PV module
Part of a PV generator; converts PV energy into electrical energy.
RJ45
Abbreviation for standardized eight-pole electrical connector connection. RJ stands for
Registered Jack (standardized socket).
RS485 (EIA485)
Differential voltage interface on which the genuine signal is transmitted on one core and
the negated (or negative) signal on the other core.
Separate grid system
Energy supply equipment which is completely independent of an interconnected grid.
Solar inverter
is an electrical device which converts DC direct voltage into AC voltage and/or direct
current into alternating current.
String
Designates a group of electrical PV modules switched in series.
String solar inverter (solar inverter concept)
The PV generator is divided up into individual strings which feed into the grid over
their own string solar inverters in each case. In this way, the installation is considerably
facilitated and the gain decrease, which can arise from the installation or from different
shading conditions of the PV modules, is considerably reduced.
TAB (2000)
The TAB 2000 are the technical regulations governing connection to the low-voltage
grid operated by distribution system operators in Germany. These Technischen
Anschlussbestimmungen or TAB for short have been in force since the year 2000. They
define the requirements imposed by DSOs on the electrical systems operated by the
end customers of utility companies.
