Description

The Dyness STACK314-11S is an eleven-module high-voltage (HV) LiFePO4 battery in two columns: 176.88 kWh nominal capacity, 168.1 kWh usable energy (95% DOD). The variant is meant for companies with a 100–150 kW plant and two shifts: in the morning the battery covers the start-up peak, during the day it stores the surplus, in the evening it feeds refrigeration and ventilation. Compared with the 10S, it is not just 16 kWh more – the voltage passes 490 V and the inverter list starts to shorten.

Capacity and power

Eleven 16.08 kWh modules operate in the 492–642 V range (nominal voltage 563.2 V). The recommended 140 A current corresponds to 78.9 kW, the maximum continuous 200 A to 112.6 kW. The battery serves a 100 kW inverter at full power with a margin (max. 112.6 kW), while for 125 kW class inverters the 13S or 14S suits better. Expansion – four more modules into the same two columns (up to 15S, 241.2 kWh).

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 internal wiring, and both columns are secured with wall brackets. Two 770 × 425 mm footprints, total weight about 1,303 kg plus 18.5 kg – a concrete floor and 450 mm of clearance above the taller column are required. Indoor installation (IP20), charging from 0 °C, discharging from −20 °C.

Inverter compatibility

In the Dyness list (06/2026) eleven modules are marked with ATESS HPS30000/40000/50000TL (11S is the last), Deye SUN-29.9–50K-SG01HP3-EU-BM3/4 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. Solis S6-EH3P(3–10)K-H and the ATESS HPS 30–150 series are no longer in the list from 11S. Communication is CAN or RS485; we check your inverter model against its label before you order.

Safety and warranty

Eleven 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. Expansion with modules – within 3 years of commissioning. Warranty – 10 years under the Dyness warranty terms; registration through the Dyness app.
