PowerTitan 3.0 ST6900UX-4H — 20-ft BESS container, 6.9 MWh, with SiC PCS

PowerTitan 3.0 is a 20-ft BESS container holding 6,904 kWh of LFP cells with built-in silicon carbide (SiC) converters. AC power is 4 × 450 kVA at 690 V with THDi below 1%, so current harmonics put almost no stress on the substation transformer. It comes in DC and AC versions for grid and generation projects.

Description

The container ships pre-installed and already commissioned, so on site it goes onto the foundation and gets connected. Its converters support virtual inertia and grid voltage regulation, which helps a weak grid hold frequency and voltage. The design is transformerless with a 690 V output, so an external step-up transformer is needed to reach medium voltage. DC voltage is 1,101.6–1,489.2 V. Cooling is liquid, operating temperature −30 to +45 °C, and the enclosure is IP55 with C4 corrosion resistance. It measures 6,058 × 2,896 × 2,438 mm and weighs 55 t, which calls for a heavy tractor unit and a crane. The system complies with UL 9540A, IEC 62619, IEC 62933-5-2, IEC 62477-1 and IEC 62443-4-2, the last one covering control system cybersecurity.

How to choose

PowerTitan 3.0 is the pick when one site needs a lot of energy in the fewest containers. At 6,904 kWh it is denser than the PowerTitan 2.0 ST5015UX at 5,015 kWh in the same 6,058 × 2,896 × 2,438 mm footprint. If the project is built on a central PCS with a 4,000 kVA transformer, the ST2236UX battery container at 2,236 kWh paired with an SC4000UD-MV fits better. Commercial sites at 125 kW are served by the PowerStack 255CS cabinet.

FAQ

What is the capacity of the PowerTitan 3.0 ST6900UX-4H?

6,904 kWh in a single 20-ft container.

What is the AC power of the ST6900UX-4H?

4 × 450 kVA at 690 V, transformerless.

How much does the PowerTitan 3.0 container weigh?

55 t at 6,058 × 2,896 × 2,438 mm.

Does the ST6900UX-4H need a transformer for grid connection?

The converters are transformerless with a 690 V output, so a medium-voltage connection needs an external step-up transformer.

What temperature range does PowerTitan 3.0 operate in?

−30 to +45 °C with liquid cooling, in an IP55 enclosure with C4 corrosion resistance.
