SMA Solar Technology AG The Sunny Backup System S
2 The Sunny Backup System S
2.1 Properties
The Sunny Backup System S consists of one Sunny Backup 2200 in combination with one Automatic
Switch Box S (AS-Box-S.1), one external Sunny Remote Control 1 (SRC-1) display and one external
BatFuse A.01 DC fuse. This system is specially designed for backup applications and enables, in
compliance with all standard requirements, continued operation of a grid-connected PV system in the
event of grid failure. Thus, this system does not replace the conventional Sunny Boy (PV inverter), but
is installed additionally. In the event of grid failure, the Sunny Backup System S first ensures safe
disconnection of the loads and the PV system from the public grid, and subsequently forms a stable
stand-alone grid, into which the Sunny Boy can then feed solar energy. The maximum period of
interruption for the loads is approximately 50 ms, which for most loads is equivalent to uninterrupted
operation.

The Sunny Backup System S is suitable for use in conjunction with the Sunny Boy PV inverters from
SMA Solar Technology AG. The Sunny Backup System S can be integrated into new PV system
installations, and can also be retrofitted onto existing PV systems.
Along with the Sunny Backup 2200 and the automatic switching device AS-Box-S.1, a battery is
necessary as a short-term storage device, for reliable operation. During grid failure, the battery has
the task of correcting the imbalance between generation and consumption. Whenever less energy is
being generated than consumed (e.g. at night), the battery is discharged. Whenever more energy is
being generated than consumed (e.g. during the day), the battery is charged.
Technical Description SBU2200-TEN083320 11
The Sunny Backup System S SMA Solar Technology AG
The intelligent battery management built into the Sunny Backup 2200 protects the battery from
overcharging and deep discharge. This ensures that the battery service life stipulated by the battery
manufacturer can be achieved.
As an external DC fuse, the BatFuse A.01 protects the battery connections of the Sunny Backup 2200.
Additionally, the BatFuse A.01 enables the DC-side disconnection of the Sunny Backup 2200.
The Sunny Backup 2200 performs the entire controlling and regulation of the system. If the system is
in grid-parallel operation, the Sunny Backup 2200 ensures standard-compliant grid monitoring and
battery-preserving charging. The Sunny Backup 2200 is extremely quick to detect any failure of the
public grid and disconnects the system from the grid. After approx. 50 ms, the loads will be already
supplied with electricity again, from the battery. After a matter of seconds, the PV system switches to
this stand-alone grid, and either powers the loads, or is used for recharging the batteries. The
efficiency during charging, regardless of whether from the grid, or from the PV system, and during
discharging, is up to 93 %. Due to the 's very high overload capability of up to 3.8 kW for 5 minutes,
and the integrated smooth startup of the Sunny Backup 2200, critical loads with very high start
currents can also be started safely. Thus, over-dimensioning of the Sunny Backup 2200 is not
necessary.
Requirement according to VDE 0126-1-1 and guidelines of other countries
The Sunny Backup System S meets all requirements of the VDE 0126-1-1 guidelines that
are required in Germany for feeding PV electricity into the grid as well as guidelines of
other countries. The switching devices for PV feeding are implemented redundantly, and
are monitored. The safety of this system has been inspected and certified by the German
Professional Association for Precision Engineering and Electrotechnology.
Information
The Sunny Backup System S is only intended for use in TN systems!
Despite the complex functions of the Sunny Backup system, it can be installed and configured with
ease. All special material required for installation is included in th e de liv ery . Additi ona l su b-d ist rib uti on
units are generally not necessary. The safety and fuse protection concept on the consumer side, and
that of the PV system, are generally not impaired by the Sunny Backup 2200, and do not need to be
adapted.
All the settings required for operation can be quickly and easily programmed in six steps using the
"Quick Configuration Guide" of the Sunny Backup 2200. 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.
