Designed for flexible deployment with IP67-rated battery modules and an IP54-rated cabinet, Guardian Indoor offers scalable performance, thermal stability, and unmatched safety.
Patented Immersion Technology
Battery cells are submerged in non-toxic dielectric oil for direct active thermal management, fire suppression, and propagation prevention.
Efficient Thermal Management
Submerging battery cells in our dielectric liquid prevents hot spots and allows the cells to consistently run at optimal temperatures.
Integrated BMS & EMS
Our non-Chinese BMS and EMS ensure optimal performance, safety, and efficiency, offering unmatched reliability and control.
Enhanced Fire Suppression
Our immersion fluid immediately cools and extinguishes any flames, ensuring enhanced safety and propagation prevention.
