ESS 7.0 / 9.0 / X

The Modular Energy Storage System

ESS 7.0 / 9.0 / X is a new modular lithium-ion energy storage which stores the generated surplus energy into battery modules for a later use. The inverter can then feed this power into the network or the energy storage.

The power is available whenever it is needed: in the evening, at night and at times when there is little or no sunshine. With the ESS 7.0 / 9.0 / X storage system, solar energy users become less dependent on electricity prices and can use their own eco-power whenever they need it.

Cluster solutions

The design of the system is based on a modular principle: Depending on the desired storage capacity, the battery modules can be adapted to the needs of the user. For the recommended configuration of the storage system, please contact us.
