Modular Extension of the Battery

PRIMARY
BATTERY CABINET
Figure 12: Modular design of the battery
The storage system can be extended both in terms of the energy content and the charging and discharging capacity.
Take the specifications relating to the possible system configurations into account (see Technical Information "System
Configuration - SMA Commercial Storage Solution").
The energy content can be extended by operating up to four battery cabinets via a common DC distributor and
connecting them to the inverter. The battery management system of one battery cabinet controls and monitors the
entire battery-storage system and thus acts as the primary battery cabinet. The battery management systems of the
other battery cabinets act as secondary battery cabinets and follow the instructions of the primary battery cabinet.
Additional battery cabinets may be installed in this battery cabinet a maximum of six months after the battery cabinet is
first commissioned.
The storage system can be extended in terms of the charging and discharging capacity by connecting a number of
Sunny Tripower Storage X systems to an SMA Data Manager M via a local network. Observe the system limits of the
Sunny Tripower Storage X.
