would be to transfer to your new format.

Hi all,

Although the flu has been slowing me down over the last week, I have been able to do a lot of reading up and investigating.
I think I now have (famous last words...) a pretty good method to scan for all the stuff that is attached to an inverter.

I have updated (and MOVED) the scanner which is using the new methods that need testing.

The scanner, by default, can now dump all registers it has read to the output; it does so by default, but that can be stopped on the command line.
That output enables me to simulate an inverter and test my software against it, without having access to such an inverter!
If you do not want to share that output on a public forum: please share it in a private message with me!
I really need a lot of these dumps to make sure that the software works as expected.

So, although you may have already done this before, would you be so kind to run the latest scanner and share the output with me?

You can find the scanner and instructions how to use it on GitHub: https://github.com/addiejanssen/solaredge-scanner

Thanks again!

Be assured I will let the scanner run. But most likely I don't have access to my home before Monday.

I was triggered by the respons from imautohuttraeger because he has the same inverter

I ran the old file and AI sees i ran it with the connection 168 instead of 186 ... sorry for the confusion.

Actually, that sort of things usually happen to me an not to other people.

Here is the result of scanning my SolarEdge SE3000; hopefully, it provides the desired information.

Thanks all! This is exactly why I need your help.

It's clear that reading the battery details is not working at all. I will look into that later this week.

On the positive side: I have used the information you all provided to start creating a replacement of the solaredge_modbus library.
Focus is on the values that do work, next step is to look at the stuff that isn't working (mainly optional values that SolarEdge did not implement).

Here's a glimpse (based on a scan of hjzwiers) of the things that do work:

Looking at the SunSpec info: all these "7xx" blocks are the replacement of the "1xx" and "2xx".
That's why I want to make sure that I can decode them now and not push the topic forward in time.
Impact of that is, that it will take a bit more time to come up with the next version of the plugin and adding stuff like power control.

That's it for now - back to work tomorrow. I will monitor the forum, but will for sure not have a lot of time to respond over the next few days.

I did some more probing on the battery
Scanner13 results:
SunSpec models 701–713 are present. Model 713 is readable and contains valid SoC: raw 2778 with Pct_SF −2 = 27.78%. WHRtg, WHAvail, SoH and Sta are 0xFFFF, i.e. not implemented.

Proprietary E100 battery is fully readable: 23 kWh, 5 kW charge/discharge, SOH 96%, SOE 27.78%, status 3 (discharging).

E172 current = −0.1768 A and E174 power = +144 W at 820.5 V. V×I = −145.1 W, so magnitude agrees very closely; apparent issue is sign convention, not invalid data.

E200 responds as a battery identity but has Modbus address 255, empty firmware/serial and all numerical fields not-implemented/zero, so it appears to be an unused battery slot rather than Battery 2.

E18A/E192 both return zero. Registers beyond E19A/E29A don't return normal Modbus exception frames; the inverter simply gives no response.

  0xE200: SolarEdge / Home Battery 48V - 5 modules / DID=0 / Modbus=255

Model 713 is decoded according to the published SunSpec DER Storage Capacity definition.
Battery float decoding shown as the installed plugin's little-word interpretation plus raw words.
Exception probes report actual Modbus exception codes when the inverter supplies them.

READ ONLY. No Modbus write operation exists in this program.

"""
SolarEdge Developer Diagnostic Scanner 13
READ-ONLY diagnostic scanner.

Goals:
  - Decode SunSpec model 713 using the published DER Storage Capacity model.
  - Verify the installed plugin's proprietary-battery word-order decoding.
  - Read the exact event-log registers used by the installed plugin.
  - Capture Modbus exception codes instead of reducing failures to READ ERROR.
  - Compare battery voltage/current/power for internal consistency.

Usage:
  python3 scanner13.py <host> [port] [device_id]

No Modbus writes are performed.
