Mastervolt Mass Combi 24/4000-100 120 V

Mass Combi 24/4000-100 (120 V)

The Mastervolt Combi literally combines’ an advanced battery
charger and silent-running inverter in one remarkably compact
device. But that isn’t all: it also adds extra functionality. This
includes Power Assist, system paralleling and secondary battery
charging. This makes the Combi your ideal solution for a wide range
of needs, from low power recreational use right up to full-on, high
power industrial applications.

Versatility in power supply

Every model of the Mastervolt Combi is highly versatile, so
using one greatly simplifies installation. This single product not
only brings you fast and complete charging of your starter and
service batteries, it also provides a silent, robust and clean AC
power supply. Multiple AC outputs allow heavy-draw items to be
separated from the most critical equipment, making sure they don’t
unintentionally deplete your batteries. The AC inputs facilitate
both mains and generator connections, which the Combi can support
with additional power if your loads require more than either can
provide. Essentially, just this one product can handle all the
power requirements in an autonomous system. 

Modern technology

The unique design of the Combi range is typically Mastervolt.
Rather than installing heavy transformers, you can use Mastervolt’s
high-frequency technology for major benefits in terms of compact
size, a lightweight chassis and silent running (there is no
transformer hum). 

Perfect in a MasterBus system

Designed for system compatibility, the Mastervolt Combi fits
perfectly into a MasterBus system. The network will allow you to
easily control and monitor your product, while also optimising the
configuration to your needs. In addition, the internal
communication between other MasterBus products in your system can
even boost the overall electrical performance.

Benefits of the Mass Combi

• Compact, lightweight and no hum thanks to HF technology.
• High yield and more power from your batteries.
• Intelligent 3-step+ battery charger with low DC ripple current
  for fast charging times and long battery life.
• Charges two individual battery banks simultaneously.
• Quiet, powerful inverter with 200 % peak power.
• Power Assist: extra power assistance from the batteries in case
  of limited grid or generator power (prevents blown fuses).
• Pure sine wave energy prevents failures and damage to sensitive
  equipment such as adapters.
• Dual AC outputs to separate critical equipment from heavy
  loads.
• Higher yields possible via parallel switching (only 2500 W
  models).
• Professional connections ensure fast installation and
  operational security.
• CE approved and E-marking for mobile applications.
