Samsung SDI unveiled two residential energy storage systems (ESS) at Intersolar Europe 2015 in Munich, Germany. The new 5.5kWh and 8.0kWh units join the existing 3.6kWh system.
The new residential EES integrates the PV inverter, battery PCS and Li-ion battery. As a DC system, the Samsung All-in-One system is highly efficient in storing solar energy into electrical energy because PV generation in form of DC is stored in battery without DC/AC inverting.
The battery in the All-in-One is the same battery used in German premium EV cars and grid-scale energy storage system in Schwerin, Germany. Samsung SDI says that it is the only Li-ion battery company without a single recall. Samsung SDI assures long- term product warranty for 5 years, with a performance guarantee of 10 years.
