Dyness STACK100 storage

Description

The Dyness STACK100 3S is a modular high-voltage (HV) energy storage system with an integrated BMS, designed for residential, commercial and small industrial sites. It consists of three 5.12 kWh LiFePO4 battery modules (51.2 V / 100 Ah) — 15.36 kWh total capacity, 134–172.8 V operating voltage, 50 A recommended charge/discharge current (100 A max), 95% depth of discharge, ≥ 8,000 cycles, IP20 protection rating. The set includes a BDU control unit, a free-standing stack-type structure, internal communication and power cabling, a built-in Wi-Fi module and an active cooling system; a tower can be expanded up to 15 modules (76.8 kWh), and up to 12 towers can be connected in parallel. The system is intended for storing solar plant energy, backup power and optimising electricity consumption and day/night tariffs: it supports 1C charging/discharging, fast energy delivery, plug-and-play installation, remote OTA firmware updates and integration with hybrid inverters — compatible with Deye, GoodWe, Solis, Growatt, Hoymiles and SAJ. Safety is ensured by thermally stable LiFePO4 chemistry and built-in protection against overcharge, deep discharge, short circuit, overcurrent and overheating, temperature control, active fan cooling and an integrated aerosol fire suppression system. The integrated BMS balances the cells, controls voltage, current and temperature, manages the protections, communicates with the inverter over CAN / RS485, shuts the system down automatically in an emergency and adjusts the permitted charge/discharge power to the battery state, while Wi-Fi and the mobile app provide monitoring of the state of charge (SOC), charge/discharge statistics, energy flows, diagnostics and error logs. Manufacturer's warranty — up to 10 years.
