Daily statistics are reset every time just after midnight, i.e. at 0:00 A.M. At the same time, daily
values from the just finished day are moved into history. When you change the date in the
controller you may cause irreversible deletion of stored history!
Real time chart (since firmware version 3.0):
Up to 7 rows can be selected in this line chart, which can display power or temperature curves. You can select a
time base of acquiring values from 1 second to 10 minutes. The maximum number of points on the time axis of
the chart is 144 (when selecting a ten-minute period it corresponds to 1 day). The chart data are not stored in a
non-volatile EEPROM, and therefore after a reset, or if there is a power failure, the data is deleted. The data
will also be erased each time you reconfigure this chart.
Time base - configure the period of reading values into the chart.
Series 1-7 - dropdown menus configure the input or output to be loaded into the corresponding chart
series.
Export - exports chart data to a * .csv file that can be opened e.g. in MS-Excel.
Daily statistics:
Show for day –select the date for which to view daily statistics. You can display them for current date
and last 7 days.
Phase Lx–displays information about the surplus (excess) energy, normal and low price energy tariff as
well as (optionally) PV-production, when counted with a FB input, in the current or selected day.
Total L1+L2+L3 – displays summary data from all three phases. The calculation of these data depends
on the selected control mode -the "Control mode" field on the Other settings tab:
a.
Each phase independently – summary data are simply the sum of the fields from all 3 phases
b.
Sum of all phases – summary data are updated continuously from immediate results.
In this
control mode summary data are not the simple sum of the displayed values in each phase
(in one phase the surplus energy may cover consumption in different phase, etc.).
Daily output status- displays the assumed or really measured amount of energy supplied to each load
in the current or selected day.
Since the statistics are reset every time just after midnight, these
values will not correspond with the values in the fields "Supplied energy"
(reset of those fields is
generally done at different time).
Daily FB input status – displays the measured energy at corresponding FB input in the current or
selected day.
Erase internal stats – use this button to delete all statistics stored in the built-in EEPROM memory.
Confirmation dialog will be shown first.
Charts – they show a graphical interpretation of the daily statistics on production and consumption.
Charts in each phase indicate the part of corresponding summary data (pie slice or part of the bar).
The self-consumption value is calculated from this formula:
self-consumption = production – surplus
energy
. Self-consumption values are not available unless the displayed production value is bigger than
measured surplus energy value.
Note
: For very small energy values (typically immediately after resetting statistics after midnight) internal
rounding to 0.01kWh is significant for displaying the charts .In these cases, pie charts may not be displayed
absolutely correctly.
Weekly statistics:
Chart -shows the5 main summary data (production, surplus energy, self-consumption, consumption in
normal and low tariff) in bars for the last 7days. Double click on the bar to view the day in the daily
statistics.
