[BATTERY SUPPORT] Zendure mix 3000/4000 series

[msenft]

Requested battery

Manufacturer: Zendure
Model: SolarFlow Mix 3000 AC+ or SolarFlow Mix 4000 AC+

I am looking into buying 1 of these batteries and wondered if already someone is implementing these

What kind of support are you requesting?

Full control: charging, discharging, and monitoring

Developer documentation

Not sure if this is the actual documentation https://github.com/Zendure/zenSDK/blob/main/docs/openapi.yaml

Documentation access

Publicly available without an account

Known connection methods

• Local network over Ethernet or Wi-Fi
• Modbus TCP
• RS485 / Modbus RTU
• MQTT
• Local HTTP API
• Cloud / Internet API
• Bluetooth, USB, or serial port
• I don't know

Capabilities found in the documentation

• Read the real battery percentage — SOC (battery_soc)
• Read actual charging and discharging power in W (battery_power)
• Command a specific charging power (apply_setpoint +W)
• Command a specific discharging power (apply_setpoint -W)
• Stop charging and discharging and remain idle at 0 W (standby)
• Determine the safe maximum charging and discharging power
• Detect when the connection or telemetry is no longer updating
• Enable external control, if the device requires it
• Determine whether commands are temporary or stored in device memory
• I cannot identify these capabilities

Technical references and useful clues

No response

Do you have access to the battery for testing?

No

What would you like to achieve?

I would like to use Omnibattery features like NOM and predictive charging

Confirmations

Hi,

Thanks for opening this battery request. Currently the Zendure mix 3000/4000 is not suported by ZenSDK:

As soon as they make it available we will add it to the integration.

Best regards

Can you do a test for me? Lower both max discharge/charge power to 3900W, then increase it to 4000W, and let me know

[lithoijen]

That is solving the issue i think!

[lithoijen]

Thanks for the superfast service! Tried for all 3 units, now all off them will go above the 2400w!

[ffunes]

Great! There is a fix for the next beta so no manual intervention is needed.

[lithoijen]

Charging now my car. System works perfectly!

Would it be possible to add support for the Zendure SolarFlow 3000 Mix AC+ as well?

I have Omnibattery installed, and it is currently controlling my 3000 Mix. It seems to be working correctly, but the battery itself is not recognized. As a consequence, the maximum charge and discharge power are not reported correctly.
For the SolarFlow 3000 Mix AC+, the maximum charge/discharge power is 3000 W. I assume that most of the other settings and parameters are similar to those of the 4000 Mix AC+.

Below the properties report, let me know if you need any additional information.
