Integration Solar inverter huawei 2000L

JayVee · December 13, 2021, 11:06am

I’m completely new to the setup. I would like to have both FusionSolar and HomeAssistant connected to the inverter via LAN. Is that possible? Which versions of the firmware make that possible?

I currently have V100R001C00SPC119 for my dongles and V200R001C00SPC109 for the inverters. I don’t know about the battery, it’s currently offline for some reason.

(Also, did anyone compile a guide for this somewhere? This topic has a lot of history of which some parts are probably deprecated now, others not, different firmware versions have been used, … Difficult to understand what the current go-to situation should be, but that may just be me of course!)

it’s possible, I have it that way.
Just setup normally for the fusion solar, then setup the hacs plugin. Use slave option when configuring for hacs.
I have these firmwares:
V100R001C00SPC123 for dongle and V100R001C00SPC139 for inverter.

Something is going wrong! XDDD

JayVee · December 17, 2021, 10:38am

Thanks for getting me those versions! Now I can tell my installer to upgrade to those specific ones.
Did you have to enable the port through the android app for this setup, or is the port open by default with these versions?

andro1 · December 17, 2021, 12:31pm

it is open by default on these versions. On the latest one for the dongle it didn’t worked for me, probably because of the port ( I didn’t know you can open it manually), so I downgraded to …spc123 and worked again. (previously I was on spc 122)

Here you have a guide:
https://forum.huawei.com/enterprise/en/modbus-tcp-guide/thread/789585-100027
(it was also in this thread)
It’s possible to enable this feature (as this is inverter setting) even with inverter ver SPC139 and dongle SPC123 and then upgrade to 124 and it will just work.
Remember to have newest FusionSolar Android APP.

Good

This representation as you have done ?, Could you pass the code from the diagram on the left?

Today my inverter was plugged to grid, but so far without panels connected (icy roof, waiting for better weather). Meanwhile I am trying to set it up with HA already. So far no success.

My HA IP is 192.168.10.10, inverter via dongle is 192.168.10.60, same wireless network, dongle is pingable from HA terminal:

In configuration.yaml I have:

- platform: huawei_solar
  host: 192.168.10.60
  optimizers: false
  battery: false
  slave: 1

and in logs after rebooting

021-12-22 13:10:37 ERROR (MainThread) [huawei_solar.huawei_solar] failed to connect to device, is the host correct?
NoneType: None
2021-12-22 13:10:37 ERROR (MainThread) [custom_components.huawei_solar.sensor] could not connect to Huawei inverter: failed to connect to device, is the host correct?

My inverter firmware ends with SPC135 according to FusionSolar mobile app. No idea how to check dongle firmware. In fusion solar app on devices tab I have two devices - inverter as first and below something called hardware key, but this one doesn’t have any details after clicking.

What am I doing wrong?

EDIT:
I logged via https://eu5.fusionsolar.huawei.com/ and I see dongle firmware ends with SPC119 which from my information is too old. Starting to search how to update it.

If you have an installer account just follow this:
https://skyboo.net/2021/09/how-to-do-a-firmware-upgrade-using-fusionsolar/

Edit:
Just a side note I’d like to share with you guys for your information…
Today I’ve discovered new modbus command which can be used for obtaining SUN2000 inverter software version using dongle

I’ve implemented it in my GitHub - manio/hard: hard (home automation rust-daemon). Here are the values which can be obtained:

I think you can ask @Emilv2 to add this support to the integration if you find it valuable feature.

Gutek · December 22, 2021, 10:15pm

Dongle updated to SPC124. Still problems, but new error in logs.

@Gutek
Are you sure you have modbus tcp port enabled in the inverter config?
Look about 15d back this thread:

I had the same problem…

Gutek · December 23, 2021, 8:55am

Thanks, works!

manio · December 25, 2021, 5:35pm

Hi Guys,
Huawei is currently doing maintenance and the FusionSolar cloud is not accessible (in EU).
The side effect of this is that the dongle cannot connect and it’s thinking that a restart would help. As the result it is constantly restarting (ethernet link down/link up) about every 5 minutes which is leading to interruption with our Modbus/TCP readings…

It would be great if the dongle could ignore this and still work without rebooting itself…

Do you know some setting/way to achieve this?

Taziff · December 25, 2021, 7:59pm

Hello everyone, I have problem with this:

My total yeld is 1660kWh. Why grid_exported_energy and grid_accumulated_energy is so big?

ligeza · December 25, 2021, 8:33pm

Do you have smart meter connected to inverter?

Taziff · December 25, 2021, 8:55pm

No, I dont have.

ligeza · December 25, 2021, 9:04pm

So it’s correct. You will not have this values, they are only available when smart meter is connected to inverter.

In binary, 2147483647 is 01111111111111111111111111111111 and it’s the biggest positive number that will fit in 32 bits when using the “two’s complement” notation – the way of representing numbers that allows for negative values.

Taziff · December 25, 2021, 9:13pm

Oh, I understand.
In this situation which value I need to use in energy tab to show pv production?

ligeza · December 25, 2021, 9:26pm

Solar production: total_yield
