Energy Storage Solutions

Energy Storage Solutions (ESS) is an application that has been studied extensively. It stores the energy (electricity) from different power generation elements (coal, nuclear, wind, solar, etc.) in a variety of forms like electrochemical storage (battery), mechanical storage (compressed air), thermal storage (molten salt), etc. In this guide, battery energy storage system connected with the solar inverter system will be targeted.

BESS (Battery Energy Storage System) is widely employed in both residential and commercial cases. In residential applications, a BESS serves as a backup power supply, preventing unexpected power outages and contributing to cost saving by shifting electrical energy from low-value to high-value periods. In commercial applications, which involve larger systems, BESS can efficiently store and manage the free and clean energy produced by solar inverter, achieving low-carbon emissions. Another key attribute of BESS today is its ability to reduce the grid pressure caused by growing demands of EV charging.

Lithium-ion battery, which is known as the major part of electrochemical storage system, has high power/energy density, high roundtrip efficiency, compact footprint, and flexibility for expansion. The Li-ion battery is a relatively mature technology that has benefited from more than three decades of commercial development, which makes it a reliable and low-cost solution. It can be regarded that the continuous cost down of Li-ion battery has strongly accelerated the development of energy storage.
