Solar edge integration: some entities no longer update

Configuration
1

SolarEdgeMulti integration. I have been using the SolarEdge integration for a few years now in combination with Home Assistant. For a few months now, these two entities are no longer updated (the other entities are updated).

  • sensor.solaredge_m1_exported_a_kwh
  • sensor.solaredge_m1_imported_a_kwh

In the logging of Home Assistant I see these types of messages:

  • Error fetching solaredge data: Error updating modbus data: unpack requires a buffer of 2 bytes
  • Error fetching solaredge data: Error updating modbus data: unpack requires a buffer of 4 bytes

It seems that the integration and the inverter are no longer aligned (mismatch between registers).

Some articles I have read suggest switching to the multi-integration. Is that a good idea and would that indeed solve my issue, or is something else going on?

My current setup is as follows:

  • Type inverter se3000h, CPU-versie (firmware) = 4.21.23
  • SolarEdge integration version 2.0.3
  • HA-core version 2025.3.

As the author I do recommend trying my integration, it is well tested by many users and has fewer open issues. I’m also more responsive to support it.

hello
I don’t understand why , but i have your solaredge installed but the version is 3.04
All my HA is correctly updated, i think…
How do an update to the last version?
Thanks

HACS should show updates.

If you installed manually you also have to install the latest update manually.

Thanks for your response. Ok, I’ll switch to ‘your integration’. Question about the best approach. As I think about it now: install multi integration next to the ‘existing old integration’. See if everything works. Then remove the old integration. Is this indeed a good approach, or better to do it differently?

You will need to disable the other one first: it’s not updated for current version of Home Assistant and pymodbus library, so loading it will break newer integrations that are up to date.

Ok, so:

  1. disable old
  2. install and configure new
  3. check if new is ok
  4. delete old
  5. be happy :wink:

Correct?

I did it and numbers are coming in. A completely different set of entities than I had before. I don’t quite understand them and have been looking for an explanation of the entities for a while, but have not yet found a clear description.

For the energy dashboard in HA I am looking for the instantaneous generated energy. Which entity is that, I do not see it, not even with the disabled entities? I assume that AC energy is the cumulative value of the energy that I have returned to the grid, is that correct?

Maybe I am completely on the wrong track. Please give me some direction or reference to some documentation in this area. As indicated, I have been looking for quite some time, but have not found it yet.

AC Energy sensor on the inverter is energy produced by the solar panels.

Import and export energy would have to come from a meter, since the inverter only knows how much energy it generated from solar.

This is AC Power in Watts. This is my energy dashboard settings:

However if you have a battery then this value from the inverter probably need to be templated to adjust for battery power, but I don’t personally have batteries to help with that in detail. The discussion on battery templates in the links would help with that.

Thanks again for your information.

We have almost the same configuration of the energy dashboard.

If I look at the graph of ‘AC energy’, it must be the cumulative value of the generated energy. So the energy dashboard will have some logic to show the distribution over the day.

AC power should then be the instantaneous power generated by the solar panels, which makes sens if I look at the graph.

Interesting what you say about the battery and the need of templating some of the values. In a few weeks we will get a battery and that will become relevant. We are doing it step by step. By then I will delve into the discussions about this.
