Product Overview
The CE+T Bravo25 T621330201 is premium dual-input modular pure sine inverter designed for North American standard 120Vac power applications, converting 48VDC battery into stable 120V alternating current with rated 2.75kVA/2.25kW output. Equipped with independent auxiliary AC input to lift overall conversion efficiency, it automatically shifts from mains to battery power instantly during grid blackout without load interruption. Multiple units can be paralleled flexibly to build single-phase, two-phase(2×120V+N) or three-phase(3×208V+N) power system, scalable from standalone 2.75kVA up to max 88kVA large uninterrupted power station. Low ripple output avoids battery and DC equipment disturbance, widely deployed in telecom, data center, transit, industrial and renewable energy backup projects.
Key Features
