Description

The Dyness STACK314-12S is a twelve-module high-voltage (HV) LiFePO4 battery in two columns: 192.96 kWh nominal capacity, 183.4 kWh usable energy (95% DOD). The almost 200 kWh capacity is tailored to companies with a 150–200 kW solar plant whose consumption falls outside the sunny hours – a bakery, dairy processing, a cold-storage warehouse, and sites limiting grid power during peak hours. It differs from the 11S by 16 kWh and by ATESS leaving the list.

Capacity and power

Twelve 16.08 kWh modules operate in the 537–700 V range (nominal voltage 614.4 V). The recommended 140 A current corresponds to 86 kW, the maximum continuous 200 A to 122.9 kW. With a 100 kW inverter the battery works with a margin, while for a 125 kW class inverter the power is limited by the battery (max. 122.9 kW) – for it choose the 13S or more. Expansion – three more modules (up to 15S) in the same two-column system.

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 stands in the main column, the modules stack without internal wiring. Two 770 × 425 mm footprints, total weight about 1,418 kg plus 18.5 kg; the floor load is checked at the design stage. Indoor installation (IP20); charging from 0 °C, discharging from −20 °C; because of fan cooling the room needs air exchange.

Inverter compatibility

In the Dyness list (06/2026) twelve modules are marked with 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. ATESS models end in the list at 11S. Growatt WIT 50–100K and Sinexcel PWS1-135M are marked only from 14S. Communication is CAN or RS485; we check your inverter model against its label before you order.

Safety and warranty

Twelve aerosol extinguishers (one per module) and a DC breaker in the controller; BMS with cell balancing, more than 8,000 cycles (0.2C, 25 °C), UN38.3 and IEC 62619. For charge calibration – a full charge at least every two weeks. Warranty – 10 years under the Dyness warranty terms; registration through the Dyness app.
