Hello ,

Been working few days to make my axpert king II work with the daly home storage bms that comes with wnt board built in

I was able to communicate via Lib protocol but can't communicate via PYL protocol.

Anyone had this issue ?

Using 3 5 pins on inverter side and 1 2 on bms side .

Setting bms to voltronicpower rs485 which work with lib only on inverter side but i cant see soc or battery packs on inverter .

I tired voltronicpower protocol on bms with pyl on inverter and getting error 61 .

Change the bms to pylon protocol didnt helped .

Is it a firmware problem , wiring ? Or something else .

Do you have a U2 update file for this model, please?

King II 5 kW models seem to pair with either 19.xx or 44.xx; I don't understand the difference so far.

The latest 19.xx that I have, from October 2024, is 19.21.

The only 44.xx that I have, from July 2023, is 44.33.

If your King II is a Twin model, and/or the display is colour (usually round), then it will require different display (U2) firmware again. Perhaps 20.xx, 52.xx, or 57.xx. That's why I wish everyone asking for firmware would say what their existing firmware version is.
