Description

The Dyness STACK100-12S is a twelve-module high-voltage (HV) LiFePO4 battery: 61.44 kWh nominal capacity, 58.37 kWh usable energy (95% DOD). It is the largest single-column configuration the manufacturer recommends – from 13 modules Dyness advises building two columns. Intended for a manufacturing company, a warehouse or an agricultural enterprise with a 50–60 kW solar plant. Indoor installation (IP20).

Capacity and power

Twelve modules operate in the 537–700 V range. Recommended charge and discharge power is 30.72 kW (0.5C), with short peaks up to 61.44 kW (1C) – a 50 kW-class inverter runs between the recommended and maximum rates. The column is full by recommendation: next comes a second column (13S–15S, kit C) or parallel 12S towers (up to 12, 737 kWh).

One 12S or two 6S

The same capacity is also obtained from two parallel 6S towers. A single 12S takes 0.23 m² of floor and one BDU, but requires 2,036 mm of free height (with the 200 mm gap) and a floor that carries 586 kg. Two 6S towers halve the weight and height, but need a second BDU with base and a 300 mm gap on the fan side.

Installation and location

Dimensions 591 × 390 × 1,836 mm, weight 586 kg; the modules stack without cables and the tower is secured to the wall with the brackets supplied. Charging from 0 °C, discharging from −20 °C (with heating – from −20 °C), fan cooling up to 55 dB. Leave 500 mm to other equipment.

Inverter compatibility

In the Dyness list (12/2025) the 12S is marked with Solis S6-EH3P 12–20, 29.9–50 and 75–125 kW, Deye SUN-5K~25K-SG01HP3, 29.9–50 and 60–80 kW, GoodWe GW6-15K-ET-20, GW15~30K-ET and GW40-50K-ET-10, Growatt WIT 29.9~50K-XHU, Kostal PLENTICORE G3 and MP G3, Solinteg MHT, Koyoe, ATESS HPS, Sermatec, Sinexcel PWS1-150~250K, Sunways STH-4~12 KTL-HT-P, Dunext, Livoltek, Megarevo, Sosen and TBB Power. Deye SUN-5K~25K, GoodWe GW6-15K-ET-20, Koyoe, Dunext and Livoltek are marked with the 12S for the last time. Communication is CAN or RS485; whether your inverter is marked for the 12S we check against its label before you order.

Safety and warranty

The warranty is 10 years in Europe with an active inverter connection (3 years without it): at least 70% of usable energy or 181.09 MWh of throughput; accessories and tools are not covered. Twelve modules mean twelve separate aerosol extinguishers, LiFePO4 cells, more than 8,000 cycles.
