LONGi Unveils LONGi ONE, Ushering in a New Era of Integrated Solar-Plus-Storage Systems

BEIJING, April 2, 2026 /PRNewswire/ -- LONGi has officially unveiled its LONGi ONE integrated solar-plus-storage strategy, marking a transition from traditional multi-vendor architectures to a unified system design.

A Shift from Fragmentation to Integration

As solar energy establishes itself as a core pillar of the global energy system, conventional "assembled" solutions are increasingly constrained by efficiency losses, complex commissioning, and unclear accountability. LONGi ONE addresses these challenges through full-stack, self-developed native integration, combining advanced BC solar technology with 5S storage technology to deliver a unified, high-performance "Solar Generator."

One System, One Platform, One Responsibility

LONGi ONE is built upon three core principles: One System, One Platform, and One Responsibility.

Its natively integrated architecture reduces system losses, enhances performance, and shortens deployment timelines. The AI-driven platform enables coordinated optimization across generation, storage, and consumption.

Equally important, the One Responsibility principle redefines accountability in solar-storage systems. Instead of managing multiple vendors, customers work with a single partner—LONGi—across the entire lifecycle. This eliminates fragmented interfaces, avoids responsibility gaps, and ensures faster issue resolution with clear ownership.

A Comprehensive Product Portfolio

LONGi ONE delivers tailored solutions for two key market segments: utility-scale and commercial & industrial (C&I) applications.

For utility-scale projects, OneBank 2.0 offers a fully integrated AC/DC storage solution featuring advanced safety design. Its proprietary iCCS technology enables millisecond-scale fault detection and isolation, reducing system-level failure rates by 60% and cutting pre-commissioning time by over 30%.

OneMatrix 2.0 provides a flexible, modular approach for plant-level deployment, supporting multiple duration scenarios (2h/4h/8h) while reducing deployment time by 20-30% and lowering lifecycle costs.

For C&I users, Hi-MO One—paired with the EnergyOne platform—delivers 24.8% module efficiency and up to 90.3% system efficiency. With response times under 20 ms and AI-driven energy management, it enables intelligent operation and optimized returns.

Global Service Network Expansion

LONGi has also launched its "2830 Plan," which aims to establish 30 localized service centers across key global markets by 2028.

Supported by 13 GWh of delivery experience across over 120 countries, this network will provide end-to-end lifecycle services, ensuring rapid, localized support worldwide.

Toward the Solar Generator Era

From monocrystalline to BC technology, and from PV to storage, LONGi remains committed to translating innovation into customer value. With LONGi ONE, the company aims to redefine solar energy as a stable and intelligent "Solar Generator"—supporting the next phase of the global energy transition.
