Dyness S51100 Pro High Voltage Storage Battery 5.12kWh LiFePO4 Heated
The Dyness S51100 Pro is the battery module of the STACK100 Pro series, a high voltage storage system with LiFePO₄ cells intended for residential and small commercial PV plants. Each module provides 5.12kWh nominal (4.864kWh usable) at 51.2V and 100Ah, and always works together with the SBDU100 Pro control unit and its base.
The modules stack one on top of the other without cables: from 3 to 15 modules form a cluster of 15.36 to 76.8kWh with an operating voltage of 134.4–864V, and up to 12 clusters can be connected in parallel. The system interfaces over CAN/RS485 with high voltage hybrid inverters — the manufacturer lists Solis, GoodWe, Growatt, Deye and Solinteg — and is monitored via Wi-Fi and app. The heated version offered here extends charging down to −20 °C, useful in unheated technical rooms.
Key features
Expandable 5.12kWh moduleFrom 3 to 15 modules per cluster, for a capacity of 15.36 to 76.8kWh; up to 12 clusters in parallel.
Cable-free stackingModules are connected by stacking them, cutting installation time and wiring errors.
LiFePO₄ cells with 95% DODLithium iron phosphate chemistry with 95% depth of discharge and an expected life of at least 8,000 cycles.
Heated versionWith the heating option, charging is allowed from −20 °C to +55 °C, against 0…+55 °C for the standard version.
Charge and discharge up to 1CRecommended power of 2.56kW (0.5C) and maximum of 5.12kW (1C), with a discharge peak of 125A for 2 minutes.
Built-in safetyVent valve, aerosol fire extinguisher and temperature probe; IP66 protection rating and CE-EMC, CE-RED, IEC 62619, IEC 63056, IEC 62477, UN38.3 certifications.
