3. Introduction
Finds out that fossil energy sources will be gone soon in future and our environment pollution is getting worse, so as a responsible corporation to our society, we jump into the field of green energy, energy storage system.
Although our history is not long, our R&D team and all of our staff invest all of our capital and energy onto this field.
Finally, our corporation is the only national group in Korea who builds every component of ESS system and furthermore upgrades new design of ESS.

ESS
: ESS is basically composed of power-transfer system, secondary cell, and BMS.
Also, we can operate these three components mentioned above to manage BMS and Controller.
To operate User Interface easily, we are in a process of adding TCT/IP network, PC monitoring software, and multiple Android applications.

8. ESS offers a variety of benefits
ESS compensates for intermittency of renewable energy,
such as wind and solar.
To compensate for wind and sunshine’s variability, energy storage provides stored electricity to the grid and stable power output from renewable energy.
- Reduces output variability
- Improves power quality
ESS enables commercial and residential owners to cut
energy costs.
Electricity stored during off-peak time can be used during on-peak
hours so that home/commercial owners can cut peak demand and
electricity cost. ESS integrated with PV can maximize consumption of
solar energy by using electricity stored off-peak.

9. ESS offers a variety of benefits
ESS helps grid system operators maintain constant
frequency.
Energy storage based on lithium ion battery provides reliable and fast frequency response without being subject to fuel prices and with zero emissions.
ESS can be used to defer transmission and distribution network upgrades and investment.
Using energy storage, upgrade to transmission and distribution
networks can be deferred by smart management of the local
peak demands.
- Transmission support
- Transmission congestion relief
- Area / Frequency regulation

10. ESS of Advantage ON-LINE UPS System Grid Connected System
A system that provides uninterruptible
power during an emergency by operating
an integral battery and an inverter after
being supplied with normal AC power.
A system that benefits from Electrical
Grid by sending AC power that is conve-
rted From DC power produced by
Photovoltaic Power panels through an
inverter.
