Describe the bug

integration will no longer connect and i see this:

Failed setup, will retry: Modbus error: Modbus Error: [Input/Output] Request cancelled outside pymodbus

Expected behavior

after a restart of the system i am expecting the integration to connect as it always had been

Screenshots

Diagnostic File

i don't see a "download diagnostics"

There should be more logs, I need to see all of them especially the parts where it it tries to read the inverter data up through the coordinator false message.

You can also try turning off the "Auto-Detect Additional Entities" option.

[Menz01]

hmmmm just disabling "auto detect additional entities" seems to have fixed the issue. i wonder why that is?

[WillCodeForCats]

Your inverters may have had a firmware update recently.

SolarEdge changed the way they handle unsupported functions in some firmware versions. The best way is to return an "unsupported" response, which is what older firmware does like the version my inverters are at (0004.0014.0229). Either some or all newer versions change that behavior can changed to stop responding and time out or fail connection instead of returning the "unsupported" response.

I've tried several ways to work around this but based on what happened with your inverters it's still not good enough for the best user experience.

Many releases ago the default for "Auto-Detect Additional Entities" was enabled. I changed the default to disabled because of this issue for new users. But if you were using the integration before the default changed the old default would continue, so you might not know why it suddenly is having a problem when it doesn't look like anything changed.

[Menz01]

thank you

Seems like there's been firmware pushed out that causes issues with Modbus TCP - my inverter went offline overnight.

I was on 4.22.44. I am now on 4.23.36, which isn't even listed on the SE Website

At 06:43 the connection failed and no amount of Integration or Home Assistant restarts would bring it back.

The integrations failed to connect:

Probes showed no response at all from the inverter on Port 1502, I had to physically connect to the inverter from my phone and go into the SE App to diagnose.

It showed that Modbus TCP was still enabled.

However, once I had set Modbus TCP to disabled, than then back to Enabled it immediately started accepting connections again - hopefully this will help someone else!

I have the same problem and the same firmware.
But I do not have access to the SE App (only monitoring is possible).

Turning off/on the inverter did not work.

I raised a ticket to the SolarEdge support, maybe other can to the same, if they face the same issue!

[cyberkryten]

You can access the inverter settings by moving the momentary switch to the P side and then connecting to the Wifi access point that appears.

Then look at the Wifi settings to see the 'Default Gateway' given. Usually this seems to be 172.16.0.1 so put that address into a web browser on the device that is connected and you'll be able to access the settings from there.

You want Site Communication then Modbus TCP. Change it to Disabled, wait a minute and change it back to Enabled.

Don't touch anything else! All risks your own, etc etc

Mine stopped working today too i'm going to have to work out a way to automatically disable and enable ethernet on this solar edge inverter. Annoying that solar edge broke it

[jluc2808]

got some connection failed too, since the 24/07 (after an upgrade of the inverter)

I just wanted to drop in and report that disabling and re-enabling the Modbus TCP setting in the inverter settings > Site Communications (SetApp) worked for me.

I've been using this custom integration for about 3 years now.

I updated my inverter firmware to 4.2.36 in early July. Home Assistant had been reporting quite frequent modbus disconnnections, but they always cleared and reconnected.

Until last night.

I updated Home Assistant Core to 2025.7.4 yesterday morning and at 2133 last night the modbus connection dropped and wouldn't reconnect. I found this issue and tried unchecking the "Auto-Detect Additional Entities" box but that made no difference. I left it for the night knowing that today was going to be a good solar day and the SE app would suffice for now.

This morning I went into the inverter settings in SetApp > Site Communication, for anyone looking, disabled Modbus TCP, waited 30 seconds and enabled it again. Home Assistant picked up the connection again almost instantly.

I'll continue to monitor, but hopefully we have a temporary fix until the repo owner can implement a fix.

I'm no coder by the way, but if there's anything I can do to help, let me know. Our home energy use is heavily reliant on having the level of control this custom integration gives us so I wouldn't want to see it fall over completely.
