The main feature of a hybrid system is the use of two or more<br />
different electricity sources.<br />
Alongside solar energy, photovoltaic hybrid systems generally employ a diesel<br />
generator, a wind turbine or the public grid as a further electricity source.<br />
The inverters used in hybrid systems, which have integrated battery chargers,<br />
supply the connected AC loads according to demand from the battery bank<br />
of solar energy or the second electricity source. These devices also allow the<br />
batteries to be recharged from the extra energy source.<br />
Photovoltaic hybrid systems offer the advantage that the solar generator<br />
does not have to be significantly oversized for periods of low sunlight. This<br />
avoids substantial costs. When selecting its energy source, the system always<br />
gives priority to the energy provided by the module. In combination with a<br />
controllable second source, the energy supply remains reliable and available<br />
24 hours a day, all year round.<br />
