@gimme_power, can I buy you a beer? Connecting the CAN port made a world of difference. The BMS did some funky things with the SOCs and charging when I connected the batteries but it seems to have balanced itself out. The two batteries have the same SOC, and the inverter reads the batteries' data rather than guesstimates it. @jumper, thank you for your input on this too. I couldn't change the inverter's BMS protocol because SA is using the RS485 port.

Cool. I'll check this out later. I found the cables with the packaging so I can connect the CAN if I don't come right with the inverter settings. Let's hope this gets me one step closer. Appreciate the input.

This is so obvious in hindsight. Thank you! I just assumed the RJ45 cable was the right one. I need to go through the packaging to see if I have the cables. If I don't, what do you call this cable? Can you suggest a decent place to by from in Joburg or online? Thanks again for your input and time!

I appreciate the input. Thank you. I've got a few things to consider and rule out any problems with the setup. @jumper's input has opened a few options for me to consider. I saw your open heart surgery posts. Good luck! One thing I couldn't figure out is how to turn the battery off. Can you share how, please. Do you just turn off the breaker and wait?

It looks like this is the problem. The Li-BMS shows zero values for everything. I wish there was a test or clear sign that everything's connected and functioning as expected in both the Battery Information

Thank you, I'll check this when I get home later. It has always shown as 200Ah so I'm not sure if the inverter is set up correctly 🤦‍♂️ This is what is reported by Solar Assistant. The battery capacity is editable I'm learning my lesson for not doing my homework and ending up with a fly-by-night installer 😔

The problem with SD cards is they're not made for the frequency of reads and writes that HA performs. Particularly if you implement MQTT with multiple updates per second. It will work but you're likely to experience failure just as you get everything working. Murphy is our friend, right 😆 Also, make sure to backup regularly and test them if this becomes something you and your family rely on. I use this: https://github.com/sabeechen/hassio-google-drive-backup

Are you referring to this post? Have you had any luck figuring the difference out?

Thanks for the input. I appreciate. I've given this a go but I don't know how to check if the batteries are communicating with each other. Do you know test/check this?

Good luck! There's nothing more satisfying than seeing things "just work". For the hardware, it doesn't have to be anything special but don't run HA off an SD card. I also recommend running Home Assistant OS. It simplifies a lot. When you get your hands dirty, take some time to RTFM. I went in with the curse of knowledge assuming how things would work and lost a lot of time redoing stuff. There are also loads of great add ons and integrations that do the bulk of the heavy lifting.

Hello Everyone I'm looking for some help on how ro set up and test the communication between two Averge batteries. I was reading the manual and saw the set up from my installer didn't match the instructions but now I suspect I've broken something that probably didn't need to be fixed. My batteries have a significantly different state of charge as you can see from the SOC lights. Is there anything else I should look out for? The batteries are connected to an 8kVA Deye inverter if it's of any importance. I appreciate it! Battery 1 Battery 2 The Manual

Hey Everyone. A few months ago, we had a power issue in our area. Eskom supplied 280v plus and the frequency was 0hz. Since this issue was resolved, we experience multiple drops per day. My simpleton mind thinks the current effectively becomes DC if the poles stop switching. Is this correct? Luckily, my inverter protects my house from this but I suspect it's a sign of a far bigger problem with the electricity supply. Does anyone know what causes this? I appreciate any insight!

Thank you for the response, @Patrick OReilly. The graphs come from the Raspbery Pi connected to my inverter running an application called Solar Assistant. The terminology that you're using is the same as what I've seen on the Deye inverter. What you've mentioned here, makes me think that the CT isn't in the correct location - it was all done by the trusty installer. If I uncheck "Limit to Load", I end up with the odd readings and inverted non-essential usage. Things are working for me like this but I realise now that it's not the ideal setup. As things stand, I have good practices running with my setup regarding the high consumers. I have set up automations to turn the geyser on/off according to the day of the week and if I have excess solar production. The downside is that my oven runs directly from the grid and doesn't get supplemented by excess solar. I appreciate your insight on this. I've learnt from it and it's helped me understand the set up better (I've struggled with the user manual).

I've finally found it. Thanks to the response in this post. It appears the integration into Solar Assistant set Limit to Load to false (unchecked). I needed to check this again and all is reporting correctly.

What a fail. Thank you for the heads-up. Please let me know if they're visible now.

Hey Everyone. Hardware: Deye 8kva Inverter Software: Solar Assistant, Home Assistant I've had a new install done and notice that I've been sending power back down the grid. I'm using Solar Assistant and get and set inverter values in Home Assistant via MQTT. When I realised what was happening, I tried to the Solar export when battery full value via MQTT. You can see the change in values since doing that on Thursday night. The only Grid values I see are negative ones if I allow solar selling. And it appears as if the true grid values are now being read as the non-essential values albeit inverted. Does anyone have any clue what I've done here? I have tried to restore the settings and reboot the inverter to no avail. Thank you for your time. Sincerely, I appreciate any assistance with this.
