The motorhome living area electrical system is designed for
convenience. It is capable of supplying the vehicle with at least
two sources of power: 12 volt DC power and 110-120 volt AC
power.
The 12 volt auxiliary battery supplies power to the interior
components (except the roof air conditioner if equipped) for short-
term use. The 12 volt or DC, power supplies an AC 110-120 volt
current to the interior plug outlets through the 2000 watt true sine
wave inverter.
The auxiliary coach battery bank is charged when the chassis
engine is running and the red key disconnect switch is in the ON
position or when you are connected to a 110-120 volt power
source (shore power). Your vehicle may be equipped with solar
panels for charging the coach battery bank. These solar panels will
charge the auxiliary coach battery if the red key disconnect switch
is in the ON position.
For long term use, your vehicle may be powered by plugging into
a 110-120 volt external power source with the supplied 25 foot
power cable. The 25 foot power cable supplied with your coach
must be connected and locked to your coach and then to a 110 -
120 volt power source (a 30 amp power source is recommended).
This will supply 110-120 volt power throughout the interior and
charge the batteries to power all 12 volt components. Do not
run the air conditioner unless you are plugged into a minimum 20
amp power source. A surge protector is also recommended when
plugging in your coach.
Your motorhome is equipped with a pure-sine wave 2000 watt
Xantrex Freedom XC Inverter Charger. The charging portion of
the Freedom XC is set to LFP to charge the lithium ion phosphate
batteries. The Freedom XC also converts 110 volt into 12 volt to
charge the batteries for the 12 volt appliances when plugged into
110/120 volt power.
The pure-sine wave inverter takes the 12 volt or DC power from
your batteries and inverts it up to 110-120 volt AC power. The
inverter will enable you to use your 110-120 volt plug outlets
when a shore power source or generator source is unavailable.
This power source will be limited by the state of charge of your
batteries and by the amount of current drawn by each appliance.
The inverter has a built-in transfer switch that allows the 110-120
volt shore power to bypass the inverter and power the 110-120
volt plug outlets, when the motorhome is plugged into a shore
power source or running on a generator.

NOTE:
Connect and lock the power cord to your coach first and
then the external power source.
NOTE:
All dash components including the in-dash radio and
front map lights are powered through the Mercedes Sprinter
starting (chassis) battery. Prolonged use of these items when
the vehicle is not running will deplete the engine starting battery.
The engine starting battery is NOT charged through the coach
portion of the vehicle or through the solar panel system.
