Deye inverter to youthpower battery lifepo4

As per the user manual of your battery :

https://www.youth-power.net/downloadfile/20221109194903uYwRFj.pdf

You would need a custom RJ45 cable. 2 options :

* RS485 :
- inverter side : pins 7 & 8
- battery side : pins 2 & 1

Means pin 7 is connected to pin 2 & pin 8 is connected to pin 1. Cable end with pins 7&8 is connected on the RS485 port of the inverter, end with pins 2&1 to the battery

* CAN :
- inverter side : pins 4 & 5
- battery side : pins 3 & 2

Same principle as above but use the CAN ports. Obviously ?

CAN communication would be easier as protocols are set automatically.

If using RS485 you will need to ask the right protocol to use to Youth Power or Deye (well, chance Deye won't know, they can't know the BMS & protocol of all Chinese assemblers ...) or try all of the 16 individually ...

Equalization does not apply to Lifepo4. Only float (53.5v) & absorbtion (54v) but they will be set by the BMS once you set the communication

I check the manual there s nothing about pins anw i linked into can but by hard searching i found protocol of can 00 and for ra485 is 12 right? What is that any explanation and i am asking what s the diff between rs485 and can

Even though these two might seem similar, RS-485 lacks many features that CAN effortlessly is able to deliver. Check out this blog to know!

See RS485 & CAN ports pins assignments page 11 of the battery manual + Appendix I of the deye manual for pins assignments on the inverter ...

Glad you found the right protocol settings but you need the correct pins on the RJ45 cable on both side ?

i guess no need for pin stuff just link into cannor rs485 bcz inside the battery box has 2 cables one for can one for rs485 and it mentioned on one side for inverter one side for battery
