About RenConnectLite
RenConnectLite is a PC-based software program that enables owners of
Schneider Electric Conext Core XC Series Grid-tie Photovoltaic Inverters to
configure and monitor their inverters. RenConnectLite offers features for
management of inverter configuration through a user-friendly interface. Some of
the benefits include:
Reduced User Error: RenConnectLite provides a simple user interface that
makes it easy to see where you have made changes to parameter values and
alerts you to errors.
Easy Comparison of Configurations: RenConnectLite allows you to export
project files in text or HTML format so that you can compare two or more
configurations and identify differences.
You can use RenConnectLite to monitor inverters by retrieving log files, viewing
counter values, retrieving oscillography, and viewing live readings. The user can
also enable or disable the inverter remotely and save and restore the inverter
configuration when needed.
For details about using RenConnectLite to maintain inverters, see Chapter 4,
“Monitoring Inverter Activity”.

Getting Started
Starting RenConnectLite
After you install the RenConnectLite software successfully, double-click the
RenConnectLite icon on the computer desktop to start the software.
If the icon is not on the desktop, go to the Programs directory on your computer
to locate it. For example, on a Windows 7 system, go to Start > All Programs >
Schneider Electric > RenConnectLite > RenConnectLite.
The RenConnectLite Home screen appears.
Create Project
A project is a file of inverter configuration settings with the extension *.renl. When
a user selects an inverter model and firmware combination, RenConnectLite
creates a project file containing default settings. You can edit the settings and
save them as a new project file. For details about creating new project files, see
“Creating Projects” on page 2–3.
Open Project
If you know the location of a saved project file, you can use the Open project
button to locate and open it in RenConnectLite. The file must have the *.renl
extension and must have been created with the same version of RenConnectLite
or an earlier version.
You can find the project files in one of the following locations:
•
Windows XP:
C:\Documents and Settings\All Users\Application Data\Schneider
Electric\RenConnectLite\Projects
•
Windows 7:
C:\ProgramData\Schneider Electric\RenConnectLite\Projects
If the project that you attempt to open is not compatible with the RenConnectLite
version that you are using, a message appears and the project file does not
open. Ensure that you are using the latest version of RenConnectLite before
opening an existing project.
You can open an existing project even if the RenConnectLite software is not
running. Locate the *.renl file on your computer and double-click to open it.
RenConnectLite starts and the project opens.

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

Updating Parameters
The RenConnectLite interface simplifies updating parameter values to suit a
particular inverter configuration. The parameters are listed in a table with
descriptions, units, default values, and the range of acceptable values. You
cannot change every parameter. 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.

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

Power Tracking
The Power Tracking tab contains inverter-PV parameters, including the
thresholds at which the inverter connects to the PV array and goes online
(normally at daybreak), disconnects from the PV array and goes offline (normally
at nightfall), and performs power point tracking.
The tables in this section list the default values for power tracking. Some settings
are read-only (that is, they are grayed-out in RenConnectLite) and can only be
changed by contacting Schneider Electric. These settings are indicated by gray
shading in the tables in this section.
You can adjust any settings that are not grayed out in RenConnectLite. Before
making any changes to settings, refer to the Application Note on Power Tracking
for Conext XC Series Inverters (document number 976-0296) for important

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
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
Working with Data Logs
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
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.
Events
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
This manual is for use by qualified technicians only
Oscillography
Service
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.
Working with Event Logs
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

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)

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.

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.

When RenConnectLite is connected to an inverter, you can update the inverter’s
clock to match the laptop computer clock. This is useful for ensuring that logging
starts at the exact time of day or night that you set (see “Working with Data Logs”
on page 4–2).
To synchronize time:
1. Connect the computer to the inverter as described in “Setting Up
Communication With the Inverter” on page 1–5.
2. From the Device menu, select Synchronize device time to PC. (This option is
grayed out when RenConnectLite is not connected to an inverter.)
Device Services
When RenConnectLite is connected to an inverter, it retrieves information from
the inverter for display in the Device Services window, as shown in Figure 4-4.
The Device Services option is unavailable when RenConnectLite is not
connected to an inverter.

Device Status
Device status information is retrieved from counters and helps service personnel
to assess the life cycle of key components of the inverter. The counters that
RenConnectLite reads include the number of operating hours, kWh energy
produced, and how often the AC and DC switches have been opened.
Device State
Device state information is retrieved from the log files and helps service
personnel to assess the current operational condition of the inverter. The states
that RenConnectLite reads include operational state, system state, event state,
and alarm state.
