2 The Sunny Island 5048
2.1 Properties
The Sunny Island 5048 is a bidirectional
inverter (battery inverter and charger) for
stand-alone systems. The Sunny Island 5048
supplies loads on the stand-alone grid side
and charges battery banks with power that
is provided by feeding electricity into the
grid on the AC side.
The comfortable support of AC and DC
coupling, and the extendibility of the systems
formed by the Sunny Island 5048 guarantee
maximum flexibility. Thanks to innovative
technology, the Sunny Island 5048 also
achieves a maximum efficiency of more than
95 %. Optimized for operation under partial
load, it simultaneously impresses with its low
consumption when idle or in standby mode. Due to the high overload capabilities and
the integrated output management, there is no need to oversize the Sunny Island.
The parallel operation of up to four devices on a single phase of a battery or three
devices on a three-phase system enables the Sunny Island 5048 to setup stand-alone
power supplies with outputs ranging from 3 kW to 26 kW (in multicluster operation up
to 78 kW).
Thanks to its sophisticated generator management, it can control connected diesel
generators in a particularly sparing and fuel-saving manner. It can also be integrated
into the public grid. The Sunny Island 5048 can also automatically deactivate loads if
the battery does not have sufficient electrical energy available.
The stand-alone grid's critical component, the battery, is monitored diligently and
utilized optimally. The intelligent battery management precisely records the battery's
charge level. This enables improved utilization of battery capacity, which also means
that smaller and thus more cost-effective batteries can be used without affecting
performance.
In order to prevent premature aging caused by incorrect charging and frequent deep
discharge, the Sunny Island 5048 has an intelligent charge control and reliable deep
discharge protection. When these functions are properly used, the battery service life
can be greatly extended in comparison with simpler devices.
Despite the complex function of this battery inverter, the Sunny Island 5048 is easy to
configure. All the settings required for operation can be quickly and easily programmed
in ten steps using the "Quick Configuration Guide". By employing the concept of central
operation referred to as "Single Point of Operation", the system/cluster parameters are
only set on the master device, and all other devices automatically adopt the

configuration. The easy-to-understand menu navigation allows quick access to all
important data, even while the system is running. An MMC/SD card provides
uncomplicated system control, and thus makes any service work easier.
The Sunny Island 5048 monitors the set voltage and frequency limits on the grid and
the generator. If these limits are not within the permissible range, it disconnects the
external source without interruption and goes into stand-alone grid operation. The
Sunny Island 5048 also has an integrated anti-islanding process that prevents a stand-
alone grid from accidentally being created on the public grid. If this process is
triggered, the system also completely switches into stand-alone mode without
interruption.
The Sunny Island 5048 can be integrated into different system constellations. The
graphic on the next page displays which components can be integrated into a Sunny
Island system.
The graphics on the page after next display the different wiring options (1-phase, 1-
phase parallel and 3-phase).
The Sunny Island 5048 does not meet the VDE 0126-1-1 directive required
in Germany and, for legal reasons, it must therefore be MSD-certified (e.g.
by UfE GmbH) when operated while connected to the public grid.
