Thanks a lot

Hello, I'm in a similar situation, I have a 12kW model where there is an RJ45 MODEBUS connector, where I connected pins 7 and 8 but it still doesn't read anything, I tried e.g. Battery SOC with this command: MODBUSR(H, 0x03, Int16)/588 I don't know if this is correct. Can you advise me, thanks

Yes, the battery is set to lithium, but I cant found menu where is "enabled comms" :(

I tried pin 7, 8 and also 1,2 but without any results with read function, You mean pin 3, 4?

But I have these connectors with Modebus, see picture And BMS is connected to battery.

So as I understand I need this splitter https://solar-assistant.io/shop/products/deye_rj45_split

But I have not SolarAssistant system but I have home smart system https://taphome.com/en/support/41123985
