Overview
- Sungrow unveiled PowerTitan 3.0 and a single‑platform DC‑coupled solar‑plus‑storage system at its PV & ESS Summit in Sydney, positioning both as ready for utility‑scale use.
- PowerTitan 3.0 uses a containerized AC block that packs a 1.78 MW power conversion system and 7.14 MWh of batteries in a 20‑foot unit, scaling to 7.2 MW and 28.5 MWh per block in a four‑hour setup.
- The company cites 99.3% peak efficiency for the power electronics, an around 92% round‑trip efficiency at the system level, and a rapid‑build process it says can deploy 1 GWh of storage in 12 days.
- The new hybrid design connects batteries on the DC side to cut conversion steps and AC hardware, and Sungrow says independent testing found a 3–5% gain in total system efficiency with up to eight hours of discharge.
- Targeting Australia’s grid needs, Sungrow highlights grid‑forming controls for voltage and frequency support and black start, while in South Africa it showcased C&I and utility solutions and released a storage safety white paper with TÜV Rheinland.
