Energy Storage

Growatt's reliable and efficient energy storage systems offer an innovative way to use and store solar energy effectively to increase your energy independence. The high-quality energy storage systems are designed to perfectly meet individual needs and requirements.

What is an energy storage system?

An energy storage system is a system that absorbs energy, stores it and releases it again when required. This process makes it possible to store energy at a time when it is available and cheap, and then use it when it is needed or when the energy source is not available. Energy storage plays a crucial role in the integration of renewable energy sources as it helps to balance the fluctuations in energy production.

Energy storage can be used in different ways depending on the requirements of the system or application. They serve to improve the reliability of the energy supply, support the integration of renewable energies, increase grid stability and balance peak loads. The use of energy storage systems therefore helps to use energy more efficiently and make the energy system as a whole more flexible and sustainable.
