Cactos

Energy · Muhos, Finland · Founded 2021

Develops world's first cloud-controlled, distributed battery energy storage system based on recycled EV batteries MoreLess

Cactos is a Finnish startup that offers an innovative energy storage system, providing a new way to purchase and use energy. The company operates in the energy market, serving both residential and commercial clients. Its primary product, the Cactos One, acts as an insurance against electricity price fluctuations and supply uncertainties, while also reducing costs and carbon footprint.

Cactos One operates automatically, requiring no intervention from the user. It intelligently alternates between charging during cheaper hours and releasing energy during peak hours. This helps clients reduce additional costs caused by peak-hour electricity consumption. For businesses that do not operate round-the-clock, this system can significantly cut down energy costs.

Moreover, Cactos One stores locally produced green energy, such as solar power, for days when it is most needed, like on cloudy and windless days when electricity is typically more expensive. This feature reduces the user's dependence on the variability of energy production.

Cactos One also functions as an active backup power source, predicting future events using artificial intelligence and machine learning. It constantly monitors consumption data and weather forecasts to prepare for potential power outages, ensuring that users are never caught off guard by a lack of electricity.

The company's business model is based on selling these energy storage systems. By helping users save on energy costs and providing a reliable backup power source, Cactos generates revenue from the sales of its product.
