Photovoltaic hybrid systems offer the advantage that
the solar generator does not have to be significant-
ly oversized for periods of low sunlight. This avoids
substantial costs. When selecting its energy source,
the system always gives priority to the energy provi-
ded by the module. In combination with a controlla-
ble second source, the energy supply remains reliab-
le and available 24 hours a day, all year round.
The main feature of a hybrid system is the
use of two or more different electricity sour-
ces.
Alongside solar energy, photovoltaic hybrid systems
generally employ a diesel generator, a wind turbine
or the public grid as a further electricity source. The
inverters used in hybrid systems, which have integra-
ted battery chargers, supply the connected AC loads
according to demand from the battery bank of solar
energy or the second electricity source. These devices
also allow the batteries to be recharged from the
extra energy source.
Hybrid systems
Important features for single-phase and
three-phase hybrid systems
Combination of different power sources such
as PV, wind, diesel generators
400 V AC three-phase and 230 V AC single-
phase available 24 hours a day
12 V / 24 V or 48 V overall DC bus
Automatic energy management based on the
state of charge calculation of the battery, in-
cluding automatic start of controllable power
sources like e. g. diesel generators
Optimised battery charging algorithm
Data logger function with automatic alarm
and remote monitoring (GSM)
