6.4kWh battery storage system

The LG Chem is a Residential Energy Storage Unit (RESU) featuring a 48V (nominal 51.8V) lithium ion battery with integrated battery management system.

The battery is designed to tie in with a grid connect solar system to increase self-consumption and savings. An additional inverter (e.g. SMA Sunny Island) is also required.

The LG Chem has a life expectancy of over 10 years (and a ten year warranty to prove the point). It can be cycled (discharged and re-charged) 6000 times to 90% Depth of Discharge (DoD), meaning only 10% left in the battery. In $/kWh, this is possibly the cheapest battery on the current battery market.

The battery pack is big enough to offset the evening energy use of an average household. Smaller households could cover evening and early morning electricity needs.

The battery's peak rating is 5kW (@25°C) which should handle the kettle, the toaster and a third energy hungry appliance. Additional peak power will be supplied by the grid if available.

LG Chems can be easily expanded by adding expansion battery packs (of 3.2kWh) to 9.6kWh or 12.8kWh total energy storage.
