Unrivaled Capacity & Industrial Integrity

The Storagedock ES16.4K (51.2V / 320Ah) is designed for high-demand environments where maximum energy density and reliability are non-negotiable. It is constructed with bolted Grade A LiFePO4 Prismatic cells clamped at 5000N and protected by MICA-based dividers to ensure ultimate structural and thermal stability. Providing 13.2kWh of usable energy at 80% Depth of Discharge, it is built to sustain heavy industrial loads with a 4,000-cycle service life.

Comprehensive Smart Monitoring Suite

Managing a high-output system is effortless with the ES16.4K’s integrated intelligence. The unit features a 3-page color touch screen for real-time on-site monitoring, alongside a Bluetooth App for mobile access on Android and iOS. For seamless professional integration, it includes CAN-bus communication fully optimized for Victron Energy ecosystems, delivering precise SOC (State of Charge) and SOH (State of Health) data while logging all historic performance parameters.

Advanced Safety & Massive Scalability

System safety is prioritized with a high-capacity 300A BMS and an integrated 300A circuit breaker with trip function. To maintain the health of the 320Ah cell pack, a 3A active cell balancer works continuously to prevent voltage drift. For large-scale infrastructure, the system is exceptionally scalable, allowing up to 8 units to be connected in parallel to create a monumental 131.2kWh energy bank. The unit is housed in a rugged polymer-coated steel shell with a galvanized steel internal cell pack, suitable for professional wall or floor mounting.
