SMA SI inverter with Datou boss batteries

[roughneck1918]

Hello, i am very excited to use this on my off-grid setup for powering my home. i have installed everything on my RPI5, which i have installed in a freenove computer case with 4.5" screen, and i have installed the waveshare 2CH-CAN-FD-HAT. i have set up everything in the configuator. my only question... is the wiring, how should i wire everything from the bms and from the inverter into the RPI? should i use any ethernet adapters or is there a diagram/pinout to wire them into the hat? i am VERY new to all this and any help would be great!

You should follow the wiring indicated by your battery brand and your inverter.

Try googling for "Brand Model of Inverter or Battery" RS485 or CAN pinout.

Example: Deye Hybrid Inverter RS485 Pinout

Hi @roughneck1918,
this is the simple overview how to connect it:

The pins of CAN_H/L and RS485_A/B you'll need to check in your manual. There are also some documented on the Wiki:
