Description
Displays the real-time energy savings based on the
following calculation:
The (estimated) power consumption during the
commercial power supply operation - the input power
to the inverter
The energy saving effect by the inverter operation can
be checked in real time.
Displays the energy savings per hour, which is the
average for the period set in the parameter (30min to
40 days).
Monitored values can be periodically obtained using
analog outputs and communication. The obtained data
is useful for statistical analysis and forecasts.
Displays the cumulative energy savings.
The cumulative energy savings can be checked.
The cumulative energy savings can be cleared to zero
or can be set cumulative. It is useful to check the
energy saving effect for a particular operation,
including a test operation.
Annual energy savings can be estimated with the
cumulative energy saving during an inverter operation
and an operating time. Set an annual operating time
ratio (annual operating ratio) in the parameter.
The energy savings is automatically calculated inside
the inverter.
Set Pr. 896 = 9999, Pr. 897 = 0 to 1000h.
4) Average power
saving rate.
Set Pr. 895 = 0 or 1.
Set Pr. 896 = 0 to 500.
5) Average power cost
savings
Set Pr. 899 = 0 to 100%.
9) Annual power cost
savings
Set Pr. 896 = 0 to 500.
Remarks
Monitoring is
available when
Pr. 52 or Pr. 54 =
"50."
Monitoring is
available when
Pr. 52 = "51."
