A big step for LG Electronics that has recently announced the entry in a new growing market: the sector of energy storage systems (ESS). As the company explains, some renewable energy technologies such as solar and wind deliver their power inconsistently and unpredictably and ESS can play an important role in “smoothing out” the electricity supply from these sources and in order to deliver power when it is needed. LG starts this new path, from U.S. residential ESS market with the introduction of two solutions: an AC-coupled 5.0 kW system for those who already have solar panels of any type already installed and a DC-coupled 7.6 kW system as part of a new installation of LG solar panels – and an expandable battery pack for homeowners gives homeowners more innovative options for their energy needs.
LG ESS works by using “smart energy management” to store excess energy produced from residents’ solar panels for use during hours when no solar energy is being produced, making it available at night or on overcast days. This also allows for less reliance on the public utility grid during times of peak energy consumption when electricity rates are the highest. LG ESS achieves higher efficiency because its DC-coupled ESS converts power more efficiently than AC type ESS units. In a power outage, each LG ESS can store up to four hours of energy and can be scaled up for more storage by pairing with an expandable battery pack.
«In the future – they say from the company – as more storage technology options emerge and the United States transitions to a cleaner energy economy, energy storage is poised to play an even greater role and LG plans to be part of the solution.»
