Your questions. Our answers.

Yes. Even with low basic consumption, a storage system is worthwhile because excess solar power is stored and used later – for example, in the evening or at night. This increases your self-consumption and reduces your electricity costs.
In most cases, no. Our balcony power plants are designed as plug-and-play systems and can be easily set up and connected to a suitable socket. Please observe the applicable legal requirements in your country.
Yes. Many of our storage systems, such as those from Anker or Marstek, can be expanded with additional batteries. This way, your system can easily grow with your energy needs.
This depends on your power consumption and your requirements. Anker offers particularly smart features and expansion options, Marstek impresses with excellent value for money, and Conow is a strong solution for price-conscious buyers. We would be happy to advise you personally.
Depending on the model, our energy storage systems have an integrated emergency power function. In the event of a power outage, selected devices can continue to be powered directly by the storage system. The available power depends on the specific model.
This is model-dependent. Depending on the storage unit, two to four solar modules can usually be connected. You can find the maximum number of modules and power in the technical specifications of the respective product, or we would be happy to advise you on your selection.
