24 Configuring Inverter Settings Introduction RenConnectLite projects define and store configuration settings for specific inverter model/firmware combinations. You can download standard configurations to inverters using predefined RenConnectLite projects or you can change a project s settings and customize an inverter s configuration. Once a project file exists, it can be applied to multiple inverters. RenConnectLite only opens projects that have the file extension *.renl and you can work on only one project at a time in RenConnectLite. You must close any active project before opening another project or creating a new project. NOTICE CORRUPTED CONFIGURATION FILE Only use RenConnectLite to open and edit *.renl files. Use of other software programs to open and edit a*.renl file will corrupt the file and make it unusable for RenConnectLite. Failure to follow these instructions will result in equipment damage. Do not make changes to a project in any tool other than RenConnectLite. If you do, you will no longer be able to open the project in RenConnectLite. You can perform basic tasks quickly by using the icons on the RenConnectLite toolbar at the top of the screen. If the RenConnectLite toolbar does not appear, from the View menu, select Toolbars. Open the Home screen. (If RenConnectLite is connected to an inverter, a message appears. Click OK to disconnect.) Start a new project. Open an existing project. Save the current project. Connect to an inverter. Disconnect from the inverter. Send the settings in the active project to the inverter (download the settings). 2 2 SW-XC-018 Revision C

25 Creating Projects Read the existing settings from the inverter (upload the settings). Open the help file. Creating Projects You can create a new RenConnectLite project to view and change the default parameter values for a specific inverter model/firmware combination. To create a project: 1. Double-click the RenConnectLite icon on the computer desktop. Or go to Start > All Programs > Schneider Electric > RenConnectLite > RenConnectLite. 2. Click Create Project.

Parameters that are related to safety or regulatory functions are read-only and appear grayed-out on the screen. To edit a parameter value: 1. Click the existing value, and then type a different acceptable value. Or, if the values are displayed within a drop-down list, select an option from the list. For information about acceptable values, see Range Limits on page 2 4. : If you cannot highlight the value, the parameter is read-only. 2. Click anywhere outside the value s box to enter the change. 3. Click Apply. Range Limits Many of the configurable parameters have a range limit. You can enter a value that is out of range but you cannot apply it to the configuration. The value is highlighted in red until you enter an acceptable value or cancel the change. For most parameters, the acceptable range is shown by the values in the Minimum Value and Maximum Value columns. An acceptable value is a value that lies between the minimum and maximum value, including the minimum value and the maximum value. When a changed parameter value is within the acceptable range, the box in the Value column turns yellow and a pencil icon appears in the Status column and on the tab. Figure 2-1 Updated parameters: within range 2 4 SW-XC-018 Revision C

27 Updating Parameters When a changed parameter value is outside the parameter s acceptable range, the box in the Value column turns red and a red exclamation point appears in the Status column, on the tab, and on the title bar of the pane. Applying Changes Figure 2-2 Updated parameters: out-of-range You cannot apply this unacceptable value and you cannot save the project until you change the value to one that is within the acceptable range. When you are satisfied with all the changes that you have made to parameter values, you can apply those changes. NOTICE UNINTENDED EQUIPMENT OPERATION Do not apply changes when RenConnectLite is connected to an inverter unless you understand fully how each change will affect inverter operation. Failure to follow these instructions can result in equipment damage.

Grid Settings The Grid Settings tab contains the parameters that determine how the inverter interacts with the grid. The grid qualification parameters determine when the inverter disconnects and reconnects to the grid. The option parameters determine how voltage and frequency are supported. Most grid settings are pre-determined by the utility region that is assigned to the inverter (see Grid Utility Region on page 3 3). In the rare case when an adjustment is required to any of these pre-determined values, you should carefully consider the impact on inverter and grid operations before making the change. Discuss the proposed change with the local Authority Having Jurisdiction (AHJ). NOTICE UNINTENDED EQUIPMENT OPERATION Do not send changed grid settings to the inverter unless you understand fully how each change will affect inverter and grid operation. Failure to follow these instructions can result in equipment damage. Grid Utility Region The Utility Region parameter identifies the country or region in which the utility operates and determines the settings for disconnection and reconnection to the grid as defined by the appropriate regulations. When the inverter leaves the factory, the Utility Region parameter is set to the value ordered by the customer. The available utility regions are: None CHINA MV-DG (A/I) *1 CHINA MV-DG (G/S) *1 P.O.12.3 *1 SW-XC-018 Revision C

The Reset button allows you to reset all the runtime counters to zero. The Log View area allows you to view and change the file path to the location of the runtime log file and set how much information is captured in the log file. The log mode can be set to capture only data from the event log (Error Logging), to capture data from both the data log and the event log (All Logging), or to disable logging (Deactivated). Address Table The Address Table tab allows you to view the address, name, and vendor of each inverter that RenConnectLite detects on the Modus. RenConnectLite is shipped with a default Modbus address of 248. This address enables RenConnectLite to work with any inverter, regardless of the address on the inverter.

