We offer a full service, not just a set of batteries. Once your units are set up and running, you’ll gain access to Cactos Spine – our very own energy software through which all of your property’s critical info can easily be tracked in real time via your personal dashboard. You can find system status, consumption and production data as well as other key metrics all in one place.

We like to think of One as the body and Spine as the brain.

What size electricity connection does the Cactos One system require?

 ​The property’s connection size (also known as main fuse size) is often used as the basis for sizing Cactos One units. When the size of the property's connection is at least 100A per installed Cactos unit, the system can be fully utilized.

How big of an energy storage system can Cactos deliver?

The Cactos One system is fully modular and scalable, which means that several Cactos One units can be installed at one site and a system of up to several megawatt hours can be implemented. The ideal size of the system depends on the clients’ individual use case, electrical connection size and consumption profile. 

There is no upper limit to the number of units that can be installed by Cactos and the modular nature allows for the units to be scaled over time, as a client's needs evolve and changes, but allowing for the benefits to be enjoyed from the installation of the very first unit.
