THE SELDERS SYSTEM
Battery: MLI Ultra 12/2500
The battery is the heart of the electrical system in this
motorhome. Given the space limitations, both the size
and capacity of the battery were highly relevant. This
is why the owner and installer opted for the highly
compact MLI Ultra 12/2500 Li-ion battery providing no
fewer than 180 amp-hours. Thanks to this mini power
station, the motorhome can spend a night in a place
without any mains connection – ideal for independent
and adventurous travel, with no prior arrangements
Mass Combi 12/1600-60
This battery charger and inverter in one has an inverter
capacity of up to 1600 watts. That means there is always
energy for heavy AC consumers, such as the TV and
Nespresso coffee machine.
Digital switching: Wireless Interface
The Wireless Interface and free downloadable app allow
the entire system to be monitored and operated via iPad.
The Wireless Interface provides for a wireless connection
between the iPad and the Mastervolt system, and can also
act as a client for the main router. This has the advantage
of letting users log onto one wireless network to use both
the internet and other applications.

The biggest daily AC consumers in the Mercedes include several LED groups
for lighting, a refrigerator, kitchen appliances, a smart screen and underfloor
heating. The design of the system also takes into account a number of ‘free’
consumers to be determined.
Monitoring and operation via a single display, in this case an iPad. The
tablet also provides readouts of data such as battery status and inverter
The capacity to create handy modes of operation: complete convenience
at the press of a button.
Long periods of independence from the grid.
Charging grid power without thinking: as soon as there is a mains
connection, the Combi links it directly to the AC consumers while also
charging the Lithium Ion battery in parallel.
