Modbus Wiring Guide for H3-15.0-Smart inverter

[mannyjoher]

Hi all,

I was reading through docs and couldn't find any wiring instructions for the newer h3-15.0-smart inverter. It doesn't have any pinouts as shown like the previous models. It only has meter 485a/b (via an ethernet port) which from reading the docs is not meant to be used.

Pinouts are via Ethernet (and don't seem to match existing ones in the guide):

If anyone could please assist, I'd appreciate it.

Thanks!
