CE+T Bravo Inverter Systems: Resilient 3-Port Modular AC Power
Bravo Inverter Systems represent a paradigm shift in AC power protection, specifically engineered for environments where even a millisecond of power interruption is unacceptable. Utilizing CE+T’s patented 3-port architecture, these systems maintain a permanent, synchronized connection between the AC grid, the DC battery bank, and the critical load. This unique configuration enables Enhanced Power Conversion (EPC), which provides total galvanic isolation and filters all grid disturbances while ensuring a true 0ms transfer time during a primary source failure. Unlike traditional inverter-static switch combinations, Bravo Inverter Systems eliminate the risks associated with mechanical switching, providing a continuous and “clean” AC sine wave that is vital for sensitive telecommunications equipment, industrial automation, and utility protection relays.
The modularity of Bravo Inverter Systems allows for a “pay-as-you-grow” approach, where capacity can be scaled from a single 1kVA/2.5kVA module to high-capacity redundant plants. With support for a wide range of DC input voltages—including 48Vdc for telecom and 110V/220Vdc for industrial substations—the platform offers unmatched architectural flexibility across diverse sectors. Management is centralized through the sophisticated Inview controller family, available in Gateway, Slot, and Standalone versions, offering deep site telemetry and remote management via web and SNMP. By combining hot-swappable hardware with high operational efficiency in EPC mode, Bravo Inverter Systems deliver a highly resilient and cost-effective infrastructure solution for the world’s most demanding critical power applications.
