Central to LONGi’s offering is its self developed 5S technology architecture, which integrates PCS, BMS, EMS, iCCS and TMS systems into a unified framework. The company said this enables greater operational control, improved efficiency and enhanced system reliability under varying operating conditions.
Safety remains a key focus for the company, which reported a track record of zero thermal runaway incidents across its deployments. LONGi is also advancing integrated solar plus storage solutions that combine intelligent digital platforms with lifecycle service capabilities aimed at improving long term asset performance.
Alongside its energy storage milestone, LONGi Solar also retained its Group level Gold Medal in the 2026 EcoVadis Corporate Social Responsibility ratings, achieving a score of 85.

According to EcoVadis analysts, LONGi demonstrated an advanced corporate social responsibility management system covering environmental performance, labour and human rights, business ethics and sustainable procurement.
EcoVadis is recognised as one of the world’s largest corporate sustainability ratings platforms. Its assessment framework is based on international standards including the United Nations Global Compact, International Labour Organization conventions, Global Reporting Initiative standards and ISO 26000 guidelines.
LONGi said sustainability remains central to its long term business strategy, supported by its corporate social responsibility and sustainable procurement management systems. The company added that it will continue integrating sustainable development principles into its global operations while strengthening partnerships that support the energy transition.
