Per attached doc is there a way to get this info from modbus? I'll likely have this fault for the next week or so depending on how long it takes for me to find it / my installer to get someone out.

All known inverter sensors with a modbus register are already implemented.

It's possible there are undocumented registers, but someone would need to find them. For more information see: #285

You could just try scanning every possible register and see if anything responds outside of the known ranges.
