LG Electronics Inc. on Thursday unveiled a new energy storage system (ESS) designed especially for solar power plants with smaller capacities.

LG's "all-in-one ESS" for 100 kilowatt solar power plants brings together a power conditioning system, power management system, battery, cooling and heating system, fire extinguishing system and other equipment. LG said it also offers a three-year warranty for every part of the product.

The package includes a 274 kWh battery, making it capable of storing power that can support roughly 25 households on a daily basis. LG said its ESS is optimized for a 100 kilowatt solar power plant, which can produce about 370 kWh a day.

To enhance safety performance, customers can check the status of solar power plants and ESS in real-time using their PCs or mobile devices. Using a remote-control system, customers are also allowed to control the power conditioning system and battery of the ESS.

LG said the battery also stands out as it maintains 75.4 percent of its performance even after 15 years. The company will also provide a three-year warranty on all parts of the package.

The South Korean government is focusing on eco-friendly renewable energy, and the solar power ESS market is expected to grow rapidly in the country. LG says that solar power plant operators who use the ESS facility can receive five times the Renewable Energy Certification (REC), an incentive system made by the S. Korean government.