59 4 Monitoring Inverter Activity Chapter 4, Monitoring Inverter Activity contains information on how to use the RenConnectLite software to monitor inverter activity and status and to save and restore an inverter configuration. Logging Event Logs Oscillography Monitoring Managing the Inverter Confirming Software and Firmware Versions SW-XC-018 Revision C

60 Monitoring Inverter Activity Introduction You can use RenConnectLite to review log files, counters, and oscillography as part of troubleshooting and maintenance activities. This section describes the parameters listed on the Logging, Event Logs, Oscillography, and Monitoring tabs in the Device Configuration window. It also describes the options available in the Device menu on the toolbar. Logging Working with Data Logs The Logging tab allows you to view, save, and clear the current data log, and to view settings for how often data is logged. If you require an adjustment to the logging rates, contact Schneider Electric. The data log contains up to 1,861 time-stamped records. Each record contains a predefined set of data, including kwh energy, grid AC voltage, inverter AC current, frequency, power, DC bus voltage, PV voltage, PV current, PV power, and ground current. You The following buttons enable you to manage data log files on RenConnectLite and on the inverter: Retrieve Data Log: Retrieves all the data log records from the inverter and displays them in RenConnectLite. Clear Logs in UI: Clears the display of retrieved data log records on the Logging tab in RenConnectLite. This command does not affect the data log records on the inverter. Save Data Log: Saves the data log records on the local computer in a commaseparated (CSV) format. Event Logs Events The Event Logs area enables users to view and manage information about system events, including signals that are detected. The event data is separated into two log files: events and service. The events log contains up to 8,192 time-stamped records. Events are stored in the events log whenever they occur, with a maximum rate of four simultaneous events within 1.5 ms. Each events log record contains a predefined set of data, including when the simultaneous events occurred, how long they lasted (in ms), and the nature of each event. 4 2 SW-XC-018 Revision C

61 Oscillography Service Working with Event Logs The service log is a subset of the events log when an event requires a service call, the event is added to the service log. The service log contains up to 910 time-stamped records. Each service log record contains a predefined set of data, including when the service event occurred, how long it lasted (in ms), and the nature of the event. The following buttons enable you to manage log files on RenConnectLite and on the inverter: Retrieve Logs: Retrieves all the event/service log records from the inverter and displays them in RenConnectLite. Clear Logs in UI: Clears the display of retrieved event/service log records on the Event Logs tab in RenConnectLite. This command does not affect the event/ service log records on the inverter. Save Logs: Saves the event/service log records on the local computer in a comma-separated (CSV) format. Oscillography The Oscillography tab provides data that is logged at a faster rate than the data log service. Users can view oscillography that the system records automatically during events (fast oscilloscope) or they can trigger an oscillograph themselves (slow oscilloscope). Fast oscillography is more accurate than slow oscillography since the device is capturing data continuously as events happen. Slow oscillography only occurs when triggered by a user and it does not capture data continuously; it only polls the device at regular intervals. Fast Oscilloscope (System Triggered) Fast oscillography is similar to a trigger in an oscilloscope. In RenConnectLite, the trigger is a service event. Oscillations are recorded 250 ms before and 250 ms after the last service event occurred. The resulting oscillograph contains 500 records taken at 1 ms intervals. Oscillations are recorded at 1 ms intervals Event Figure 4-1 Sampling timespan (fast oscilloscope) SW-XC-018 Revision C

