Description

Overview

The Dyness STACK100 Pro battery module (model S51100 Pro) is a 5.12 kWh, 51.2 V lithium iron phosphate (LiFePO₄) building block for the STACK100 Pro high-voltage storage system. Designed for residential and small commercial & industrial applications, its rackless, cable-free stacking design makes installation plug-and-play.

Stack 3 to 15 modules on a single STACK100 Pro BDU and base (sold separately) to build a 153.6–768 V cluster of 15.36–76.8 kWh, and connect up to 12 clusters in parallel for up to 921 kWh. With full 1C charge/discharge, IP66 protection and a cycle life of ≥8000 cycles, the STACK100 Pro suits demanding duty such as grid frequency regulation and EV charging stations.
