Standalone Pure Sine Wave DC-AC/AC Inverter With No Single Point of Failure

Low power requirements usually mean the installation of a standalone inverter together with a Manual ByPass.The main inconvenient is of course that in case of inverter failure, your load is down during the time it takes to access the site and engage the By-Pass!

Hot-swappable Inverter with automatic by-pass

  •  Hot-swappable inverter module requiring only seconds to be replaced
  • Automatic by-pass engagement in case of inverter failure
  • TSI CE+T BRAVO INVERTERSwitching back to inverter automatically when the
    system is ready

BRAVO – ST is a compact inverter with automated by-pass solution providing a pure sine wave AC supply. In conjunction with a DC Power system, it provides an excellent AC backup solution. It uses the latest inverter technology, providing superior energy efficiency in a compact size.

The “Twin Sine Inverter” (TSI) technology allow 3 operations mode (EPC double conversion AC to AC, ONLINE DC to AC from battery and o line by-pass to AC). The automatic bypass to AC allow easy hot plug module replacement without stopping the load giving highest AC output availability and avoid the need of an external manual by-pass.


All business critical applications and all types of AC loads. The solution is designed for highest AC output availability. Both inverter modules and by-pass are hot-swappable which ensures low Mean Time to Repair (MTTR), reduction in service costs.
