Symbols on the Inverter

Operation display.

Ground fault; varistor defective or string fuse defective.

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.

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 is transformerless.

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 disconnection unit. 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
MPP changes constantly, depending on, for example, the level of solar radiation and the cell
temperature.

PV

Abbreviation for photovoltaics.

Reactive Power Control

Inverters with Reactive Power Control are inverters capable of utilizing reactive power. By setting

a default value for the displacement factor (cos ϕ) they can feed reactive power to the grid.

SMA Power Balancer

The SMA Power Balancer is a serial feature of the Sunny Mini Central. The SMA Power
Balancer prevents the formation of an unbalanced load > 5kVA during three-phase grid feeding
(in Italy > 6kVA). To this effect, 3 Sunny Mini Centrals are each connected via a control line to a
3-phase feeding unit.

Unbalanced load

The difference between the power fed into the grid at the individual phase conductors. In
Germany, this must not exceed 5 kVA. In Italy the power is restricted to 6 kVA.

Varistor

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

Visual Inspection

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

damage. Do not carry out repairs yourself.

Maintenance and Cleaning

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

Message Description

Balanced The Sunny Mini Central has disconnected from the grid, or is limiting its output

to 5 kVA over a 10-minute average. The Sunny Mini Central is part of a three­phase system equipped with two further Sunny Mini Centrals and the SMA Power
Balancer to avoid unbalanced load.

Derating Overtemperature in the inverter. The inverter reduces its output to prevent it from

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 display appears during the start phase, before the inverter is connected to the
grid, predominantly in the mornings and evenings when the solar radiation is low
and after an error.

MPP The inverter is operating in MPP mode. MPP is the standard display when

operating with normal solar radiation.

MPP-Search The inverter is calculating the MPP (Maximum Power Point)

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 Operation interrupted.

V-Const Constant voltage operation.

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

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.
