3.4.1 Inverting mode
See figure 3-3. When there is no external AC power
available, the inverter of the Mass Combi Ultra provides AC
power on the AC outputs.
Figure 3-3: Inverting mode
3.4.2 Charging mode
See figure 3-4 and 3-5. When external AC power comes
available on the Mains- or Gen input, the main battery will
be charged and the AC outputs are supplied by the
external power.

Figure 3-5: AC power from Mains input
3.4.3 Output 1 and 2
See figure 3-6. The Mass Combi ultra has two AC-outputs.
AC-power is always available on output 1 and this is the
ideal output for loads that need continuous AC-power.
Output 2 is only available when external AC power comes
available on the Mains- and/or Gen input. Output 2 policy is
configurable by the dipswitches locally on the Mass Combi
Ultra or a MasterBus monitoring device. (See chapter
4.3.2).
