The extremely low specific price makes
the Sunny Boy 2500 SMA's best bargain.
Its nominal power of 2200 W can be fed to
the grid over the whole input voltage range of 250 to
600 V due to a maximum current of 11 A . The Sunny Boy
2500's maximum efficiency of 94 % is even higher than
that of the smaller transformer-based devices of the
Sunny Boy Family.
The variable DC input range and the possibility to
connect up to three strings with the reliable
Multi-Contact connectors make any module configuration
possible. These features enable the operator to freely
design and implement personal needs for the solar
system. However, the optimal
configuration is a solar generator with an output of
2750 to 3450 W.
Basically the Sunny Boy 2500 implements operating
experience with the smaller Sunny Boy 700, 850 and
1100E inverters. The development of the Sunny Boy 2500
was based on these fully operational devices. The
sequential control system has remained the same.
