3 Initial Setup and Start
3.1 User
Interface
The user interface comprises:
•
Local display. Enables manual setup of the
inverter.
•
Web interface. Enables access to multiple
inverters via Ethernet.

3.1.1 Operation Modes
The inverter has 4 operation modes, indicated by LEDs.
For more information on the LEDs, refer to the
FLX Series
User Guide
.
Off grid
(LEDs off)
When no power has been delivered to the AC grid for
more than 10 minutes, the inverter disconnects from the
grid and shuts down. 'Off grid - standby' is the default
night mode. 'Off grid - sleep' is the night mode for lowest
energy consumption.
•
Off grid - standby mode
(LEDs off)
The inverter is disconnected from grid. User and
communication interfaces remain powered for
communication purposes.
•
Off grid - sleep mode
(LEDs off)
The inverter is disconnected from grid. User,
communication, and option interfaces are
powered down.
Connecting
(Green LED flashing)
The inverter starts up when the PV input voltage reaches
250 V. The inverter performs a series of internal self-tests,
including PV autodetection and measurement of the
resistance between the PV arrays and earth. Meanwhile, it
also monitors the grid parameters. When the grid
parameters have been within the specifications for the
required amount of time (depends on grid code), the
inverter starts to energise the grid.
On grid
(Green LED on)
The inverter is connected to the grid and energises the
grid. The inverter disconnects when:
•
it detects abnormal grid conditions (dependent
on grid code), or
•
an internal event occurs, or
•
insufficient PV power is available (no power is
supplied to the grid for 10 minutes).
The inverter then enters connecting mode or off grid
mode.
Fail Safe
(Red LED flashing)
If the inverter detects an error in its circuits during the self-
test (in connecting mode) or during operation, the inverter
goes into fail safe mode, disconnecting from grid. The
inverter will remain in fail safe mode until power has been
absent for a minimum of 10 minutes, or the inverter has
been shut down completely (AC+PV).
3.1.2 Security Level
3 predefined security levels filter user access to menus and
options.
Security levels:
•
Level [0]: General access. No password is required.
•
Level [1]: Installer or service technician. Password
access required.
•
Level [2]: Installer or service technician. Password
extended access required.
Throughout the manual, a [0], [1] or [2] inserted after the
menu item indicates the minimum security level required
for access.
When logged on to the web interface as Admin, access is
at security level [0].
Access to levels [1] and [2] requires a service logon,
comprising a user ID and a password.
