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) 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 settings" field on the "Input 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 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 do 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. If the FB input is configured to measure production then a short label "counts prod."
appears above the measured value.
Erase statistics – 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 the relationship: 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 the 5 main summary data (production, surplus energy, self-consumption, consumption in
normal and low tariff) in bars for the last 7 days. Double click on the bar to view the day in the daily
statistics.
Monthly statistics:
Production chart - displays summary data on production (prodsurplus energy) in the last 31
days.
Consumption chart - displays summary data on consumption (self-consumption, consumption in
normal and low tariff) in the last 31 days.
Export- exports monthly statistics to a *.csv file that can be opened e.g. in MS-Excel. For first 7 days
daily output and FB input states are exported from weekly stats.
Import - imports monthly statistics from the *.csv file. The file must contain monthly statistics stored
in WATTconfig Mx, M, or ECO. This feature can transfer statistics from another device. The daily input
and output states are not imported. This import replaces internal statistics.
Note:
The monthly statistics can't show detail of a day as in the case of weekly statistics, details are stored only
for the last 7 days.
Yearly statistics:
Production chart – displays summary data on production (prodsurplus energy) in the last 12
months.
Consumption chart – displays summary data on consumption (self-consumption, consumption in
normal and low tariff) in the last 12 months.
