FLEXIBATT MAXI | MODULAR BATTERY STORAGE UP TO 50 KW

Modular and scalable energy storage for civil off-grid applications. The FlexiBatt MAXI Hardcase is a powerful and modularly expandable battery pack in a robust NANUK Hardcase format – designed for civil energy applications that require flexibility, adaptability, and long-term scalability.

This solution is more than a single battery system: it forms the foundation for custom off-grid energy infrastructures that grow with the demand. FlexiBatt MAXI is hence ideal for projects that start today and need more power, longer runtime, or additional functionality tomorrow – without complex repurchasing or extensive system adjustments.

Modularity as a core principle. FlexiBatt MAXI has been designed from the ground up as a modular energy system. This means: individual units can be combined, added, or replaced to precisely match the overall performance to the needs – from small mobile applications to extensive autonomous energy islands. Thanks to standardized interfaces and uniform hardcase design, additional modules can be easily and safely joined, transported, or expanded on-site. This flexibility makes FlexiBatt MAXI a practical solution for a wide range of civil use cases.

FLEXIBATT MAXI – SCALABLE UP TO 50 KW

FlexiBatt MAXI is designed for scalable energy requirements and can be modularly expanded up to a total output of 50 kW. By connecting multiple units, powerful off-grid energy systems can be created that adjust precisely to the respective needs. This scalability allows for use in both smaller temporary applications and extensive civil infrastructures with high energy demands. Power and capacity can be gradually increased – without changing systems, without complex reinstallation, and without operational interruptions. Thus, the energy supply grows with the requirements while remaining flexible, future-proof, and economical.

The scalability of FlexiBatt MAXI makes it possible to realize energy systems of any size. You start with a base unit and can add additional modules as energy demands increase – similar to a building block system. With FlexiBatt MAXI, you can:

create smaller energy systems for mobile workplaces
provide medium capacities for events or projects
develop extensive off-grid infrastructures for long-term deployments

The modular expandability also means that the system can be flexibly adjusted during operation – without downtime and without complex reinstallation.

FLEXIBATT MAXI – UPS-COMPATIBLE

The FlexiBatt MAXI is capable of UPS and can be used as a uninterruptible power supply. A UPS ensures that connected devices continue to receive power without interruption during a power outage or voltage fluctuations.

During regular operation, the FlexiBatt MAXI is connected to the power grid or an external energy source. If this source fails or becomes unstable, the system automatically and without delay takes over the power supply. Critical devices such as IT systems, communication equipment, controls, or medical technology remain operational at all times.

Due to this UPS function, the FlexiBatt MAXI is particularly suitable for civilian applications with high demands for supply security, where failures, data losses, or operational interruptions must be avoided at all costs.

FLEXIBATT MAXI - WELL-THOUGHT-OUT DURABILITY

All FlexiBatt MAXI units are housed in a shatterproof, weatherproof NANUK Hardcase, making them particularly robust and weather-resistant. The sturdy casing protects against impacts, splashes, and dust, making it suitable for use indoors and outdoors – even under harsh conditions.

Advantages of the modular design. With FlexiBatt MAXI, users get:

flexible energy configuration that grows with demand
easy expandability without interrupting operation
customizable capacity, for small to large projects
transport-friendly design within the Hardcase
quiet, emission-free energy without fossil fuels
compatible system architecture for future applications

Future-proof, decentralized energy for civilian applications
FlexiBatt MAXI combines modularity, scalability, and mobility into a powerful energy storage solution for everyday civilian use.
Whether for temporary deployments, long-term infrastructure projects, or flexible energy supply at remote locations – FlexiBatt MAXI can be adapted, expanded, and developed at any time. With this solution, users create future-proof, environmentally friendly, and off-grid energy systems that meet the demands of modern operational scenarios – today and in the future.
