BMZ energy storage solutions that make you independent

Using regenerative energies at home - energy storage solutions from BMZ make it possible. Energy storage solutions with integrated security concept are highly efficient and flexible home storage systems for private and commercial applications.

With the modular lithium-ion energy storage, the self-generated, currently not required photovoltaic energy can be stored in battery modules and easily retrieved at a later date. Excess energy is no longer lost.
