About us

Sometimes you just know: things need to change. After working together for years we, Mathijs and Kelvin, decided to take a different path. We wanted to build something that truly energizes us, both literally and figuratively. That idea led to the creation of Slimme Energieopslag.

Our mission is simple: to make sustainable energy smarter and more user-friendly. We believe that everyone should have access to reliable and future-oriented energy storage. The world has become less predictable in recent years—from pandemics to political tensions and resource shortages. This shows how vulnerable our energy supply can be. That is exactly why we believe everyone should have the opportunity to store energy intelligently: so you are less dependent on others, can make better use of renewable energy, and gain more control over your own future.

Store, Save, Be independent

What we stand for

The energy market is constantly evolving. But let’s be honest: it’s also a market where it’s easy to lose sight of the bigger picture. Fast-talking salespeople and solutions that don’t always fit the customer. We do things differently.

What we believe in

Sustainable solutions that truly contribute to the future. Reliability—saying what we do and doing what we say. Thinking along with you, not a one-size-fits-all story, but advice tailored to your situation.

What we do

We make energy storage accessible and easy to understand. From plug-and-play home batteries to power stations and everything that comes with them. We deliberately work with a select number of brands—not to limit the offering, but to ensure quality.

Our solutions

Our solutions are ideal for people with solar panels who are concerned about—or preparing for—the phase-out of the net metering scheme in 2027. With a plug-and-play home battery, you can use more of the energy you generate yourself, making you less dependent on changing regulations.

In addition, our systems offer more than just storage. They are suitable for smart energy trading, allowing you to recoup your investment more quickly. At the same time, you contribute to a more stable energy grid—something that will only become more important in the future.

Whether you are just getting started with energy storage or already know exactly what you’re looking for, we support you from A to Z with a solution that works.
