Symbols on the Inverter

Operation display.

Ground fault or varistor defective. Please inform your installer.

An error has occurred. Please inform your installer immediately.

Tap to switch on the display light and switch to the next message.

Symbols on the Type Label

Beware of dangerous electrical voltage.
The inverter operates at high voltages. All electrical work

on the inverter may be carried out by quali󹻭ed personnel only.

erfolgen.

Beware of hot surface.
The inverter can become hot during operation. Avoid contact during operation.

Observe enclosed documentation.

The inverter must not be disposed of with the household waste.
Further disposal information can be found in the enclosed installation guide.

CE mark. The inverter complies with the requirements of the applicable EC
guidelines.

RAL quality mark for solar products. The inverter complies with the requirements of
the German Institute for Quality Assurance and Labeling.

Direct Current (DC)

Alternating current (AC)

The inverter is protected against penetration by dust particles and water jets from
any angle.

The inverter has a transformer.

AC

Abbreviation for “Alternating Current”.

DC

Abbreviation for "direct current".

Derating

A controlled reduction in performance, usually dependent on component temperatures.

Electronic Solar Switch (ESS)

The Electronic Solar Switch is part of the inverter's DC switch-disconnector. The
Electronic Solar Switch must be securely inserted into the bottom of the inverter and may

only be removed by quali󹻭ed personnel.

MPP (Maximum Power Point)

Operational point of the inverter, dependent on current / voltage of the PV generator. The actual
position of the MPP changes constantly, depending on the level of solar irradiation and the cell
temperature.

PV

Abbreviation for photovoltaics.

Varistor

The varistors protect the electronics in the inverter from atmospherically coupled energy peaks, such as
those that can occur in the event of nearby lightning strikes.

Installer contact

Visual inspection

Check the inverters and the cables for visible external damage. Contact your installer if you 󹻭nd any

defects. Do not perform any repair work yourself.

Maintenance and Cleaning

Have your installer check for proper inverter operation at regular intervals.

VISUAL INSPECTION, MAINTENANCE AND CLEANING

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 quali󹻭ed personnel only:

• Electrical installation

• Repairs

• Modi󹻭cation

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 󹢵ashes 4 times.

Destruction of the inverter.

• Inform your installer immediately if the yellow LED starts
󹻮ashing 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.

Tap again

The display switches to the next noti󹻭cation.

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

Power produced so far
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

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

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.
