Bravo 10 is a compact modular inverter that converts a 48 Vdc power source into 230 Vac. By using at least three modules, we can offer solutions for three-phase infrastructures (3x400Vac + N).An additional AC input is used under normal conditions to achieve an overall conversion efficiency of 96%. In the event of a grid failure, it automatically switches to the DC to secure the loads.
The modularity is maximum thanks to increments of 1.25 kVA / 1 kW only! Different configurations are possible such as monitoring integrated in the shelf or not, and for single-phase or three-phase systems.
From 1 to 32 modules, with several options available (manual external by-pass and AC distribution), the Bravo ECI is also hot-swappable meaning very easy and cheap maintenance. The modules are delivered with our new monitoring solution.
