RS485 Connections to Dual Inverters for Home Assistant
Posted: Fri Oct 11, 2024 12:25 pm
Hi All,
I've a recent install of solar + batteries. Due to the array size we are running dual inverters that should be running in parallel. My installer is coming back for a few snags shortly, and I'd like him to wire in the connections for RS485 to the inverters so that, if I choose at a later date to use Home Assistant, the wiring at that end is already done.
My question is, do the RS485 cable pairs need to wired into each inverter (ie. ending up with 2x RS485 connections to connect into later), or just the inverter set up as the Master?
Thanks!
PS. Sorry if the terminology is incorrect - I'm a newb!
