Features from Innovation

· At least three times more power generation than conventional solar power (compared to module capacity)
· 100% Power available of maximum load inverter capacity and solid operation with module capacity level
    (40% of inverter capacity)
· Over 15 years of battery life by simultaneously charging and discharging
· Parallel connection of basic modules enables single-phase and three-phase power supply
· 100% automatic problem-preventive system with battery DOD setting
    ( Enable to restart after 5 ~ 10 minutes from insufficient battery power level)
· Engine stop when the vehicle stops and restart when the vehicle starts
    (Inverter in operation only at the time of load)
· No heat and little EMR (little electromagnetic radiation) on Solar cells, batteries, and inverter equipment.
· Easy operation with automatic design, very low repair works and low A / S cost
· Ideal for use in independent power grid (easy to follow up power load)
· Reduced site requirement by 40 ~ 50% compared to the same power generation, easy to install,
    and easy expansion.

Benefits

· Sustainable business growth of ESS market to be expected.
· Sustaining New and renewable power generation market even without government subsidies
· Contributing to the achievement of a 37% GHG emission reduction target in 2030
· Contributing to the fundamental energy conversion technology innovation of related academia
    and industry and international standards and especially in renewable energy industry.

ESS Integrated Business Concept
