testing RJ45 communication splitter with Growatt SPF inverter

I tested two comms RJ45 splitter or y-adapter with parallel Growatt SPF5000 ES setup and it works like a charm...

Be carful that the Raspi is not only running on SD , I know from the Monitoring of my PV that the SD went broken at least twice over the last 10 Years. Not it is running on an USB-SSD sind 2 Year ... looks better. Currently I have 2x Growatt , if that works with CAN it would be nice to switch from the "WIFI".

changed it a few weeks back to an SSD when the first sd card broke...

Can you please post the wiring of rj45 to rs485 wires?

[@kirkdis]

for that please check your manuals. each manual for the inverter and the battery should clarify the whole wiring based on your communication format
