Sunny Boy 2500U

1 Introduction

The SMA Sunny Boy is a string inverter for grid tied operation. With this manual the
Sunny Boy can be installed and operated in a safe way. This installer's guide is used
as reference for the commissioning and as guideline on how to use all functions of
the inverter optimally and how you can extend your existing PV-plant.
Supplementary grid feeding includes the conversion of the DC-voltage from the PV-
panel to grid compatible AC-voltage with so-called "inverters" and the subsequent
connection to the electricity grid in the house distribution.
Here the electricity from the PV-modules provides all consumers with electric power
(household devices, lights etc.). In case that not enough power is produced the addi-
tionally necessary power is obtained from the grid. In case that there is a surplus of
power, this surplus is fed into the local grid and is therefore available for other con-
sumers. This way every single kilowatt-hour is utilized and the electricity company's
power systems are relieved. In the most simple case a PV-plant therefore consists of
two basic components: the PV-panel and the inverter.
