Hi all
Has anyone managed to get these type of inverter / battery into HA, ideally using the wifi interface but other ways also.
Can’t seem to find an integration for these anywhere.
Thanks

Yes. I’ve got this working. It has been bugging me since I got the battery and inverter in 2024, and even more so since adding some solar panels in November(!)
You’ll need a Raspberry Pi (I used a 3A) and a USB to RS485 adapter. I used this one.
You’ll also need the software from https://solar-assistant.io - there’s a free trial. Download the image and install it on an SD card, fire up the Pi and make up a 2-wire cable to your inverter. The RS-485 ports are probably under a cover to the left of the WiFi module:
Leave the 120 Ohm termination setting on the USB adapter off, and connect the wires as shown in the pictures - I’ll have to post these separately as my account here is new and it won’t let me post otherwise.
In SolarAssistant, you’ll want to set up the inverter as an Senergy and select the USB adapter
And that should be it. You’ll see all your stats on the SolarAssistant dashboard:
Then, you just need to integrate with Home Assistant. If you have an MQTT service already running (I have mosquitto in a Docker container) then you can just configure it as a brokered connection through your existing server (in mosquitto.conf):
connection SolarAssistant
address your.ip.address.here

If you’re not doing that, SA have good documentation on how to integrate directly into HA using the MQTT integration.
HA then auto-discovered all my sensors after a restart.
You can then build some nice dashboards in HA, or add the sensors to your Energy Dashboard:
Honestly, SA have been fantastic on tech support and they are well worth the small amount of money needed.
Best of luck.
Here’s the other end of the RS485 cable - I need to finish this off and pass it through the gland so I can replace the cover! Sorry it is a bit blurry
Think this isn’t the latest Dura5 inverter as you’ve a four pin rs485 connector.
I have since managed to get this working on the latest Dura5 inverter see Duracell Dura-i G3 & Dura 5 battery - Third party integrations - Home Assistant Community

Yeah - probably not; I was one of their first UK customers! Glad you got it working - hopefully someone else will find it useful!
When you got yours working, did the native app still work? I’ve got a bexie inverter, which I believe is the same inverter as the Duracell (both a white-labelled oem), also with the 4-pin RS485.
The connection through solar assistant seems OK, it says it’s connected, it can see the battery soc, but the power tab is completely blank. When looking through the native app, it has a communication error with the inverter, and won’t use any battery, only drawing from the grid (it can see the grid usage - both in solar assistant and the native app).
I’m not sure why it’s not working.
For me, yes fully all apps and HA working, Only thing I can suggest is to remove what you’ve added and see what happens from there, if it’s back again give it another go as you may have knocked a different wire and this is why you’ve lost comms, if you revert and still no good I suggest checking all wires pre-existing to ensure good connections, they are super easy to knock.
