The principle behind photovoltaics is as clear as day:
When sunlight falls on the solar cell, a voltage is created
between its positively and negatively doped layers. If a
load is connected to this cell, then direct current begins
to flow. For this power to be used privately or put on the
public grid, then the direct current must first be converted
to alternating current. A solar inverter performs this DC
to AC conversion.
Solar inverters also perform other important tasks: They
monitor and control the entire system and store data
about the amount of current produced, which can be
displayed and analysed. Inverters also monitor the power
grid continuously to ensure that important safety criteria
are met.
Size matters for photovoltaic systems that are coupled
to a power grid: For small- and medium-sized systems,
the choice is string inverters. String inverters are linked
to multiple solar modules connected in series. For larger
systems, generator connection boxes consolidate multiple lines into a single central inverter. Central inverters
are used in large photovoltaic power stations that produce anywhere from hundreds of kilowatts to several
megawatts at peak production.

As for central inverters, AEG Power Solutions has developed the Protect PV central inverters line. Each individual inverter can provide 250, 560, 690 und 880 kVA of
power, and the number of inverters can be scaled up to
meet requirements. System owners typically use fallow
open spaces for the module trusses and store additional
equipment in containers or housings.
For a turn-key solution, AEG Power Solutions also offers
the TKS-C series, consisting of two central inverters, a
high-performance medium-voltage system and an onsite monitoring and control system.
Photovoltaic power stations with higher power outputs
require more modules in order to use the inverters to
full capacity. Approximately 4500 to 5000 solar modules
are needed to produces one megawatt of power using
a TKS-C 1000. These modules occupy a surface area of
around 9,850 square metres which is approximately one
and a half soccer fields.
