Recently, LONGi has signed a 1GWh strategic cooperation agreement with Zhongtian Technology (ZTT). This marks a significant milestone in bringing its “LONGi ONE” strategy from concept to commercial deployment, and demonstrates market recognition of LONGi’s full-stack integrated energy solution.
On April 1, LONGi officially unveiled its “LONGi ONE” Solar-Plus-Storage integration strategy, which redefines the relationship between solar and storage from the ground up. By leveraging fully self-developed, natively integrated technologies, LONGi 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. The goal is to provide global customers with a unified, efficient, and safe green power solution, along with asset protection.
“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 launched a full-scenario product portfolio covering utility-scale, commercial and industrial applications. This includes OneBank 2.0 for GWh-scale power plants, OneMatrix 2.0 for flexible, plant-level requirements, and 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.”
Notably, 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, which no longer need to coordinate among multiple suppliers. With unified technical standards, after-sales system, and responsibility, issues can be clearly traced and quickly resolved. This puts an end to finger-pointing among different equipment manufacturers.
“LONGi ONE” is not just a technological upgrade; it represents a shift in Solar-Plus-Storage integration from “device assembling” to “intgrated system capability.” This transformation addresses current industry pain points and has already gained recognition from many customers.
As deployment and large-scale application accelerates, solar-storage integration solutions are poised to provide a more scalable, reliable and flexible pathway for the global energy transition.
