A Note About Green CATCH and Batteries
Yes, Green CATCH does work with batteries, but it’s important to know that homes with batteries often desire more than just simple energy storage.

If you’re planning to: join a VPP, use dynamic or flexible tariffs, or take part in wholesale market offerings like Amber, then Green CATCH may not be the right fit.

For these setups, we strongly recommend choosing CATCH Control. It’s far more flexible and is purpose-built for the future requirements of modern battery systems.
