RCT Power Spring Promotion


Expand your storage system to up to 6 RCT Power battery stacks by May 31, 2024 and benefit from generous cash-back. Get more efficiency from the 2024 test winner now!

The available storage capacity is often not sufficient to cover energy requirements, which can lead to unnecessary electricity costs. Fortunately, there is a solution: with the RCT Storage Spring, you can easily upgrade your RCT Power storage system and even get money back.

So take advantage of this opportunity and take part in the RCT Storage Spring! 

We want everyone to be able to benefit from the campaign. That's why this short-term offer is also available for new installations!
