B.1.16 Module Status Command “ms”:
This command provides specific information about each power inverter module. This command is
not a substitute for the “d” readings command. The “d” readings command provides true voltage
and current readings as seen by the load. The reading information in the module status command
is reading information for the specified power module and may not reflect the actual current or
voltage seen by the external load (depending on the configuration).
