In an article published in the VDI-Nachrichten on 23 May report of the Karlsruhe Institute of Technology (KIT) safety deficiencies in Li-Ion based were published PV battery storage systems that can at worst lead to fires and explosions. SMA Solar Technology AG (SMA) supports the concerns of the KIT to provide more security in connection with Li-ion storage, but regrets that associated with the undifferentiated type of issue by the KIT uncertainty among consumers and customers. At the same time underlines SMA, that in the development of their own storage systems, the security from the beginning the top priority.
“SMA has over twenty years of experience in dealing with battery storage systems and works intensively for five years with the lithium-ion technology. In addition, the two storage systems available on the market SMA Sunny Boy and Sunny Smart Energy Iceland have sophisticated security concepts, so that the effects described by the KIT are almost completely excluded. That’s why we have the Sunny Boy Smart Energy fully tested prior to launch in April and in the development of early VDE with integrated, which has the security of the system finally certified, “says SMA storage expert Martin Rothert.
The for the battery pack of the Sunny Boy Smart Energy cells used comply with automotive quality standards and are used in commercially available hybrid and electric vehicles by the thousands. The battery pack is certified according to UN 38.3 (Transportation Safety) and meets all other requirements contained therein, for example in relation to internal short circuit (shock and vibration test), external short circuit and overcharge. Additionally, the Sunny Boy Smart Energy has a multi-level, redundant safety concept for monitoring and electrical separation of the battery pack to prevent an external short circuit and overload safe. The overall system also responds to the draft standard VDE-ST-Li-ESS-001. 2013/03 with significantly more extensive requirements for functional safety of the whole system through the fully integrated system design as well as the pre-assembled cable with special polarized plugs are installation and user error (contact , reverse polarity and short circuit) virtually eliminated.
Both the battery pack and the whole system are designed for maximum safety and externally audited and certified by the VDE. Professional logistics partner and a special logistics concept for each target country to ensure consistently high standards of safety during storage and transport, in addition, they also enable the secure exchange of battery packs. too modular SMA structured storage systems based on the Sunny Iceland battery inverter and externally connected batteries meet the highest safety standards: systems with lead-acid batteries are generally safety-uncritical to evaluate and for many years around the world. For this, there are proven norms and standards, which of course meets all SMA. For Li-ion batteries SMA refers to the publicly accessible compatibility list that includes many well-known manufacturers. The batteries of these manufacturers meet high quality and safety requirements, are intrinsically safe and have been tested by SMA for compatibility.
