zendure SolarFlow 2400 AC

[acoustic hedge]

Hi all,

Is there anyone that is using the SolarFlow 2400 AC with haos??

If so, what can you controll and what sensors are readable??

Because i can't see it in the documentation.

[astral blade]

None

There is no integration for Zendure products with homeassistant. This is a community feature made available through hacs

There is no local control available with their devices so it's kinda just using whatever is exposed by the cloud with control options strapped onto the default input/output modes

https://github.com/Zendure/Zendure-HA

More can be read within their documentation

In short you get about most things you see within the app. A bit more in terms of battery controls and i sights, but none of their built in modes to switch.

Modern Zendure devices have a local API. One of our Dutch friends created this: https://github.com/Gielz1986/Zendure-HA-zenSDK

You'll likely need to ranslate but it works perfect! Have fun 🙂

[acoustic hedge]

You use it??

[manic moss]

Yes. And currently working on a modified version to support multiple batteries together.

[acoustic hedge]

can you set the loading wattage and stuff like that?

or can you share some screens of your sensors and stuff

Thanks for the reminder. Here is a screenshot of my dashboard currently. Would you like a list of all available sensor or so?

You can translate the Dutch GIT repo easily to English nowadays. Perhaps that helps as well?

[acoustic hedge]

do you mind if i DM you ??

because these are inverters ? do you have the solarflow 2400 ?

[manic moss]

I have 3x 800pro. They offer the same API as the 2400AC.

• As an extra they also have 4 MPPT trackers each. Which I prefer.
• Downside is the max 800W discharging / 1000W charging over AC. But that’s ok. With 3x 800W I have enough power to cover my home.

And yes feel free to DM. Al though for knowledge sharing I wouldn’t mind to keep the chat in a public channel.

[acoustic hedge]

The Solarflow 2400 doesnt have mppt? Or am i mistaking

[manic moss]

Correct. It can only charge itself over AC.

[acoustic hedge]

To bad there is no real information of what you can do with that one in HAOS

[astral blade]

You can always ask the ones maintaining the integration to help you figure out such things

generally most cloud independent functionalities are available

[manic moss]

Here you can find documentation about the API: https://github.com/Zendure/zenSDK

[manic moss]

Can you elaborate a bit?

[acoustic hedge]

i've sent an email but they do'n respond so.. thats why i'm trying to see with other haos users 😉

[acoustic hedge]

i actually want to read all the connected batteries, SOC and temp (if possible) and set the charge and inverter wattage.

i want to charge with the same wattage that i overproduce with my solar panels

And invert only what i consume from the grid.

The goal is to balance so that i don't put solar and battery energy to the grid but also don't use energy from the grid to charge the battery.

but in order to do that, i need to be able to read de SOC and write the charge and inverter values

[astral blade]

I'm not sure where you would seem to send an email, zendure-ha is a community product and they are available through their GitHub.

[astral blade]

They have something built in for that

I'm certain it won't be perfectly like local Shelly to device communication but surely better than going the cloud way

[acoustic hedge]

ok, but is it possible to get that info in HAOS. thats my question, what sensors are available for SolarFlow 2400 AC? read and/or write sensors.

[astral blade]

That's what the integration is for

@it

@acoustic hedge All you describe is possible.

In Home-assistant you need to define a sensor that gives you the grid power (negative for feed in). The typical term I’m used to for this is “P1 meter”.

I’m using a Shelly PRO 3PM for this.

You need to put the P1 sensor here: https://github.com/Gielz1986/Zendure-HA-zenSDK/blob/19fb93bac6c26e3d0b654612387e64dd569e2b0f/README.md?plain=1#L37

And here is a list of sensors to get the data from the batteries and inverter: https://github.com/Gielz1986/Zendure-HA-zenSDK/blob/19fb93bac6c26e3d0b654612387e64dd569e2b0f/Configuration.yaml#L123

And here is the logic used for calculating the power to charge/discharge to get to zero grid usage / feed in (in Dutch: NOM / Nul op Meter).
There are 3 options here:

• Only charge the battery with surplus / prevent feed in
• Only discharge the battery to prevent energy consumed from the grid
• Combined. Always try to prevent both.
