Massive Energy Reserves & Industrial Build

The Storagedock ES9.4K (51.2V / 184Ah) is designed for users requiring substantial energy storage without compromising on space or safety. Built with bolted Grade A LiFePO4 Prismatic cells clamped at 5000N and insulated with MICA-based dividers, it ensures maximum structural integrity. With 7.52kWh of usable energy at 80% Depth of Discharge, it is a powerhouse capable of supporting heavy loads in mission-critical environments.

Comprehensive Smart Ecosystem

Stay fully informed with the ES9.4K’s advanced monitoring suite. The unit features an integrated 3-page color touch screen for local data access, supplemented by a Bluetooth App for mobile monitoring on Android and iOS. For system-wide integration, it includes CAN-bus communication fully compatible with Victron Energy ecosystems, providing precise SOC (State of Charge) and SOH (State of Health) data while recording all historic battery parameters.

Unrivaled Protection & Scalability

Safety is managed by a high-performance 200A BMS paired with a circuit breaker with trip function for reliable over-current protection. To ensure the longevity of the cell pack, a 3A active cell balancer works continuously to keep all cells perfectly equalized. For large-scale power requirements, up to 8 units can be connected in parallel, creating an immense 75.2kWh energy bank. The battery is housed in a durable galvanized steel cell pack with a polymer-coated steel shell, designed for professional wall or floor mounting.
