Sungrow PowerTitan 3.0 ST6900UX-4H redefines utility-scale energy storage by combining advanced liquid cooling technology with the highest energy density. This New-Gen AC Block ESS maximizes performance while significantly reducing space requirements and installation costs.
Maximum Space Utilization & Rapid Deployment:
Thanks to the back-to-back design with a distance of just 15 cm, a 1 GWh ESS station requires only 6,951 m². With full factory pre-installation and pre-commissioning, on-site deployment takes only 12 days, while automatic configuration and self-checking of the entire station are completed in just 1 hour.
Maximum Performance Without Losses (Barrel Effects):
By using 1 independent PCS per battery rack, the system completely eliminates capacity limitations (“barrel effects”). Combined with multi-level SOC balancing (from cell to station level), the usable discharge energy is increased by 8%.
Smart Thermal Management with AI:
The AI Bionic Thermal Balance 2.0 technology applies a dynamic cooling strategy for each cabinet, ensuring precise temperature control within 1°C and reducing internal energy consumption by 19%. The exclusive rooftop air outlet ensures a 0°C temperature rise around the equipment, preventing the “thermal island” effect and providing an additional 9% energy saving.
Grid Stability (Grid-Forming) & Ultimate Safety:
It features the industry’s first full-spectrum Grid-Forming capability for Wind-PV-ESS systems, ensuring grid stability. Safety is enhanced by ArcDefender® 2.0 technology, which provides 100% accurate DC arc fault detection.
