SMA Solar Technology AG Welcomes Safety Guidelines for Lithium-Ion Home Storage Systems

SMA Solar Technology AG (SMA) welcomes the publication of safety guidelines for li-ion home storage systems by leading associations in the solar, storage and electrical industries. As part of the German Solar Industry Association and the German Energy Storage Association, experts from SMA played a significant role in creating the guidelines. SMA is already working to obtain the declaration of conformity with the new safety guidelines for the Sunny Boy Smart Energy.

More and more people are gaining independence from rising electricity prices through the self-consumption of solar power. Battery storage systems allow them to use as much of the solar power they produce as possible. “With the publication of the safety guidelines for lithium-ion home storage systems, we now have uniform recommendations for manufacturing and operating storage systems for the first time ever, before the completion of the time-consuming standardization process. These ensure additional safety in the use of storage systems as the market is growing,” said Martin Rothert, an expert in storage systems at SMA.

Safety has been SMA’s utmost priority in developing storage systems from the very start. The two SMA storage systems on the market, the Sunny Boy Smart Energy and the Sunny Island, have sophisticated safety concepts. In addition, SMA included the Association for Electrical, Electronic and Informational Technologies (VDE), as the leading institute for electrical system safety, early in the development of the Sunny Boy Smart Energy, the wall-mountable solar inverter with integrated battery. The safety of the entire system, inverter and battery, was tested and conclusively certified by VDE. The Sunny Island battery inverters, part of SMA’s modular Flexible Storage System, carry the GS mark for tested safety issued by VDE. SMA also tested the safety concept of every compatible li-ion battery recommended by SMA.

As a next step, SMA is already working to obtain the declaration of conformity for the Sunny Boy Smart Energy. In the area of flexible solutions based on the Sunny Island, SMA is striving for a declaration of conformity for batteries from leading manufacturers, which will be used in the Sunny Island systems.
