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.
