Description

The Dyness STACK314-13S is a thirteen-module high-voltage (HV) LiFePO4 battery in two columns: 209.04 kWh nominal capacity, 198.6 kWh usable energy (95% DOD). This is the limit up to which the system can still be connected to 30–50 kW class Deye, Solis, Hiconics and Sosen inverters – the 13S is the last configuration in their rows of the Dyness list. The variant therefore suits cases where the largest capacity is needed with an existing medium-power hybrid inverter: for long night consumption or two days without sun.

Capacity and power

Thirteen 16.08 kWh modules operate in the 582–759 V range (nominal voltage 665.6 V). The recommended 140 A current corresponds to 93.2 kW, the maximum continuous 200 A to 133.1 kW. With a 50 kW inverter the battery works at barely 0.25C, which is gentle on the cells; with 125 kW class Solis or Solinteg, between the recommended (93.2 kW) and the maximum continuous (133.1 kW) power. Expansion – two more modules (up to 15S).

Installation and location

The expansion kit is included: a second base (133 mm), a cover (80 mm), 50 mm² cables linking the columns and a communication cable. The SBDU200 controller is in the main column, the modules stack without wiring, and the columns are secured with wall brackets. Two 770 × 425 mm footprints, total weight about 1,533 kg plus 18.5 kg – the floor load is calculated at the design stage. Indoor installation (IP20), charging from 0 °C, discharging from −20 °C.

Inverter compatibility

In the Dyness list (06/2026) thirteen modules are marked with Deye SUN-29.9–50K-SG01HP3-EU-BM3/4 (13S is the last) and SUN-60–80K-SG02HP3-EU-EM6, Growatt WIT 29.9–50K-XHU, Hiconics MH-HYIV29.9/30.0-TH, Megarevo MEGA0100TS, Solinteg MHT-25–50K-100, M2HT-25–50K-150 and M2HT-75–125kW-300, Solis S6-EH3P(12–20)K-H, (29.9–50)K-H and (75–125)K10-NV-YD-H, Sosen SSE-HH30-60K-P3 and SRNE IESP 50–60kW. If you plan 14 or 15 modules, Hiconics, Sosen, Solis 12–50 kW and Deye SG01HP3 are no longer suitable. Communication is CAN or RS485; we check your inverter model against its label before you order.

Safety and warranty

Thirteen aerosol extinguishers (one per module), a DC breaker in the controller, BMS with cell balancing; more than 8,000 cycles (0.2C, 25 °C), UN38.3 and IEC 62619. Warranty – 10 years under the Dyness warranty terms; registration through the Dyness app, and the state of charge is also shown by the controller's LED indicator.
