+====== Inverters ======
+It shows inverter's particular values.
+=== Time period of data selected ===
+Data export can be generated for daily, monthly or annual time period. Daily time period contains all incoming samples of selected value in a day. Monthly and annual time period show one sample of each value and day. Time period stipulates the day (days) to be exported.
+{{:sim:portal:graph:previous.png?nolink&}}button **Previous** shifts time period one day backward. With daily time period we can click on back arrow and it shows the previous day etc.\\
+{{:sim:portal:graph:up.png?nolink&}}button **Scope ** chooses longer time period. With daily time period we can click on button Scope and the graph shows monthly period. With monthly time period we can click on button Scope and the graph shows annual period.\\
+{{:sim:portal:graph:next.png?nolink&}}button **Next** shifts time period one day forward. With daily time period we can click on forward arrow and it shows the next day etc.
+    *
+**Since**  the first day of the time period
+    *
+**Until**  the last day of the time period. If it is only one day time period the date in Since and Until boxes is the same.
+    *
+**Today**  when you click here the current date is filled in automatically in the Since and Until boxes.
+    *
+**Month**  (e.g. January, February…) when you click here the boxes Since the first day of that month and Until the last day of that month are filled in automatically.
+    *
+**Year**  ( 2010, 2011…) when you click here the boxes Since the first day of that year and Until the last day of that year are filled in automatically .

+=== Export of data into CSV format ===
+----
+Export enables further work with data. Exported file is ready to be used in MS Excel application which offers comfortable work with files in CSV format. You can use the exported data for calculations or creating graphs. You can choose CSV separator and decimal separator for exporting data into CSV file.
+Select a sensor (sensors) whose data you want to export. In daily time period it shows all incoming data ( depends on set interval, minimum 5 min). With interval longer than 2 days you will see arithmetical average of incoming data per 60 min. With interval longer than 30 days you will see arithmetical average of incoming data per 24 hours.
+== Export of average values ==
+In daily time period it shows all incoming data ( depends on a set interval, minimum 5 min). With time period longer than 2 days you will get weighted average of incoming data per 60 min. With time period longer than 30 days you will get weighted average of incoming data per 24 hours.
+**Export of a selected value from all inverters**, **Export of selected values from selected inverters.**
+V denním pohledu zobrazuje všechna přijatá data (dle nastaveného intervalu, min. 5 minut). Při intervalu větším než dva dny se data průměrují (pomocí [[http://cs.wikipedia.org/wiki/Aritmetický_průměr|aritmetického průměru]]) z příjatých dat za časový interval 60 minut. Pokud zobrazený interval přesáhne 30 dní, zobrazená data se průměrují (pomocí [[http://cs.wikipedia.org/wiki/Aritmetický_průměr|aritmetického průměru]]) z přijatých za časový interval 24 hodin.
+== Seznam veličin ==
+Fac - frekvence měniče \\ Iac - střídavý proud měniče \\ Ipv - stejnosměrný proud v měniči \\ Pac - výkon na výstupu střídače \\ Tkk - teplota střídače \\ Uac - střídavé napětí v měniči \\ Upv - stejnosměrné napětí v měniči
