2 The Sunny Island 3324/4248
2.1 General Description
The Sunny Island 3324/4248 is a bidirectional battery power converter (battery
inverter and charger), ideally suited for use in stand-alone grid operation. This
inverter allows you to charge lead acid batteries, using power sources provided on
the AC side (e.g. generator, public grid, Sunny Boy). The Sunny Island 3324/4248
creates a 230 V AC stand-alone grid using the energy stored in the batteries,
allowing stable operation of connected loads and power generation devices (e.g. PV
inverters).
Energy sources can also be connected on the DC side, as long as the specified limits
are not exceeded (see section 12 "Technical Data" (page 61)).
The Sunny Island 3324/4248 is able to control a starter contact for a generator and
automatically connect or disconnect it to an AC-grid (see section 5 "Generator
Settings" (page 29)).
The Sunny Island 3324/4248 can also switch off particular loads if the batteries do
not have sufficient electrical energy available.
The Sunny Island 3324/4248 can be used in different system configurations.
Detailed information on the different stand-alone systems can be found in the
installation manual.
