ESS (Energy Storage System) is an energy storage device that can contribute to  

the improvement of energy utilization efficiency, the utilization of new and renewable energy, 

and the safety of the power supply system by storing and supplying when using less electric energy when needed.

INCELL's Energy Storage System (ESS) uses Samsung SDI's high-performance ESS 

dedicated cell to ensure high efficiency, long life and excellent safety.

PV (photovoltaics) is solar power that converts sunlight directly into 
electrical energy using solar cells without the help of a generator.
It is eco-friendly due to no environmental pollution, can be installed 
in various sizes from small to large, and is easy to maintain.