62 Monitoring Inverter Activity It takes at least 30 seconds after the service event before oscillography data is available for retrieval using RenConnectLite. During this time, no new oscillography is logged. Each fast oscillography sample contains a predefined set of data, including grid AC voltage, inverter AC current, PV array voltage, PV array current, ground current, and DC bus voltage. To retrieve fast oscillography: 1. Confirm that a service event has occurred by checking the status statement above the oscillography pane. Device is OK means that no service events have occurred. Device is in fault state means that a service event has occurred. 2. Click the Retrieve button. The most recent fast oscillography sample appears in list view in the right pane of the Fast Oscilloscope tab. (500 entries in total) Figure 4-2 Sampling display (fast oscilloscope) 3. If you want to store the fast oscillography data on the local computer for offline viewing, click the Save button. 4. If you want to retrieve another fast oscillography sample, click the Clear UI button, and then click the Retrieve button. Slow Oscilloscope (User Triggered) Slow oscillography is a form of user-triggered data logging that adds the following features: The logging rate (1-30 sec intervals) is faster than data logging. The sample duration is finite (up to 1 hour of data). When the duration is exceeded, logging stops. Up to eight parameters can be selected for monitoring. Slow oscillography data is stored only in RenConnectLite, not on the inverter. The data takes longer to display than data from the fast oscillograph because it is recorded on demand. 4 4 SW-XC-018 Revision C

63 Oscillography Each slow oscillography sample contains a user-defined set of data. The user can select up to eight parameters to sample from a parameter list that includes active power, reactive power, apparent power, grid current, grid voltage, grid frequency, thermal loading, energy produced, temperature, PV voltage, PV current, PV power, and DC bus voltage. To start the slow oscilloscope: 1. Ensure that RenConnectLite is connected to the inverter see Setting Up Communication With the Inverter on page In the Device Configuration window, on the Oscillography tab, click Slow Oscilloscope. 3. Under Sample Duration, select the total time over which RenConnectLite should take readings. The options available for sample duration range from a minimum of 30 seconds to a maximum of one hour. 4. Under Sample Rate, select the frequency at which RenConnectLite should take readings. By default, RenConnectLite updates readings every half second. You can vary the sample rate from 0.5 second to 15 seconds. 5. Select the parameters to be sampled and traced by performing the following steps: a) Click the plus sign beneath the left pane. The Parameter Selection window appears. b) Select one or more parameters, up to a maximum of eight parameters, and then click OK. To select multiple parameters, hold down the Ctrl key. To remove a parameter from sampling, click the X below the pane. The selected parameters appear in the pane above the plus sign. The trace color that will be used to plot the oscillography appears beside each parameter. c) To change a trace color, click the color swatch beside the parameter, select a color from the color palette, and then click OK. 6. Click the play button above the oscillography pane to start monitoring. SW-XC-018 Revision C

64 Monitoring Inverter Activity Oscillography Toolbar The toolbar above the slow oscilloscope pane enables you to start and stop the sampling and to view and save the oscillograph. The following tools are available: Collapse the view so that the oscillograph fills the entire window. Expand the view so that the oscillograph is in the right pane and the configuration settings appear in the left pane. Start the sampling. Stop the sampling. Clear the oscillograph that you are viewing and start a new oscillograph. Save the oscillograph. Monitoring The Monitoring tab allows users to view live readings from the inverter about operational parameters, including PV and grid voltage, current, frequency, and power, energy produced, and heat sinks. You can set the rate at which RenConnectLite retrieves the readings (the default is one reading per second). You also select whether you want the results displayed graphically in gauge, linear, or digital format. To monitor inverter operations: 1. Ensure that RenConnectLite is connected to the inverter see Setting Up Communication With the Inverter on page In the Device Configuration window, on the Monitoring tab, under Type, select how you want to view the readings: displayed in a gauge format, as a digital value, or as a line graph. Figure 4-3 shows the available display formats. 4 6 SW-XC-018 Revision C

By default, RenConnectLite updates readings every second. You can vary the sample rate from 1 to 15 seconds. 4. Locate the values that you want to monitor in the list in the lower left pane, and then drag each value into the right pane. The graphic appears but does not show a live reading. 5. Click the play button to start monitoring. When you are finished viewing the continuous live readings, click the stop button to stop monitoring. Play Stop Managing the Inverter This section describes the options for sending commands to the inverter that are available in the Device menu on the toolbar. Clearing the Service Mode When a service event occurs (see Service on page 4 3), the inverter remains offline in Service mode until the cause of the fault is removed. If the service event is classified as low, the inverter returns to normal operation automatically. If the service event is classified as high, the inverter does not return to normal operation until the Service mode is cleared manually. Qualified users can clear the Service mode using the GKP or using RenConnectLite. : Qualified users are trained by Schneider Electric in servicing the Conext Core XC and Conext Core XC-NA inverters and have received a special service code.
