That line from the vertiv manual is so cryptic.
If the there isn’t a standard set of registers for this purpose then there must
be a specific AC meter it supports. I don’t see one on the listed accessories
in the literature though.
Meanwhile the same manual has explicit instructions for
There are modbus libraries in at least "C" to read devices... I read
the modbus info from our morningstar controllers...

I've never used modbus. I'm looking at AC usage meters that support modbus
over RS-485. And the controller on my Vertiv rectifier says
Modbus is an ancient serial protocol to pass values back and forth. It’s very
