Glossary

AC
Abbreviation for „Alternating Current".
Anti-islanding protection
This is a unit for grid monitoring with assigned switching elements (anti-islanding protection) and is
an automatic isolation point for small power generation systems (to 30 kWp).
BDEW
Union of German Electrical Power Stations.
CE
With the CE identification code, the manufacturer confirms the conformity of the product with the
valid EC Guideline and compliance with the significant requirements stipulated therein.
DC
Abbreviation for „Direct Current".
EMC
The Electro-Magnetic Compatibility (EMC) concerns the technical and legal basics of the mutual
influencing of electrical devices through electromagnetic fields caused by them in electrical engi-
neering.
Galvanical isolation
No conductive connection between two component parts.
Initialization
Under initialization (cf. English to initialize) is understood the part of the loading process of a pro-
gram, in which the storage space required for the execution (e.g. variable, code, buffers ...) for the
program is reserved and is filled with initial values.
Local utility company
By local utility company is meant a company which generates electrical energy and distributes it
over the public grid.
MPP
The Maximum Power Point is the point of the current-voltage diagram of a PV cell at which the
largest power can be tapped off, i.e. the point at which the product of current and voltage has its
maximum value.
Nominal power
Nominal power is the maximum permissible continuous power output indicated by the manufacturer
for a device or a system. Usually the device is also optimized so that the efficiency is at its maximum
in case of operation with nominal power.
Nominal current
Nominal current is the absorbed current in case of electrical devices if the device is supplied with
the nominal voltage and yields its nominal power.
PE
In electric systems and cables a protective earth conductor is frequently employed. This is also
called grounding wire, protective grounding device, soil, grounding or PE (English „protective
earth").
