Appendix
Glossary
A number of specialist terms are used in this manual which are briefly explained
as follows:
AC Alternating Current
Arc A dangerous electrical current which flows
through the air and which occurs when the
positive and negative poles of a high voltage
come too close together.
Autonomous system A system that is not connected to the public
electricity grid and that stores energy, that is
not immediately required, in batteries.
CE A certification mark that shows that the prod-
uct is compliant with European requirements.
Connector Plug or socket
Cooling profile A profile on the rear side that is used to dis-
sipate heat and thereby serves to cool the
inverter.
DC Direct Current
Derating Reduction in the output emitted by the
inverter with the aim of lowering the tem-
perature inside the inverter or to stop the
temperature from rising any higher.
Efficiency In this case: the percentage of DC power that
is converted into AC power.
EMC Electromagnetic compatibility. The inverter
must not send out any interfering electro-
magnetic signals and must also not be sus-
ceptible to any.
European efficiency A measure of the average efficiency of an
inverter over the course of a year
Grid-connected system A PV system that is connected to the public
grid
IEC 60364-7-712 Paragraph relating to PV in the installation
standard for buildings
Input current The current that the solar modules produce
Input voltage The voltage of the solar modules
Inverter The inverter converts the direct current from
the solar modules into alternating current
suitable for the public electricity grid.
