User Manual

Symbols on the Inverter

Operation display.

An error has occurred. Inform your installer immediately.

Bluetooth® Wireless Technology. Bluetooth communication active.*

Symbols on the Type Label

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

carried out by electrically qualied persons 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 together with the household waste.
Further disposal information can be found in the enclosed installation manual.

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.

Device class label. The inverter is equipped with a wireless component that complies
with the harmonized standards.

Certied safety. The inverter complies with the requirements of the Europe

Equipment and Product Safety Act.
Australian mark of conformity

Korean mark of conformity

Direct current (DC)
Alternating current (AC)

The inverter is protected against dust intrusion and water jets from any angle.

The inverter has a transformer.

of these marks by SMA Solar Technology AG is under license.

AC

Abbreviationfor "alternating current".

Bluetooth

Bluetooth is a radio technology that allows the inverterand other communication devices to

communicate with each other. Bluetooth communication does not require visual contact between the
devices.

DC

Abbreviation for "direct current".

Electronic Solar Switch (ESS)

The Electronic Solar Switch is part of the inverter DC disconnection unit. The Electronic Solar Switch
must be securely inserted into the bottom of the inverter and may only be removed by an electrically

qualied person.

Energy

Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours). The energy
is the power calculated over time. If, for example, your inverter operates at a constant output of
3 000 W for half an hour and then at a constant output of 2 000 W for another half hour, it has fed
2 500 Wh of energy into the power distribution grid within that hour.

Power

Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an instantaneous value.
It displays the power your inverter is currently feeding into the power distribution grid.

PV

Abbreviation for photovoltaics.

Visual inspection

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

nd any damage. Do not perform any repair work yourself.

Maintenance and Cleaning

If the display eld or the LEDs are dirty and you nd it dicult to read the operating data and

operating states of the inverter, clean the display and the LEDs with a damp cloth. Do not use any
corrosive substances (e.g. solvents, abrasives) for cleaning. Ask your installer to check for correct
inverter operation at regular intervals.

DANGER!

Electric shock caused by high voltage in the inverter.

Do not open the inverter!

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

• Electrical installation, repair and retrotting may only be carried out by a trained
electrically qualied person:

• Physically or mentally challenged persons may only perform activities on the inverter

following proper instruction and under supervision.

• Children must not play with the inverter. Children must not have access to an inverter
in operation.

CAUTION!

Risk of burns through contact with the enclosure during operation.

• During operation, only touch the lid and display.

Yield loss due to poor heat dissipation.

• Do not place any objects on the enclosure.

The inverter energy and/or power is shown as a diagram on the
display. The daily graph is displayed by default. The right-hand

ashing bar of the diagram represents the current hour. If the

inverter does not feed any power to the power distribution grid
over a longer period of time (e.g. in darkness or if the PV modules
are covered with snow), a gap is inserted into the chart. The

column for the current hour is updated automatically every ve

seconds.
After four seconds, the bar goes off for one second and then
displays the current value.

Green LED is on: Operation

Green LED is ashing: Waiting for sucient irradiation

Red LED is on: Disturbance: contact installer

Blue LED is on: Bluetooth communication is active. The inverter can communicate with other

SMA Bluetooth devices with identical NetID.

Blue LED is ashing: The inverter was identied via Sunny Explorer by setting the "Find device"

parameter.

The power and energy of the inverter are displayed in three elds: Power, Day and Total. The
display is updated every ve seconds.

Power

The power that the inverter is currently feeding into the power
distribution grid.

Day

The energy fed into the power distribution grid on this particular day.
This equals the energy generated between the inverter's start-up in the
morning to the current time.

Total

The total energy that the inverter has fed into the power distribution
grid during its entire operating time.

MEASUREMENT ACCURACY

The display values may deviate from the actual values and must not be used as a basis for invoicing.
The inverter's measured values are required for the operational control and to control the current to
be fed into the power distribution grid. The inverter does not have a calibrated meter.

Text line for displaying an event

Graphical display of the inverter energy/power

The display updates the values of your PV plant every 5 seconds.

You can operate the display by tapping it:

• Tapping the enclosure lid once: The background illumination is
activated, switch between the power range of the past 16 feed-in
hours and the energy yields of the past 16 days, switch to the
next text line

• Double tapping (valid as of rmware version 2.30): the inverter
shows, in succession, the rmware version, the serial number

and designation of the inverter, the Bluetooth NetID, and the

specied country standard and display language.
