THE SELDERS SYSTEM

System choice

n

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

necessary.

n

Inverter/charger combination:

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.

n

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.

Energy consumption

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.

The basics

n

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

capacity.

n

The capacity to create handy modes of operation: complete convenience

at the press of a button.

n

Long periods of independence from the grid.

n

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.
