Description

The Dyness STACK100-10S is a ten-module high-voltage (HV) LiFePO4 battery: 51.2 kWh nominal capacity, 48.64 kWh usable energy (95% DOD). It is the 50 kWh-class solution for a company with a 40–50 kW solar plant and a convenient building block: two parallel 10S towers give 102.4 kWh. Indoor installation (IP20).

Capacity and power

Ten modules operate in the 448–584 V range. Recommended charge and discharge power is 25.6 kW (0.5C), with short peaks up to 51.2 kW (1C) – with a 50 kW-class inverter (Solis S6-EH3P(29.9-50)K-H, Deye SUN-29.9~50K, GoodWe GW40-50K-ET-10) the battery works between the recommended (25.6 kW) and maximum (51.2 kW) rates. The tower has room for 2 more modules.

The last variant for 10 kW-class inverters

The 10S is the largest configuration for which the Dyness list (12/2025) still marks Solis S6-EH3P(3-10)K-H(PRO), S6-EH3P(5-10)K2-H(EU) and RHI-3P(5-10)K-HVES-5G, Hoymiles HYT and HAT, SAJ H2-5K~10K-T2, Senergy and Sineng SN5.0~15HT. If your hybrid inverter belongs to this class, the 11S and larger are not suitable for it – further expansion is only possible with a second parallel 10S tower. From the 10S the list adds Megarevo MEGA0100TS.

Installation and location

Dimensions 591 × 390 × 1,569 mm, weight 492 kg – the floor must carry half a tonne; 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 (the heated version charges from −20 °C), fan cooling up to 55 dB.

Inverter compatibility

Besides those named, the 10S is marked with Solis S6-EH3P (12–20, 29.9–50 and 75–125 kW), Deye SUN-5K~25K, 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 G2 / G3, Solinteg MHT, Koyoe, ATESS, Sermatec, Sunways, Dunext, Livoltek, Megarevo, Sosen, TBB Power. Communication is CAN or RS485; we verify the inverter model from its label before you order.

Safety and warranty

Two parallel 10S towers are identical clusters linked through the BDU "Parallel" ports with CAN resistors and a DC busbar, with an age difference of up to 3 years. The warranty is 10 years in Europe with an active inverter connection (3 years without it), at least 70% of usable energy or 150.91 MWh of throughput; LiFePO4 cells, an extinguisher in every module, more than 8,000 cycles.
