Cactos is the most cost-effective and hassle free electricity storage system on the market. It works automatically in the background, providing benefits to the client whilst stabilizing the national electricity grid at the same time. Watch the video to see how Cactos works in practice.

What’s in it for you

No matter what kind of business or property you run and where, it’s normal for localised energy consumption to vary throughout the day. These four usage benefits will help navigate the grid while saving you time, energy and dollars. And the best part is that Cactos Spine does them for you automatically on the background.

Smart shifting – charging when cheap, unloading when not.

If you run a business or property that doesn’t operate 24/7, your energy demand only rises during working hours. Cactos One charges when electricity is cheap and discharges when you need it most during the expensive hours. This way you you can lower the electricity bills.

Storing energy – for the days when the sun don’t shine.

Cactos One stores locally produced green electricity, such as from solar panels, and uses this emission-free electricity during periods when it’s most needed – cloudy, windless days or when energy prices are especially high. This gives you greater energy independence.

Back-up power – zero disruptions to your operations.

Cactos One acts as an active backup power source, anticipating future events using AI and machine learning by continually monitoring  live and historic data. Like a crystal ball, it can prepare for power outages in advance, ensuring no loss of electricity at your facilities.

Peak shaving – leveling out peaks in electricity consumption.

When the localised consumption causes a significant spike in the load curve, you could end up with an imbalanced grid and a higher energy bill. Cactos One levels out those load spikes for you by using stored electricity without disruptions to your schedules or production.

The dynamic duo

Cactos One together with Cactos Spine optimise and manage your energy consumption needs, without you having to lift a finger.

The unit you didn’t know you needed.

Spiralling costs and market turbulence have become everyday topics. Cactos One energy storage units back up your business or property by enabling access to the most affordable and consistent energy available 24/7. The units are built using fully operational, recycled electric vehicle batteries, further reducing environmental impact.

Whether you run a small, local business, represent a governmental entity or an industrial enterprise, Cactos One can help you store and optimise your energy, offer backup and cut costs just by running in the background. It’s the unit you now know you need.

A dashboard to make you look smart.

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.
