Industrial-Grade High-Capacity Energy

The Storagedock ES32.8K (51.2V / 640Ah) is engineered to be the heart of a robust energy system. Built with bolted Grade A LiFePO4 Prismatic cells and a 5000N clamped force with MICA-based dividers, this battery ensures superior thermal stability and structural longevity. Providing an impressive 26.2kWh of usable energy at 80% Depth of Discharge, it is designed to handle sustained high-load applications with ease.

Intelligent Digital Control & Monitoring

Monitoring such a significant energy reserve is made simple through an integrated 3-page color touch screen for real-time local data. The ES32.8K is fully connected, featuring a Bluetooth interface 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 performance parameters, offering detailed insights into the battery’s State of Charge (SOC) and State of Health (SOH).

Maximum Safety & Expansion

Reliability is underpinned by a dual 300A BMS system and protected by dual 300A circuit breakers (600A total) with an integrated trip function. An industrial 3A active cell balancer works constantly to maintain perfect voltage balance across the massive 640Ah cell pack. For utility-scale requirements, up to 8 units can be connected in parallel, creating a monumental 262.4kWh energy bank. The unit is housed in a rugged polymer-coated steel shell with a galvanized steel internal cell pack, optimized for floor-mounted installations.
