2x 6P16S indeed, with 2 BMSs. They're 60Ah S168 cells, green wrapped cylindrical LiFePO4. One bank measures about 38x35x100cm (15″ x 14″ x 40″), plus accessories. I want to clean up my build before I'm comfortable posting about it, I'll probably make a post in the show and tell forum once I'm...

I used to use the JK BMS adapter, that would show all the voltage values in SA as well, it's a bit more accurate with the SoC calculation. But "inverter values" does work, if you just want to see the pack voltage, current and SoC. Seeing as your BMS does communicate with the inverter, you can...

I'm on HMI 1001-c020 MAIN Ver 2005-f098-1807. Since I'm not aware of a public changelog, I'm not sure if or whether there are any significant differences. I use Solar Assistant to monitor and make changes, since that integrates to Home Assistant quite nicely. It's also easier to do all the...

You already have communications working, since the inverter recognizes the values sent to it. There isn't really much sense in setting the BMS limit to 55.2V, this way it would disconnect when you go over that value, which might happen when you're charging. Think of the BMS as a line of defence...

You can set those in your inverter under Battery settings, page batt set3, the same that is in your picture with the name "using Voltage.jpg", which you have already done. These are the limits that the BMS sets, it just shows what the BMS limits are. Actual charging and discharging is limited...

Seems to work better, it connects every time I restart and is a lot faster with BT connected, the SOC issue is fixed as well. However it still seems to drop the connection to the inverter after 25-35 minutes, even with just 1 BMS connected. For some reason, when 2 BMSs are connected (serial and...

Post #49 in this thread has all the settings and information that you need (the second image with bootloader and partition). And if it still doesn't work, make sure you are flashing the ESP32 correctly.

Have you connected to the Wifi network created by the ESP32? You'll need to connect to it, then enter your Wifi network credentials. After that your router will assign an IP address to the ESP32, then you can access it with that address. The 192.168.4.1 only works within the ESP32 Wifi network...

Li-LV gives no information to the inverter. Pylon only works like every 5th restart, Seplos works every restart. The serial interface of the second BMS doesn't send correct information, the RS485 module in it is faulty, but I haven't had the chance to get it replaced under warranty yet. BT has...

Exactly, only when both batteries are connectors. When it is UART only, everything is correct. The Ah number is also correct on both, it's just the SOC that's messed up on UART when both are connected.

After I restart the ESP32, I get this: InvertorConnected CAN Receive Id0x305 CAN Receive Msg0-0-0-0-0-0-0-0 It stays connected up to an hour this way, based on Solar Assistant data (since the battery SOC will display as 100% when connected due to the UART BMS displaying 360%)., after that it...

What do you mean exactly? Are any of these pictures any help? Or do you need something else?

Both Pylontech and Seplos seem to work intermittently, occasionally the inverter won't recognize the protocols. Picture with Pylontech protcol and lithium mode 00 attached. The current is half of what the inverter receives, so it's only reported from 1 BMS, the one connected with UART. However...

That fixes most of the issues with the BT connected BMS (except for temp, but that might be a BMS issue, since the external sensor report 0C, while it's actually 25C), however the SOC on the UART connected battery is still messed up. Is this one sufficient or do you need the photo from the...

I haven't had any W31 or F31 errors, so no problems on that front. However, the module doesn't work with both a UART and BT connection for me. No issues with the UART, BT only doesn't show charging, discharging or SOC. Both together it sets the UART connected BMSs SOC to 360% and doesn't show...
