LG Chem 6.5 kWh LV



LG Chem 6.5 kWh LV

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

The RESU6.5 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. 6.5kWh is big enough to offset the late afternoon/evening energy use of an average household. Smaller households could cover evening and early morning electricity needs.

This new RESU generation features 4200 watts continuous power and DC round-tripefficiency of 95% while ensuring 80% of capacity retention after 10 years, and consequently comes with a 10 year warranty.
