IEB350kWh Standard BESS，IEB350kWh Construction Site Power Backup BESS
Standard BESS & Construction Site Power Backup BESS
Product Introduction
IEB350kWh standard battery energy storage system is specially designed for commercial and industrial applications. Featuring a fully liquid-cooled, all in one design, it achieves electrical isolation between input and output, significantly improving safety performance. The system is equipped with two 175kWh battery packs and supports 1P high power charging/discharging, making it highly efficient in heavy-load electricity usage scenarios. It supports PV access, helping businesses reduce electricity costs.
IEB350kWh construction site power backup BESS focuses on areas with no or weak power grids. It offers plug and play convenience. With rapid automatic on-grid and off-grid function, it enables seamless switching between power supply modes. Supporting lower power charging and high power discharging, it delivers stable power for critical loads. This makes it ideal for high-demand scenarios such as construction sites and oilfields, ensuring uninterrupted power supply even during emergencies or in hash environments.
