You will be asked for a new interval:Fig. 4.2.3.1 – Edit Y Range4.2.4 – Set visualization to current dayThis function shows the current day in the X axys of the chart (from 6:00 AM to 8:00 PM).Use it to quickly reset the visualization to the default one if you manually scrolled/zoomed into the chart.4.2.5 – View AllThis function automatically changes the X and Y axys of the chart in order to perfectly fit the waveform on it.Fig. 4.2.5.1 – Example of “View All” function4.2.6 – Y Axys Scale ModeHere you can choose how the Y axys works:- Fixed The Y axys range is fixed, and depends by the one you defined yourself (see4.2.3)section- Auto-Scale Loose The Y axys range is determined by the minimum and maximum values,with a small gap on top and bottom.- Auto-Scale Exact The Y axys range is determined by the minimum and maximum values,with no gap on top and bottom.- Scope Chart The Y axys range follows the waveform. A small gap is left on top or bottom.- Strip Chart The Y axys range follows the waveform. No gap is left on top or bottom.4.2.7 – Printer Setup / PrintThese are standard dialog boxes that allow to set up a printer and print the selected chart.5 - StatistitcsFrom the menu on the top, select “Statistics” to open this section:Fig. 5.1 – Statistics Menu“Today Energy” and “Power” are the charts that you can see in the main application window (see section 4); if you close them, you can open them again by clicking on these entries.5.1 – Alarms / WarningsThis is a list of past alarms and warnings reported by a single inverter.From the combo box on the bottom, select the inverter you want to analyze and the program will start loading data from it:Fig. 5.1.1 – Loading alarms and warningsThis operation may take a few seconds, according to the total number of events stored in the inverter. Once this operation is completed (you can abort it any time you want by pressing the “Stop” button), you will be shown the list of alarms and warnings:Fig. 5.1.2 – Alarms / WarningsUse the “Alarms” and “Warnings” buttons (located on the bottom) to switch between the two tables. You can sort these lists by clicking on the column titles in the table’s header.By using the “Export” button you can also save these lists in different formats:- .txt A simple text file that can be opened with any editor.- .xls A TAB separated file that can be opened with any version of Excel.- .csv Another type of file that can be opened with various applications (Excelincluded).NOTE: you can save these files in 2 ways: european or american. The firstone uses the character “,” as separator for decimal digits, while the secondone uses the character “.”.5.2 – Recent Power StatisticsInverters store a sample of output power once every 10 seconds. This allows around 2 days of detailed analysis.By using the “Recent Power Statistics” function, you can download this information on your PC.Be aware that this operation will take around 6 minutes to complete, since there are many values to download.Once completed, you can export the values to csv or excel files.5.3 – System StatisticsThis function generates a chart with the system statistics.Fig. 5.2.1 – System StatisticsSelect, on the left side, the measurements you want to appear on the chart; daily energy can be shown either with a scatter or an histogram chart.Then, select the time period on the right: either select a single day or look for a particular interval. Press “Ok”, and the program will search for the required information, then a chart will be shown.5.3.1 – Statistics ResultsThe chart generated by the statistics functions can contain more waveform:Fig. 5.2.1.1 – Example of System StatisticsIf you right click on the chart, you will see two new menus: “Select Waveform” and “Show Waveform”.“Select Waveform” let you choose which one of the waveforms is currently selected. It is necessary to select a waveform to make measurements (using the cursors, see section 4.2.2), change the units in the Y axys and the title of the chart, and finally to export it (only the selected waveform can be exported when you choose the “Export Chart” function, see section 4.2.1).“Show Waveform” let you hide and show the single waveforms shown in the chart.NOTE: you will not find any data from the current day in these statistics because they are stored the next day.5.4 – Inverter StatisticsThis feature is similar to “System Statistics” (section 5.2), but only shows data of a single inverter.Fig. 5.3.1 – Inverter StatisticsFirst, select an inverter from the combo box on the top.Then, select on the left side the measurements you want to appear on the chart; daily energy can be shown either with a scatter or an histogram chart.Finally, select the time period on the right: either select a single day or look for a particular interval.Press “Ok”, and the program will search for the required information, then a chart will be shown:Fig. 5.3.2 – Example of Inverter StatisticsThis chart works exacly like the one generated by “System Statistics”: see section 5.2.1 (“Statistics Results”) for more information.5.5 – Store StatisticsAurora Communicator automatically stores daily statistics to files each day at midnight, then clears the charts.This is done to save memory (only information for the current day is shown) and to organize data for the statistics.You can also manually store these files by using “Save and Reset” in the “Statistics” menu.