What is the
Mastervolt Mass Combis are
equipped with an extremely
advanced system to prevent the
AC power fuse from becoming
overloaded. The output current
of the battery charger is reduced
as soon as there is a risk of this
happening. If this proves insufficient,
the system rapidly switches to
inverter operation so that the
battery temporarily powers a part
of the connected load. Since the
inverter will already have been
synchronised and the switching is
so fast, computers will continue
functioning, as will clocks and
timers on, for instance, microwave
ovens. Once the load decreases,
the system switches back to power
and the battery charger returns to
charging the batteries. Your Combi
can therefore also function as an
efficient emergency power system.
The electrical system is connected to the grid. The circuit breaker is limited to 6 amps.
Several 230 V appliances are switched on, consuming 3.5 kW. A total of 16 amps is
required. The additional 230 V (10 A) is supplied via the service battery and the Mass
Combi. Automatic switching off prevents excessive discharge of the batteries. You
can program the setting via Power Sharing in the Mass Combi, or remotely using the
EasyView 5 panel.
In this case your power sources are a generator and the grid connection. Both sources
can charge the batteries and provide power to the connected consumers. The Mass
Combi Ultra regulates supply and demand and can optionally even start the generator
through MasterBus. In case of large power demand, the Mass Combi Ultra provides
additional AC power from the Lithium Ion battery, in parallel with either the generator
or the grid connection. This way you can operate larger loads without overloading the
generator or blowing the main fuse.
Example 1 - Mass Combi
Higher consumption than available from the grid.
Example 2 - Mass Combi Ultra
No grid - only generator and battery power.
