ETC energy storage solutions will enable you to use renewable energy at home. Energy storage solutions with an integrated security concept offer highly efficient and flexible energy storage at home for private and commercial applications. Thanks to Lithium-ion energy storage modules, the excess home-generated PV power can be stored in battery modules and easily accessible at a later time. Energy surpluses are no longer wasted. Thanks to a power storage system, solar users become less dependent on electricity prices and can use their own green energy whenever they need it.
