Flexcube-250E portable Battery System 466kWh

AlpSolarr FlexCube-500E Modular Energy Storage & Microgrid System

The battery can be supplied with your own design. Please contact your sales manager for options.

AlpSolarr's FlexCube-E is an advanced modular energy storage system (ESS/BESS) specifically designed to provide reliable power in situations where the electricity grid is unreliable, absent or unstable, but also ideally suited for industrial, commercial or micro-grid applications.

Key Features

Modular container construction : The FlexCube is designed as a compact container unit, making transport, installation and commissioning relatively simple and flexible.

High capacity & expandable : Typical configurations start at around 500 kW/466 kWh and can be scaled up to 699 kWh or more. Parallel expansion is possible, allowing for capacity tailored to the project.

All-in-one system : The container contains all necessary components — battery packs, battery management system (BMS), power conversion system (PCS), controller, cooling, safety and fire protection, etc.

Flexible power sources : The system can be connected to the electricity grid, solar panels (PV), diesel generators, or a combination of these. This allows for both on-grid and off-grid operation.

Supporting heavy and varying loads : Thanks to its robust design and smart load management, FlexCube can handle impact loads such as water pumps, drilling rigs or industrial machinery.

Reliability & ease of maintenance : Thanks to the modular and integrated design, maintenance, monitoring and management are simpler than with individual systems.

Typical applications & scenarios

The FlexCube-E is ideally suited for situations and sectors such as:

Locations without a stable or existing energy network (remote areas, construction sites, construction projects, mobile installations)

Microgrids, industrial enterprises, mining, oil & gas, infrastructure projects where reliability and flexibility are crucial.

Combinations of solar energy (PV), diesel generators and battery storage to achieve sustainable, hybrid energy supply.

Projects with varying or heavy energy demands (pumps, machines, tools) where peak loads and load variations occur.
