PV module
Part of a PV generator; converts PV energy into electrical energy.
RS485 (EIA485)
Differential voltage interface on which the genuine signal is transmitted on one core and the ne-
gated (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 de-
crease, which can arise from the installation or from different shading conditions of the PV modules,
is considerably reduced.
