Modular Inverter Systems

Bravo inverters provide users with a highly efficient and modular AC or DC power solution that is fully scalable and uses hot-swap inverter modules at 2.5kVA 120VAC or 3kVA 230VAC.

The Bravo ECI and TSI models are compact 2U (3.5-in. high) rackmount inverters that can be configured with up to four 2.5kVA modules totaling 10kVA in a single 2U shelf. Units can be connected in parallel to increase the overall output of the inverter system and the hot-swappable modules can also be configured with N+1 redundancy. Moreover, the models provide extra AC input to ensure a high overall efficiency that results in a reduction of energy loss and heat dissipation.

Both inverter models convert 48VDC into a pure sine wave with an output of 120 or 230VAC. Outputs can be configured to deliver single, dual or three-phase AC power. The Bravo ECI technology eliminates all single points of failure with full scalability up to 32 modules in parallel and high efficiency of up to 96% in AC/AC conversion and above 93.5% in DC/AC conversion to minimize operating costs. Multiple Bravo ECI systems can be paralleled to reach up to 96kVA.

The Bravo TSI models can scale from 2.5 up to 80kVA with a minimum of three rack shelves required for three-phase operation. Designed for easy configuration, the modules mount four at a time into a 19-in. rackmount power shelf along with a management module. Multiple shelves can be connected in parallel and can be wired for single-phase or 3-phase operation.

For enhanced system communications, UNIPOWER offers an industry-first “translator” interface PCB that allows the inverters to seamlessly communicate with the existing UNIPOWER ACX controller through the PowCom network software. PowCom allows system communication through a local or remote PC and will automatically adjust its interface to the capabilities of the connected system—eliminating the need for two separate protocols.
