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 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
ES
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.

VISUAL INSPECTIoN, MAINTENANCE AND CLEANING
Visual Inspection
Check the inverter and cables for any signs of external damage. Contact your installer if you find any
damage. Do not carry out repairs yourself.
Maintenance and Cleaning
Have your installer check for proper inverter operation at regular intervals.
EN
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.
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.
