RESU6.5 - 6.5kWh battery storage system

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. SolaX, Victron or Fronius) 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.

With the RESU Plus , all new generation 48V models (3.3kWh, 6.5kWh, 9.8kWh) can be "cross-connected" with one other 48V unit of any capacity. All models are floor or wall mountable; the protection class (IP55) even allows outdoor installation; however, RPC recommends a cool location, e.g. inside a brick garage
