LG Chem, which is headquartered in Seoul, is the largest chemical company in South Korea.

The daughter company of LG, LG Chem offers world class solutions for the photovoltaic storage market with exceptional price performance and warranty.

Due to the many years of experience in the development and production of batteries, LG Chem is a leading provider of storage systems. LG Chem develop pioneering energy storage systems for solar installations - the core components of the future electricity market and solar energy supply.

The storage system, supplied by Segen, has a stylish design, is slim and offers at least 6,000 charging cycles and discharge (DOD) of 91%.


Why Lithium Ion?


Lithium Ion or Li-Ion, is an alternative battery type to lead acid. Whilst lead acid, or gel batteries remain cost effective options for grid-backup and off-grid systems, lithium ion is fast becoming the chosen option for many PV applications, offering better functionality and longevity.


The life expectancy of a good quality Li-Ion battery like the RESU6.4 far exceeds lead acid even when charged and discharged every day. Equally importantly they have a higher depth of discharge (DOD), allowing you to use more energy before a further charge is needed. Typically, lead acid batteries only have a 50% DOD, meaning they can only discharge half of their energy stored before needing to be charged again. Lithium Ion batteries typically offer a DOD of around 90%. This also means that when comparing Lead Acid to Li-Ion, you need to compare two batteries with the same usable kWh – not the listed kWh size.


There are many aspects to selecting a battery system and we recommend you read our guides to System Types and Storage Batteries to better understand this technology.


Segen offers the LG Chem RESU6.4 battery as part of it's self consumption portfolio.
