LONGi has signed a 1GWh strategic cooperation agreement with Zhongtian Technology (ZTT), marking a significant milestone in bringing its “LONGi ONE” strategy from concept to commercial deployment and demonstrating market recognition of the company’s full-stack integrated energy solution.
LONGi officially unveiled its “LONGi ONE” Solar-Plus-Storage integration strategy at the beginning of April, redefining the relationship between solar and storage from the ground up. By leveraging fully self-developed, natively integrated technologies, the company aims to build a “Solar Generator” that sets global benchmarks for efficiency and safety, completely breaking down the silo effect between solar and storage systems.
LONGi ONE achieves native integration from high-efficiency BC technology to the patented 5S energy storage technologies (BMS, iCCS, EMS, TMS, PCS). Built on the three pillars of “One System, One Platform, One Responsibility,” the company has now launched a full-scenario product portfolio covering utility-scale and commercial and industrial applications. This includes OneBank 2.0 for GWh-scale power plants, OneMatrix 2.0 for flexible, plant-level requirements and the Hi-MO One + EnergyOne solution for commercial and industrial applications. Through system-level coordination, these solutions reduce conversion losses and enable a shift from “passive response” to “active decision-making.”
LONGi’s proprietary iCCS safety detection system, combined with a multi-dimensional thermal runaway warning model, enables millisecond-level fault isolation and eliminates thermal runaway risks.
As a result, from solar modules to energy storage systems, and from hardware delivery to lifecycle operation and maintenance, customers work through a single interface with LONGi, no longer needing to coordinate with multiple suppliers. With unified technical standards, after-sales system and responsibility, issues can be clearly traced and quickly resolved.
LONGi ONE is not just a technological upgrade; it represents a shift in Solar-Plus-Storage integration from “device assembling” to “integrated system capability.” This transformation addresses current industry pain points and has already gained recognition from customers.
