SMA Solar Technology AG (SMA) and LG Chem Ltd. have partnered to develop a flexible solution to store photovoltaic power and thus reduce the consumer cost of electricity by more than 80%. The new storage solution is tailored for use in private households and comprises SMA’s Sunny Boy Storage 2.5 battery inverter and LG Chem’s RESU 10H and 7H storage units. Going forward, the two market leaders are planning to expand the focus of their collaboration on utility-scale storage solutions with the SMA Sunny Central Storage battery inverter.
The new high-voltage storage solution with the RESU 400V lineup and the Sunny Boy Storage battery inverter will be available with 7kWh and 10kWh storage capacity. Thanks to AC-coupling, the solution is extremely flexible, and all SMA PV systems are “storage-ready” regardless of the installation date. The system can be adjusted to meet individual customer needs and can be expanded at any time. It is easy to install and can be used both with new and existing PV systems. Customers that want to make use of all the advantages of a flexible system, but prefer to use low-voltage technology, can choose a storage solution that combines the low-voltage variant of the RESU storage unit with the Sunny Island battery inverter from SMA.
In addition, the online portal Sunny Places gives users of both storage solutions a transparent overview of their home, giving them a view of their household energy flows and access potential savings. And with the Sunny Home Manager, the system can be integrated into a comprehensive energy management system, if needed.
The storage solutions from SMA and LG Chem will be available in Europe and Australia December 2016.