“Save and Reset” saves the current charts to files, then clears all of them (it’s the same thing that is automatically done each day at midnight).5.6 – Opening Chart FilesIt is possible to load chart files that you previously exported by using the “Open Chart File” function. You can load charts in these formats:- .cht- .xls- .csvPlease note that if if you have modified charts files with other applications (for example, you opened an .xls file with Excel and saved it again) you most likely will not be able to open them again with Aurora Communicator!6 – E-MailIt is possible to configure Aurora Communicator in order to send via mail faults or daily reports. To enable this function, check the option under the “E-Mail” menu:6.1 – Configure E-MailSelect this option to set up email addresses and SMTP server.In the section on the left, set up the mail server, using authentication if required.Some SMTP servers also require you to set proper sender name and address.The other two section refer to daily reports and fault reports.Daily reports are sent each day either at a specified time or when inverters are switching off (at the end of the day, due to missing sun).Set up the mailing list by adding each address using the “Add E-Mail” link.Data logs are attached to each daily report, if enabled (see section 7 for more info on Data Logger).Fault reports, on the other hand, are sent immediately when a fault is recognized. Set up the mailing list as for the daily reports. You can also choose to ignore warnings and receive reports only for real faults.7 – Data LoggerData logs are files created daily by Aurora Communicator that store various measurements taken at specified intervals.To enable this function, check the option under the “Data Logger” menu:7.1 – Configure Data LoggerSelect this option to set up measures, folder and interval time for data logger.Mark the measures that you want to appear in the log from the list on the left.Then, you can select the folder where to save the data logger files: for each day, a different file is created. You can also set up the system name that will be reported in the log, the interval between eachmeasurement and the start / end time.8 – SynopticThe synoptic is a simple window that just shows the main system parameters and statistics without any detailed information.This window, called “Plant Display”, can be found under the “Help” menu:9 – Aurora PVI DesktopPower-One’s Desktop product allows inverter owners to monitor performance from anywhere within 300 metres of the units. Ideal for residential and small commercial PV applications, the Desktop features touch screen colour TFT display and can be either wireless or connected.By connecting your Aurora PVI Desktop to a PC via USB cable or Bluetooth it is possible to use Aurora Communicator to perform various tasks from the specific menu:The option “Communication Setup (Bluetooth)” is only enabled if PVI Desktop is not detected via USB: when the device is connected directly via USB and you click on “Aurora PVI Desktop” menu this option will be automatically disabled.9.1 – Firmware UpgradeUse this option to check for new firmware updates and to download them into your PVI Desktop.If your device is properly detected, you will see on the left panel some information about it.If no device is detected, you will see this message:Proceeding in offline mode allows you to download new firmwares from the web.In this case you can:•Check that the USB cable is properly connected and that the PVI Desktop is switched on (if you have just switched it on, wait for the starting sequence to end)•Close Aurora Communicator, disconnect and reconnect the USB cable, then run again Aurora Communicator•If you are using a Bluetooth connection, check the communication settings in the specific menu (be sure to select the correct communication port):9.1.1 – Web UpdateWith this option you can check for new firmwares on the web or download previous releases.Make sure that your internet connection is active and press the “Web Update” button in the “Aurora PVI Desktop Firmware Upgrade” window.The combo box will show the list of firmware revisions which have been officially released: the latest one should be automatically selected.Press the “Update” button to download the selected firmware and automatically send it to the PVI Desktop.Instead, use the “Download” button if you just want to download it to a folder in your PC and upgrade later.9.1.2 – UpdateOnce you have loaded a file, press the “Update” button to upgrade the PVI Desktop. You do not need this operation if you are using the “Web Update” function (it will start automatically).The whole operation could take several minutes to complete.9.1.3 – Change RevisionWith this option you can activate a newly downloaded firmware or restore a previous version.Press the “Change Revision” button to open a list of available firmwares, select one and then press “Ok” to start the procedure.9.2 – Data LoggingPVI Desktop acquires, for each monitored inverter, statistics about daily energy and power. With this function you can download them to your PC and either view or export them to a file.In the top panel, “System” you can download data about the whole plant, while in the bottom one you can find data about single Inverters.Use the “Import Data” buttons (either for the system or a selected inverter from the list) to show the files available:Just select the files you want from the list, browse the destination folder where you want to store them and press “Download”. The download window will appear:To delete files follow the same procedure: just press the “Delete Data” button and select the files you want to remove from the list, then press “Delete”.NOTE: To use the “Delete Data” buttons you need to upgrade the PVI Desktop to at least version 6.18.Once you have downloaded the files on your PC, you can view them in Communicator: press the “Open File” button and select a file. Files which contain daily power curves are renamed with the date of when they have been acquired by the PVI Desktop, while the one containing the produced energy (day by day) is called SYSTEM_DATA.XML (or SNXXXXXX_DATA.XML for single inverters).The one above is a typical Communicator chart, which can be exported using the top left button (Save). See section 4 for more information about these charts.9.3 – Start Screen CalibrationShould your PVI Desktop become unusable due to wrong screen calibrations, you can run the calibration procedure by using this option from the Aurora PVI Desktop menu.。
