I believe the modbus spec is pretty standard now across the range. Just make sure your installer updates the firmware to the latest before they leave and you should be good to go. Worst case we might need to add a new profile for the H1-11.4US |

I am looking at getting a H1-11.4-US inverter and would like to monitor it with Modbus:

The inverter itself, despite being called "H1" looks considerably different from the non-US H1 inverters. Do they all work the same from a Modbus perspective?
From the manual it looks like there actually may be 5? RS485 interfaces. The A1 and B1 pins are labeled Fox Hub, and since I don't have a hub I assume those would be the best ones to connect my RS485 interface.
