Dyness STACK100 S51100 is the 5.12 kWh battery module used to assemble a modular STACK100 high-voltage energy-storage system. It combines 100 Ah LiFePO4 cells with a stackable 47 kg indoor enclosure for residential, commercial and industrial projects.

One module, not a complete storage system

This item contains one S51100 battery module. A working STACK100 cluster requires the correct Dyness BDU and base, cover, three to fifteen identical S51100 modules, a compatible inverter, protection and professional commissioning. The resulting cluster provides 15.36 to 76.8 kWh nominal energy.

Configuration and compatibility

STACK100 systems use three to fifteen modules in one cluster. Parallel clusters are possible only where the current Dyness design documentation, inverter compatibility list, firmware and site protection support the exact arrangement. Compatibility is confirmed for every order.

Delivery and installation

The module is held in European supplier stock. Availability is confirmed when the order is accepted. Freight, unloading and installation are quoted for the destination. The IP20 enclosure is intended for a clean, dry indoor technical area, and the 47 kg module requires safe mechanical handling by qualified personnel.
