VISUAL INSPECTIoN, MAINTENANCE AND CLEANING
Visual Inspection
Check the inverters and the cables for visible external damage. Contact your installer if you find any
defects. Do not perform any repair work yourself.
Maintenance and Cleaning
Ask your installer to check for proper inverter operation at regular intervals.

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 qualified personnel only.
Beware of hot surface.
The inverter can become hot during operation. Avoid contact during operation.
Observe the 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.

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 disconnection unit. The
Electronic Solar Switch must be securely inserted into the bottom of the inverter and may
only be removed by qualified personnel.
Grid impedance
The grid impedance is a characteristic grid specification, which is determined both by the grid
infrastructure, and by the number of power suppliers and power consumers. If the supply for the
grid section should drop due to a grid shutdown of 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 off-grid system, 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)
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.
SMA Power Balancer
The SMA Power Balancer prevents the formation of an unbalanced load > 5kVA (in Italy > 6kVA)
during three-phase grid feed-in. To this effect, 3 Sunny Mini Centrals are each connected via a control
line to a 3-phase feeding unit.
Unbalanced load
The unbalanced load is the difference between the power fed into the grid at the individual line
conductors. In Germany, this must not exceed 5 kVA. In Italy, the unbalanced load 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.
