DANGEr!
Electric shock caused by high voltage in the inverter.
Even when no external voltage is present, there can still be high voltages in the device.
The following work may be carried out by qualified personnel only:
• Electrical installation
• Repairs
• Modification
CAUTION!
risk of injury from touching the enclosure during operation.
Burns to the body.
• Only touch lid and display during operation.
NOTICE!
Overvoltage in the inverter if yellow LED flashes 4 times.
Destruction of the inverter.
• Inform your installer immediately if the yellow LED starts
flashing and the following display message appears.
Operation The display shows current values of your system. The displayed values
are updated every 5 seconds. The display is operated by tapping on it.
Tap once: The backlight is switched on. After 2 minutes, the illumination
switches off automatically.
Tapping once more:The display switches to the next notification.
Tapping twice: The display successively shows inverter type, firmware
version of the internal processors and configured country standard.
Display messages
Operation Upon error-free connection of the inverter to the grid, the following
messages are shown in turn after approximately 1 minute. Each
message appears for 5 seconds, then the cycle starts again.
Power produced on the current day
Operating state
Current feed-in power
PV generator voltage
Total amount of feeding-in energy
Total number of grid-feeding operational hours
Disturbance In the event of a disturbance, the inverter will display the status
"Disturbance" and an error message. Please inform your installer.
The following messages will be issued:
Power produced on the current day
Operating state "Disturbance"
Operating state
Error message
Measured value at time of disturbance
Current measured value (only displayed if a measured value is
responsible for the disturbance)
DC overvoltage
The DC input voltage connected to the inverter is too high.
Please inform your installer immediately.

Waiting, Grid
Monitoring
The inverter monitors the grid and waits for the DC
voltage to reach a certain level so that it can start
feeding the grid.
Stop Interruption of operation.
Derating Overtemperature in the inverter.
Red LED is
glowing
Warning A grounding error has occurred, or one of the
thermally monitored varistors on the DC input side is
defective. Please inform your installer.
Yellow LED

continuously
Disturbance The inverter is operating in "Operation constantly
disabled" mode. This can have several causes.
Please inform your installer.
Yellow LED

Disturbance The inverter displays a disturbance. This can have
several causes. Please inform your installer.
If your inverter is equipped with a communication component, then numerous measuring channels
and messages can be transmitted for diagnosis.

Your inverter can be in various operating modes. These are displayed as status messages, which can
vary according to the method of communication.
Message Description
Derating Overtemperature in the inverter. The inverter will reduce its output to prevent
overheating. To avoid unnecessary output losses, the design of the PV plant
should be checked. Please inform your installer.
Disturbance Disturbance. This message appears for reasons of safety and prevents the
inverter from connecting to the grid. Please inform your installer.
Error An error has been detected. Please inform your installer.
grid mon. Grid monitoring
This message appears during the startup phase, before the inverter connects to
the grid; it usually appears in the morning and evening when there is little solar
irradiation an after an error has occurred.
MPP The inverter is operating in MPP mode. MPP is the standard display message
when operating under normal irradiation conditions.
Off Grid The inverter is in "Island" mode. This mode has been specially conceived for
operation in an off-grid power system with a Sunny Island as grid controller.
offset Offset adjustment of measurement electronics.
Riso Measurement of the insulation resistance of the PV system.
Stop Interruption of operation.
V-Const Constant voltage operation.
