Description
Dyness STACK280 | Stackable Commercial & Industrial LFP Battery System
Rackless, cable-free stacking energy storage built for small commercial and industrial scale.
The Dyness STACK280 uses high-capacity 280Ah LiFePO4 cells in a rackless, stackable design that's simple to plug and play. Scale from a single stack up to 12 clusters in parallel — reaching a maximum system capacity of 2.58MWh — while a built-in aerosol fire extinguisher detects and suppresses fire hazards within 5 seconds for all-around electrical safety.
