PVTIME – PV giant LONGi has signed a strategic cooperation agreement with Zhongtian Technology Group (ZTT) for a 1GWh energy storage project. This marks a key milestone in the commercial rollout of LONGi’s full-stack PV-storage integration strategy, LONGi ONE, and reflects strong market validation.
Launched on 1 April, LONGi ONE redefines PV-storage integration by offering fully in-house native integration technologies. This creates a global benchmark for efficiency and safety, known as the Solar Generator. Eliminating system silos, it delivers unified, high-performance green energy solutions and asset guarantees for clients worldwide, integrating high-efficiency BC photovoltaic technology with the full 5S energy storage system (BMS, iCCS, EMS, TMS and PCS).
Built on the principles of ‘One System’, ‘One Platform’ and ‘One Responsibility’, the solution offers a comprehensive product portfolio for various scenarios: One Bank 2.0 for GWh-level power stations, One Matrix 2.0 for utility-scale flexibility, and Hi-MO One+Energy One for industrial and commercial sites. System-level synergy reduces cumulative losses and shifts operations from passive response to proactive decision-making.
LONGi’s proprietary iCCS safety system and multi-dimensional thermal runaway warning model enable millisecond-level fault isolation and fundamental thermal runaway control. Under LONGi ONE, customers receive end-to-end support for generation, storage and consumption via a single point of contact. Unified standards, service and accountability ensure issues are resolved quickly, putting an end to disputes over supplier responsibility.
LONGi ONE is more than just a technological upgrade; it marks the industry’s shift from equipment assembly to integrated system capability, solving key pain points and winning client recognition. As full-stack deployment accelerates, PV-storage integration will provide a more stable technological basis and scalable solutions for the global energy transition.
