[Bug]: Unable to connect to Inverter SUN2000-10K-MAP0

[robgalea]

Describe the issue

Hi,

I have been previously been using this integration with inverter SUN2000-10K-M1, infact with the help of this integration I found out that the installer supplied the wrong inverter type for the panels I have.

I have since been given the SUN2000-10K-MAP0 however the integration is not connecting to the inverter. I have tried both ports 6607 and 502 as well as both User IDs

Is this expected? This would be ideal to support as to my knowledge this is the new model to support higher amperage panels

Describe your Huawei Solar Setup

Inverter Type: SUN2000-10K-MAP0
Inverter Firmware version: V200R024C00SPC100
sDongle present: Yes

sDongle Connectivitiy: Ethernet
sDongle Firmware: V100R001C00SPC335
Power meter present: three phase
Optimizers Present:No
Battery: None
Huawei Solar integration version: 1.4.1 but also tried version1.5.0a1

How do you connect to the inverter?

Please confirm the following:

• I'm running the latest release of Home Assistant.
• I'm running the latest release of this integration.
• I did not find an existing issue describing this problem.
• I did upload the diagnostics-file that I could retrieve from the 'Devices & Services Page'
• I did upload the relevant debug logs (via 'Enable Debug Logging'-feature or by manually configuring HA logging)

@robgalea Update your sDongle to firmware: V200R022C10SPC110

Hi, @Roving-Ronin tried to do this however V200R022C10SPC110 is not available to download, i instead installed V200R022C10SPC121 but still did not manage to work. The integration specifically works with V200R022C10SPC110 only?

[Roving-Ronin]

It isn't "tied" to using SPC110 it was just that SPC110 with a MAP0 was the version that other people have working with their similiary setup and have confirmed on the Wiki that it works. SPC121 should also work, only time I've seen people give a firmware a thumbs down, is not because it failed to work at all, but more likely its connection dropped in and out a few times a day.

I assume you don't have anything else connecting to the inverters using modbus (and app or even the EV charger, that uses the single modbus connection the dongle supports), and that you have enabled Modbus access (unrestricted is simplest and not to a specific IP) as per the setup instructions?

[robgalea]

I see, from the logs I can see the errors have changed, since the upgrade it now reports the following: Read exception while connecting via ModbusTCP

To my knowledge I am not using modbus for anything else. Currently I only have the inverter and dongle, no EV Charger and the battery system should be arriving next week. Regrading apps, I am only using the phone Fusion Solar app and the Fusion Solar App on home assistant (temporarily) using the Kiosk feature.

The Modbus access is indeed set to unrestricted and the inverter has a static IP configured

[Roving-Ronin]

Have you updated the Modbus firmware also v330 or v335 iirc are available. You update on the SolarFusion portal, same as like updating dongle / inverter, just choose the MBUS option.

Of that doesn't work I'd be swapping the dongle for another and/or flagging with Huawei support to fix.

[robgalea]

I will check what version is the modbus on and revert back

[robgalea]

Hi, so finally got it to work,

In the end I had to change the Start address for automatic address allocation under Dongle parameter setting to 2. In the integration I also set the slave ID to 2 and worked immediately. I guess ID 1 was being hogged by something else.

So just to confirm the integration works well with following firmware versions
Inverter: SUN2000-10K-MAP0 version: V200R024C00SPC100
MBUS version: 335
SDongle version: V200R022C10SPC121

Thanks for all the help
