Extreme Capacity & Dual-Module Engineering

The Storagedock ES24K (51.2V / 468Ah) is the pinnacle of high-density energy storage, featuring two internal modules working in tandem to provide 19.2kWh of usable energy at 80% Depth of Discharge. Built with bolted Grade A LiFePO4 Prismatic cells and secured with a 5000N clamped force, this unit is engineered for maximum structural integrity. Its industrial-grade construction is specifically designed to handle the heavy throughput required by large-scale 48V power infrastructures.

Intelligent Digital Interface & Monitoring

Despite its massive scale, the ES24K offers precise control through an integrated 3-page color touch screen for real-time local monitoring. The battery is fully equipped for the modern smart-grid, featuring Bluetooth connectivity for mobile app access (Android and iOS) and CAN-bus communication for seamless integration with Victron Energy GX devices. The system continuously logs all historic parameters, ensuring you have a complete overview of the battery’s State of Charge (SOC) and State of Health (SOH).

Industrial Safety & High-Output Scalability

Safety is managed by a high-output dual BMS system (300A x 2) and protected by a dual 300A circuit breaker (600A total) with an integrated trip function. An industrial-strength 3A active cell balancer ensures that even at this massive scale, all cells remain perfectly equalized for longevity. For utility-scale energy needs, up to 8 units can be connected in parallel, creating a massive 192kWh energy reservoir. The unit is housed in a professional-grade polymer-coated steel shell with galvanized steel internal cell packs, suitable for floor-mounted installations.
