- LONGi introduces unified solar and storage platform to replace multi-vendor systems.
- New solutions target utility scale and commercial and industrial segments with efficiency gains of up to 90.3%.
- Global service expansion plan to establish 30 centres by 2028.
LONGi has unveiled its LONGi ONE integrated solar and storage strategy, signalling a shift away from fragmented project architectures toward a fully unified system design.
Announced in Beijing on April 1, the strategy combines the company’s back contact solar technology with its 5S storage platform into a single integrated solution described as a Solar Generator. The move reflects growing demand for simplified, high performance energy systems as solar power becomes a central pillar of the global energy mix.
The company said traditional multi-vendor systems are increasingly constrained by efficiency losses, complex commissioning processes and unclear accountability. LONGi ONE aims to address these challenges through a fully integrated architecture designed to reduce system losses, improve performance and shorten deployment timelines.

At the core of the strategy is a framework built on three principles described as One System, One Platform and One Responsibility. The unified platform uses artificial intelligence to optimise energy generation, storage and consumption, while positioning LONGi as the single point of accountability across the entire project lifecycle.
According to the company, this approach eliminates fragmented interfaces between suppliers and enables faster issue resolution through clear ownership.
The LONGi ONE portfolio includes solutions tailored for both utility scale and commercial and industrial applications.
For utility scale projects, the company has introduced OneBank 2.0, an integrated AC and DC storage system incorporating advanced safety features. Its proprietary iCCS technology enables millisecond level fault detection and isolation, reducing system level failure rates by 60% and cutting pre commissioning time by more than 30%.
LONGi also launched OneMatrix 2.0, a modular plant level solution designed for flexible deployment across two hour, four hour and eight hour storage durations. The system is expected to reduce deployment time by 20% to 30% while lowering lifecycle costs.
In the commercial and industrial segment, the Hi MO One solution, paired with the EnergyOne platform, delivers module efficiency of 24.8% and system efficiency of up to 90.3%. The system features response times below 20 milliseconds and incorporates artificial intelligence driven energy management to optimise operational performance and returns.
Alongside the product rollout, LONGi announced its 2830 Plan, a global service initiative aimed at establishing 30 localised service centres in key markets by 2028. The company said the plan builds on more than 13 GWh of delivery experience across over 120 countries and will provide end to end lifecycle support.
The launch also marks LONGi’s first comprehensive energy storage strategy following its acquisition of Potis Edge, signalling a broader transition from photovoltaic manufacturing toward integrated energy solutions.
With LONGi ONE, the company aims to position solar power as a stable, dispatchable and intelligent energy source, supporting the next phase of the global energy transition.
