What is Growatt Battery Storage?

Growatt battery storage systems are designed to store excess electricity generated by solar panels, allowing you to use that energy when you need it most—such as evenings, peak tariff periods, or power cuts.

Instead of exporting unused power to the grid, Growatt systems enable you to:

Store your own renewable energy
Reduce reliance on the grid
Lower electricity costs
