The meter will overwrite the oldest load profile data first in the event that all memory allocated
to load profiling is consumed. The meter will generate a memory full event for the first time
data is overwritten without subsequent intervention to free up memory. The memory full event
is classified as a critical priority event by default. The meter will send a notification message via
the AMI signal.

The SGM3000 Series meters support Time of Use (TOU) metering.
The meters support multiple TOU registers, daily time periods, day types, seasons, and holiday

an individual rate, the user must provide the start date and time and price for the rate.
