15-Year Warranty for Domestic Li-ion Energy Storage Modules

June 15, 2014 by Jeff Shepard

Saft Power Systems Li-ion Energy Storage Systems (ESS) are designed to ensure the effective grid integration of solar PV at all levels from enhancing domestic self-consumption through to megawatt scale installations that support the operation of large PV generation plant as an integral element of power networks. Saft is now offering a warranty extension of up to 15 years for Synerion® Storage Systems integrated into Bosch's BPT-S 5 Hybrid intelligent energy management and storage solution.

The recent Intersolar Europe event confirmed the current high level of interest in residential ESS solutions that enhance domestic self-consumption with news of the Euro 50 million support program by the German Ministry of Environment (BMU). Saft claims to be ideally positioned to respond to the particular needs of this fast growing sector through its leadership in Li-ion technology established by an extensive, long-term product test and development program. This program has shown that Saft’s VL Li-ion battery technology is superior to other commercially available Li-ion technologies in both calendar life and cycle life. In extended cycling in particular, Saft batteries maintain a high capacity, even after more than 7,000 charge/discharge cycles.

Saft’s domestic scale ESS solutions are based on its Synerion Li-ion battery modules, each of which delivers around 2 kWh energy and up to 4 kW power. A key initiative for Saft at Intersolar Europe was the launch of an optional warranty extension of up to 15 years for the Synerion Storage Systems installed as part of Bosch’s innovative BPT-S 5 Hybrid intelligent energy management and storage solution. This move makes Saft the first manufacturer anywhere in the world to demonstrate this level of confidence in the reliability and long-life of its Li-ion technology by offering an extended warranty.

The technologically mature, fully commercialized Bosch BPT-S 5 Hybrid system, launched in 2012, integrates a solar inverter, an energy management system and Saft’s Synerion modules. It is fully certified and safety tested and Bosch has hundreds of installers trained in the installation of the units.
