LONGi Enters European Storage Market with Integrated ONE System
At Intersolar Europe 2026, LONGi Energy Storage launched its LONGi ONE architecture, a fully integrated solar-plus-storage solution. By bundling photovoltaic generation, battery storage, and energy management into a single platform, the company aims to position itself as a critical infrastructure provider within the increasingly complex European power grid.

The debut highlights a shift in market priorities, as project developers move away from standalone assets toward unified systems capable of ensuring grid stability. The system incorporates multi-layer protection and intelligent monitoring, focusing on early risk identification to maintain safety standards throughout the asset's operational life. To support these deployments, the company also unveiled OneNexus, an extension of the portfolio tailored for microgrids and distributed energy scenarios where generation and load must operate in tight coordination.
Beyond hardware, the company is doubling down on regional service infrastructure to meet stringent European regulatory requirements. Supported by a global network, LONGi reports an average mean time between failures of 8,500 hours for its existing European installations. With a goal of establishing 30 local service hubs by 2028 under its '2830 Plan', the firm is promising sub-48-hour issue resolution to maintain long-term performance for its regional clients.
