Mass Combi Ultra
Unparalleled performance
The Mass Combi Ultra 24/3500-100
can provide continuous 3,500W
inverter power at 40°C, and offers a
peak power of 200%. Moreover, the
Mass Combi Ultra comes with the
most powerful battery charger in its
class; with an unmatched 100A at full
charge voltage for the fast charging
of the main battery.
Separate second charger
All Mass Combi Ultras have an
integrated second charger which
(in most cases) can charge both 12V
and 24V batteries; a practical
function that simplifies installation
and reduces costs for the end-user.
Optimal battery usage
Based on Mastervolt’s many years of
experience, the Mass Combi Ultra
features a number of characteristics
that ensure you get the most from
your batteries in terms of maximum
power and lifespan. Key examples
include the pure, interference-free
DC voltage that prevents unnecessary
heating of the batteries and a low ‘no
load’ current that guarantees every
Ah is deployed in an optimal way.
Home comforts
The Mass Combi Ultra features
separate AC outputs. One is
permanently powered to supply
critical loads such as refrigerators
and audio systems. The other output
is for non-preferential loads including
water heaters that can be switched
off automatically at any desired
setting, always to the benefit of the
critical loads.
Ease of installation
The carefully designed connections
were optimised for installers.
Installation and connection have
been made quick and easy via a
logic layout, solid terminals and by
removing the need for cable glands.
Higher yield from solar power
On the DC side the Mass Combi Ultra
has interesting features such as the
solar input and the independent
second charger output. Mastervolt
has leveraged on the knowledge
gained in the grid-connected solar
sector to make a super-efficient
built-in MPPT solar charge regulator.
Compared to most regulators on the
market, the MPPT offers a far higher
yield from solar power for charging
your batteries.
Two AC inputs
The Mass Combi Ultra has two
separate AC inputs for generator or
mains supply, both adjusted to the
specific characteristics of each
power source. Thanks to the ultra-fast
controls, transfer to and from the
inverter is seamless, preventing any
flickering in the lights or the
unintentional powering down of
sensitive devices.
Parallel and 3-phase operation
The Mass Combi Ultra functionality
goes beyond stand-alone operation;
the design allows parallel and
3-phase operation for larger
applications up to 35 kW.
Quiet operation
The Mass Combi Ultra provides a high yield that, combined
with the Active Optima Cooling concept, ensures minimal use
of the fan. The advanced thermal design offers an optimal
performance when needed, and quiet operation when
required. The Combi can provide up to 50% of the charging
current or inverter capacity without fan cooling. This is perfect
for night-time operation; when little power is consumed, the fan
stops turning for silent operation. For maximum capacity
requirements or when the ambient temperature is very high,
the Active Optima Cooling concept regulates the fan speed in
a linear way. This ensures that it never spins too fast or makes
an irritating ticking noise.
