HQESS Ships 3.3 MW Indoor Battery Storage System to Overseas Market

Delivery overview

HQESS has completed factory acceptance and dispatched a 3.3 MW / 3-hour indoor battery storage system for an overseas project, with the final units consolidated for shipment to the project site.

Overseas storage markets set high bars on safety, stability and grid compatibility. This project was engineered against those requirements from the start.

What was delivered

• A 3.3 MW / 3-hour high-safety indoor storage system
• 16 battery cabinets, organised into 8 clusters
• 1,375 kW single-unit PCS — among the highest single-unit capacities in its class among deployed overseas storage systems

Safety engineering

The system uses high-safety lithium iron phosphate (LFP) cells, together with a new full-system insulation material that substantially raises high-temperature and arc-resistance performance. The combination is designed to meet strict overseas fire-safety requirements, adding a second layer of protection beyond standard practice.

Performance engineering

The 1,375 kW PCS raises both operating efficiency and grid compatibility — the result of sustained R&D investment in high-end storage hardware.

Factory acceptance before shipment

On 19 March, a full factory acceptance review was completed with the project party and HQESS’s delivery partner. A combined technical team verified the complete system item by item, and every indicator met overseas market requirements before the equipment cleared acceptance.

The units were packed and consolidated in early June and are being shipped to the overseas project site.

What it represents

For HQESS, this is a milestone in commercial deployment outside its home market — and a step from product export toward technology, standards and brand export. The company continues to focus on storage R&D and quality, building safer, more efficient systems for overseas high-end markets.

交付概况

HQESS 已完成一套 3.3 MW / 3 小时室内电池储能系统的出厂验收，并将最终设备集结发往海外项目现场。

海外储能市场对安全性、稳定性和电网友好性有较高要求。本项目从设计之初便围绕这些要求展开。

交付内容

• 3.3 MW / 3 小时高安全室内储能系统
• 16 台电池柜，组成 8 个电池簇
• 1,375 kW 单机 PCS，在已部署的海外储能系统同类设备中具备较高的单机容量

安全设计

系统采用高安全磷酸铁锂（LFP）电芯，并结合全新的系统级绝缘材料，提升耐高温与抗电弧性能。该组合面向严格的海外消防安全要求，在常规防护基础上增加第二层保障。

性能设计

1,375 kW PCS 同时提升运行效率和电网友好性，体现了 HQESS 在高端储能硬件上的持续研发投入。

发运前出厂验收

3 月 19 日，项目方与 HQESS 交付合作伙伴共同完成出厂验收。联合技术团队逐项核验完整系统，所有指标在设备通过验收前均满足海外市场要求。

设备于 6 月初完成包装与集结，并发往海外项目现场。

项目意义

对 HQESS 而言，这是产品在海外市场实现商业化部署的重要节点，也标志着企业从产品出口进一步走向技术、标准与品牌输出。公司将继续专注储能研发与质量，为海外高端市场打造更安全、更高效的系统。
