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 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

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.

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 qualified 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)

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.

Visual inspection

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