LG Chem 6.4kWh
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. Of course, the battery pack can also be utilised in an off-grid situation.
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.
