Robust High-Capacity Energy Storage

The Storagedock ES7.4K (51.2V / 144Ah) is engineered for maximum reliability and power density. Built with bolted Grade A LiFePO4 Prismatic cells clamped at 5000N and protected by MICA-based dividers, this battery is designed for extreme durability and thermal stability. With 5.92kWh of usable energy at 80% Depth of Discharge and a rating of 4,000 cycles, it is an ideal choice for high-demand off-grid and backup applications.

Intelligent Monitoring & System Control

Equipped with a 3-page color touch screen, the ES7.4K provides instant on-site access to critical performance metrics. For advanced management, the battery includes a Bluetooth interface for mobile app connectivity (Android and iOS) and CAN-bus communication specifically designed for Victron Energy GX devices. The system continuously records historic parameters and features integrated SOC and SOH communications for precise battery bank management.

Advanced Safety & Industrial Scalability

The ES7.4K features a high-output 150A BMS and an integrated 125A circuit breaker with trip function. To ensure long-term cell health, a 3A active cell balancer works continuously to maintain voltage equilibrium across the pack. For larger infrastructure needs, up to 8 units can be connected in parallel, creating an expansive 59.2kWh energy storage system. The unit is housed in a rugged polymer-coated steel shell with a galvanized steel internal cell pack, suitable for wall or floor mounting.
