If you make the cells themselves, why not make the energy storage system to go around them?
LG Chem has announced the formal launch of its residential battery systems into the North American market, with initial capacities up to 9.8 kWh.

These energy storage system are designed for AC- and DC-coupling, and the Korean manufacturer says it is working hard to secure compatibility with third-party components, such as inverters.
According to LG Chem, the company has been awarded 82 projects from 28 global automotive OEMs as of September 2016, and has already deployed many Gigawatt-hours of global stationary battery projects already
"The launch follows successful completion of UL certification and represents LG Chem’s initial foray into the North American residential market. Since 2013, LG Chem has been at the forefront of providing residential battery storage (RESU) systems and has earned a strong reputation for quality, reliability and dependability. The commitment to delivering quality products and services has resulted in excellent annual growth and new business throughout Europe and Asia, especially in Germany, Italy, the UK, as well as Japan and Australia. The residential systems’ pioneering features were recognized with the ees AWARD 2016 and, in the fast-growing Australian market, LG Chem has quickly established itself as the market leader according to EuPD Research.
LG Chem’s North American residential battery range offers AC- and DC-coupled solutions with capacities up to 9.8 kilowatt hours (kWh). Two voltage options are available, pre-matched with compatible inverters and suitable for both indoor and outdoor installation:
The 400V RESU10H (9.8kWh) product is compatible with SolarEdge’s StorEdge™, which is a DC coupled storage solution based on a single inverter for both PV and storage. Additional inverter compatibility options will become available later in 2017 to provide homeowners with a range of pre-tested solutions from the industry’s leading suppliers.
- Low-voltage 48V: with capacities of 3.3, 6.5 and 9.8kWh; and,
- High-voltage 400V: with capacities of 7.0 and 9.8kWh.
LG Chem’s residential batteries will be available via a number of leading solar/storage providers in North America. Following last year’s announcement of a partnership with LG Chem, Sunrun – one of the leading U.S.-based residential energy system providers – will be supplying LG Chem’s RESU systems. Sunrun already has installed initial systems in both Hawaii and California. Additional distribution channels are in advanced negotiations and will provide coverage to all U.S. states and Canadian provinces."
Peter Gibson, Head of ESS Sales for LG Chem in North America said:
“LG Chem’s entry into the North American residential battery market is based on much planning, product development and system testing. We’re confident that our experience gained in Europe and Asia, coupled with strong inverter and distribution partners, will deliver exceptional performance and reliability for our residential customers in the U.S. and Canada. Customers can now enhance the benefits of their residential solar systems by using our batteries to maximize consumption of solar energy, and to use the batteries as a dependable source of energy during grid interruptions.”
