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

dene the requirements imposed by DSOs on the electrical systems operated by the

end customers of utility companies.
