4.8 MW Modular Inverter: Compact Design, High Performance
Sungrow’s new SG4800UD-MV-US modular inverter offers 4.8 MW capacity with 800 kW per unit, merging benefits of central and string inverters. Its modular architecture cuts balance-of-system expenses and allows inverter swaps in less than an hour, boosting uptime. Intelligent diagnostics and self-cleaning air filters simplify maintenance, while a unified spare part type streamlines operations. Rated NEMA 4X, it sustains full power output at temperatures up to 45°C (113°F). Advanced safety mechanisms include smart DC terminal monitoring and bottom pressure relief. With grid-forming and off-grid functionality, it supports earlier energy sales and improved project returns.

PowerTitan 3.0: Scalable AC-Coupled Storage
Designed for grid resilience and renewable integration, the PowerTitan 3.0 is an AC Block energy storage solution providing 6.9 MWh per 20-foot container. It incorporates high-capacity 661Ah LFP cells with a 12,500-cycle lifespan and a 430 kVA SiC-based power conversion system that reaches 99.3% efficiency. Five-level SOC balancing improves usable energy, and a compact layout reduces space use by 21%. The system includes multi-layer protection and ArcDefender™ safety technology, complies with North American regulations, and is pre-certified to UL9540. Its built-in grid-forming capabilities enhance grid recovery and support critical applications like data centers.

PowerStack 255CS: Versatile C&I Storage
The PowerStack 255CS all-in-one energy storage system serves commercial and industrial users with 257 kWh capacity. It features an integrated PCS and BMS, simplifying installation and supporting parallel expansion up to 6.4 MWh. With 98.6% PCS efficiency and 90% round-trip efficiency, the system uses liquid cooling to reduce auxiliary consumption by 40%. It meets UL9540, NFPA855, and other safety standards through rigorous testing. Suitable for solar pairing, EV charging, microgrids, and off-grid use, it offers flexibility for diverse energy needs.
