PowerTitan 2.0 ST5015UX-2H

Sungrow's PowerTitan 2.0 integrates a 2520 kW string PCS and 5015 kWh of LFP batteries into a single 20 ft container that outputs AC power directly. The ST5015UX-2H is the two-hour variant, built on 3.2 V / 314 Ah cells in a 416S12P arrangement running between 1123.2 V and 1497.6 V DC, with a transformerless 690 V AC connection, an IP55 enclosure and a -30 to 50 °C operating range that derates above 45 °C. Sungrow presents the unit as pre-assembled and function-tested in the factory, with the electrical and battery cabinets kept separate to prevent thermal runaway, intelligent liquid cooling with automatic coolant refilling, and ArcDefender arc detection stated at a 100% detection rate and shutdown within 0.2 seconds. Cluster control lets each battery rack charge and discharge independently, which the manufacturer credits with an 8% gain in discharge capacity, while the single-sided door and back-to-back layout are claimed to cut footprint by 10-30% against traditional ESS.
