Build the energy solutions of the future


As wind and solar power become more common, the need for energy storage is growing. At Cactos, we’re here to support this transition. Our battery storage systems capture excess energy when supply exceeds demand - helping to stabilize the electricity grid.

We help our customers get more value from their local energy production while protecting them from price fluctuations and outages - so they can focus on their most important tasks.

Straight out of Kempele

We design and manufacture our energy storage systems and their battery modules at our factory in Kempele.

Our administration and development teams are based in Vallila, Helsinki, where experts in software development, marketing, sales, finance, and electricity markets work closely together to drive innovation.

Beyond Finland, our international sales teams are building our presence in Sweden, Norway, and the Netherlands, bringing our solutions to a growing global market.

Join our growing team, where a relaxed atmosphere, the freedom to make an impact, and a passion for developing leading energy solutions bring us together.
