Description

The Dyness STACK100-11S is an eleven-module high-voltage (HV) LiFePO4 battery: 56.32 kWh nominal capacity, 53.50 kWh usable energy (95% DOD). It is the configuration for a hotel, a school or a cold store with a 45–55 kW solar plant, when the 10S is no longer enough but a 12S tower no longer fits the room. Indoor installation (IP20).

Capacity and power

Eleven modules operate in the 492–642 V range – from the 11S the lower edge of the window passes 490 V; of the Solis range only the 12 kW and larger models remain on the list. Recommended charge and discharge power is 28.16 kW (0.5C), with short peaks up to 56.32 kW (1C). The tower has room for one more module (up to 12 per column recommended); more capacity comes with a second parallel 11S tower.

Installation and location

Dimensions 591 × 390 × 1,702 mm, weight 539 kg. With the mandatory 200 mm gap above the tower, at least 1.9 m of free height is needed – the 11S still fits a 2.4 m room with a shelf or pipework above it, whereas with the 12S (1,836 mm) the margin is already smaller. The modules stack without cables and the tower is secured to the wall with the brackets supplied; operating temperature −20 to +50 °C (charging from 0 °C), fan cooling up to 55 dB. Leave 500 mm to other equipment and 30 mm to the wall.

Inverter compatibility

In the Dyness list (12/2025) the 11S is marked with Solis S6-EH3P(12-20)K-H, S6-EH3P(29.9-50)K-H and S6-EH3P(75~125)K10-NV-YD-H, 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 plus G2, BI G2, G3 and MP G3, Solinteg MHT, Koyoe, ATESS HPS, Sermatec, Sunways STH-4~12 KTL-HT-P, Dunext, Livoltek, Megarevo, Sosen and TBB Power. The Solis 3–10 kW models, Hoymiles, SAJ, Senergy and Sineng, marked with the 10S, are no longer here; Kostal PLENTICORE plus G2 and BI G2 are marked with the 11S for the last time. Communication is CAN or RS485; we check your inverter model against its label before you order.

Safety and warranty

Certifications that matter for a commercial site: IEC 62619, IEC 63056, IEC 62477, VDE 2510, CE-EMC / CE-RED, transport under UN38.3. Safety – LiFePO4 cells, an extinguisher in every module, a DC breaker in the BDU. The warranty is 10 years in Europe with an active inverter connection (3 years without it), at least 70% of usable energy or 166 MWh of throughput.
