EXPLANATION OF SYMBOLS

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 Plate

Beware of dangerous electrical voltage.
The inverter operates at high voltages. Any work on the inverter must be carried out

by quali󹻭ed personnel only.

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.

VISUAL INSPECTION, MAINTENANCE AND CLEANING

Visual inspection

Check the inverter and cables for any signs of external damage. Contact your installer if you 󹻭nd any

defects. Do not carry out any repairs on your own.

Maintenance and Cleaning

Ask your installer to check for proper inverter operation at regularly.

GLOSSARY

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 isolator. The Electronic Solar Switch must be

securely inserted into the bottom of the inverter and may only be removed by quali󹻭ed personnel.

Grid impedance

Grid impedance is a characteristic parameter of the power network, which is determined by both its
infrastructure and the number of feed units and loads. If the supply for the grid section should drop
due to a grid shutdown by the preceding energy suppliers (medium-voltage transformers), the grid
impedance will change abruptly. In order to detect this and to prevent the formation of an unwanted
stand-alone grid, SMA Grid Guard monitors the grid impedance and disconnects the inverter from the
grid in the event of a sudden impedance variation.

MPP (Maximum Power Point)

ES

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 when lightning strikes nearby.

SAFETY INSTRUCTIONS PRODUCT OVERVIEW

DANGER!

Electric shock caused by high voltage in the inverter.

Even when no external voltage is applied, high voltages can be present in the inverter.

The following work must only be carried out by quali󹻭ed personnel:

• 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 should
start 󹻮ashing and the following display message appears.

Operation

Display messages

In operation

Disturbance

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 background illumination is switched on. After 2 minutes, the
illumination switches off automatically.

Tap again

The display switches to the next noti󹻭cation.

Upon error-free connection of the inverter to the grid, the following
messages are shown in turn after approximately one minute. Each

message appears for 󹻭ve seconds, then the cycle starts again.

STATUS MESSAGESMEASURING CHANNELS

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 safety reasons 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 a stand-alone grid with a Sunny Island as grid controller.

Offset Offset adjustment of measurement electronics.

Riso Measurement of the insulation resistance of the PV system.

Stop Operation interrupted.

V-Const Constant voltage operation.

Waiting The conditions for connecting are not (yet) ful󹻭lled.
