Voltenum.
The battery as smart energy source
Complete solutions for installers, private individuals and businesses.
Voltenum is the complete supplier of sustainable batteries, inverters, advanced software, and complementary solutions, fully tailored to the needs of businesses and their customers.
Safe & Sustainable
Our LiFePO4 batteries are safe and have minimal environmental impact due to their lithium iron phosphate composition.
Powerful
Thanks to our unique high-voltage solution, even the largest energy consumers, such as air conditioning systems, heavy charging stations, and heat pumps, can be powered efficiently.
Stable
Thanks to the chemical composition of LiFePO4 lithium, customers can rely on stable performance. Even after 6,500 discharge cycles, the batteries still retain more than 80% of their original capacity.
Smart
Thanks to our advanced software, users gain better insight into their energy consumption and can distribute it more efficiently. With a dynamic energy contract, electricity can be purchased at the lowest price when needed and stored for later use.
Certified
Our products meet the highest standards of safety and quality, as evidenced by the European CE mark and the globally recognized TÜV certification.
Easy to Install
We offer training for our installation partners to ensure the safe and professional installation of our PowerBlocks—stackable home batteries—and PowerRacks—the ultimate solution for the commercial market.

Hybrid Inverters
Maximize your battery’s potential with our smart hybrid inverters: safe, user-friendly, and suitable for both indoor and outdoor use.
About Voltenum
Since 2023, Voltenum has been committed to a more sustainable world. In June of that year, extensive research was conducted into the energy market, revealing that information on battery energy storage was scarce in the Netherlands. Advice and products in this field were even harder to find.
This prompted an in-depth study into energy storage technologies, energy markets, and related developments.
Later that year, Voltenum was officially founded.
The mission is clear: contributing to a more sustainable world through smart energy storage. This is summed up in the slogan:
“The battery as a smart energy source.”
Become a Partner?
We exclusively collaborate with certified partners to ensure our battery solutions are installed safely and professionally, providing an optimal user experience.
Energy Management System
An Energy Management System (EMS) is essential for the optimal operation of your energy storage system. It makes a battery smart by ensuring intelligence is deployed at the right time and place. A well-designed EMS is integrated with weather forecasts, provides real-time electricity price data, understands household or business consumption profiles, and prioritizes energy distribution where it is needed most.
The Voltenum Connect app offers insights, efficiency, and a superior user experience.
Download our app below and experience the convenience of our all-in-one EMS for both private and business customers.
