Mass Systemswitch 16 kW (230 V)

Mass Systemswitch: The complete system solution

  • Three AC inputs, for example inverter, grid power and generator.
  • Three or four outlets to AC power groups.
  • Automatic switching.
  • Power transfer from 4.5 kW to 16 kW, input/output from 25 to 63 A.
  • Information source for central energy management via MasterBus network.
  • Optional automatic fuses; for larger systems this usually requires an extra casing.
  • MasterBus compatible.

Suitable for MasterBus

As the Mass Systemswitch is suitable for MasterBus, all the information can also be read out on, for instance, a MasterView display, including the status of the charge current and the inverter.

LED indications on Systemswitch

Read out of the basic functions on the display, including indication of available power source, generator, grid power or inverter and ‘load on inverter’ function.

Central energy management

The MasterView Easy indicates AC current, amperage and frequency including the ‘load on inverter’ mode. The 12/24 V read out shows current, power (charge/discharge) and battery monitoring, and has a start/stop generator.

Smart electronics

The intelligent electronics control the switching to ensure that the equipment does not use too much power. Its double pole relay is sustainable and incredibly safe.
