Expansion modules allow existing solar energy storage systems to be easily and safely expanded with additional batteries. These modules allow users to adapt the capacity of their system to growing energy demands without having to install a completely new battery pack. The expansion units are compatible with the manufacturer's own battery series, ensuring compatibility, efficient communication and system stability.

The modules are ideal for those who want to increase the energy storage capacity later, for example due to the introduction of new consumers or electric vehicles. The expansion not only results in greater energy reserves, but also in more flexible and sustainable operation in the long term. The installation of the expansion modules is quick and the battery system automatically recognizes the new units, so the system continues to operate optimally.
