SMA Regelsysteme GmbH
2 Device Description
As the central component of a modular power supply system the Sunny Island will
not only convert the energy to supply various kinds of electrical consumers or to
charge its batteries but also allow to connect the SMA Sunny Boy
®
String Inverters for
supplementary grid feeding. Furthermore, small wind energy converters or generator
sets and even Combined Heat and Power units (CHPs) are also supported.
To fulfill its tasks the Sunny Island can work in different operating modes. A short
overview is given in Chapter 2.1.
An outstanding feature of the Sunny Island is its capability to take care of the con-
nected lead storage battery. Highly sophisticated charging algorithms assure a
maximum lifetime of the battery. A quick abstract of the battery management is given
in Chapter 2.2.
Although the first commissioning of stand alone systems using the Sunny Island can
be kept very simple, it is just as well possible to fine-tune the system by a vast num-
ber of parameters (see Chapter 16) giving the users complete satisfaction.
Moreover, using this system-compatible battery inverter lets the planner / installer
reduce planning, execution and system costs for PV island supply considerably.
