The story of ChargeBlock, from our origins to our future vision.

From container to battery storage
ChargeBlock was founded with a clear mission: to make battery storage more innovative, compact, and scalable. We build on the 25 years of experience from Unit45 Group – a leading specialist in custom containers, now with 30,000 containers in the lease fleet. From that experience, we saw how the energy market was becoming increasingly complex: high grid management costs, fluctuating prices, and limited flexibility present major challenges. At the same time, we saw a battery market full of white-label solutions, lacking control over quality or long-term reliability. That needed to change. As close collaboration partners with Unit45, we leverage their experience in container development – from complete hospital bed units to sustainable living solutions in containers – and started in 2022 with the development of our own battery containers, specifically focused on grid integration combined with smart energy management.

Complete control over quality
We deliberately chose to have our own product line with full control over design, development, production, and service. The battery containers are developed in the Netherlands in collaboration with a specialist in maritime and industrial electrical engineering, and assembled in China with leading manufacturers like CATL. We carry out twelve on-site quality checks per year ourselves and have our systems certified by TÜV Rheinland according to the strictest European standards. While other suppliers depend on external parties and therefore lack control over the supply chain, ChargeBlock retains full control. We keep batteries and inverters in stock, allowing us to respond quickly to malfunctions. Our customers have a single point of contact in the Benelux, with service and maintenance guarantee.

Preview: from local to global
Our ambition extends beyond the Benelux. Within five years, we aim to be a leader in integrated battery storage solutions for industries, businesses, and households. With our expertise in containers, dedicated production line, and technological collaborations, we aspire to expand beyond Europe to markets like America and Australia, where we have already established a foothold through Unit53 and Unit48. At the same time, we continue to invest in collaboration with grid operators, energy communities, and smart software platforms. Because battery storage is more than just technology: it requires systems that adapt to changing grid requirements, pricing mechanisms, and the energy transition. ChargeBlock is building reliable, scalable solutions that are ready for the future of energy.

Why we do it differently
We do it differently because the energy market demands it. Smarter, more independently, and with an eye on the practice of tomorrow.
From container expertise to battery storage
We are not battery sellers who just move boxes. ChargeBlock is built on 25 years of container expertise from the Unit45 Group. We translated that knowledge into smart, scalable battery storage. Not a white-label product, but a unique solution for a market that deserves better.
Complete control over quality
ChargeBlock develops its own battery containers together with an electrical specialist, conducts 12 quality checks per year, and collaborates with CATL and TÜV. Thanks to our stock in the Benelux and a single point of contact, we guarantee fast service and complete control.
Compact, powerful, and collective
We do more with less. Up to 3.2 MWh in a single 20ft container – plug-and-play and ready for action. Our systems are cyber-secure and built with Tier 1 components. And for home use? We offer smart home batteries with AI through Sunsynk, suitable for dynamic contracts; EPEX and emergency power – reliable and efficient.
Growing with vision and scalability
ChargeBlock thinks bigger. We are building a European standard and taking steps towards America and Australia. Our solutions are scalable, future-oriented, and designed to adapt to grid congestion, price fluctuations, and the energy transition.
From the first impression to the last link: we deliver the difference.
