The majority of your RV lighting is powered by
12 VDC electricity. The 12 VDC system is
composed of components that will operate
when the following conditions are met:
Power is supplied by the tow vehicle
alternator when the engine is running and the
7-way trailer plug is connected. This powers
the RV's running lights, brake lights, turn
signals and brakes. In addition, the 7-way
trailer plug provides a common ground and a
12-volt charge line to charge the auxiliary
battery.
The converter will supply interior 12 VDC
power when the 50-amp power cord is
plugged
into
campground
converter will also charge the auxiliary battery
in most situations.
The auxiliary battery powers many interior
12-volt components including the lighting
fixtures, water pump, 12-volt motors, 12-volt
appliances, etc. It also powers the breakaway
switch.

You may want to have a solid-state battery
isolator installed on your tow vehicle starting
system as a convenience feature. It receives
current from the tow vehicle alternator and
controls distribution of energy to both the
auxiliary battery(s) and the tow vehicle
battery. It also serves as a check valve to
prevent energy from being drawn from your
tow vehicle chassis battery (so you can start
your tow vehicle engine).
Your dealer can assist you with the selection,

Your RV has many 12 VDC loads. When
combined, their total is more than the
converter can produce. High demands for
12-volt power can be met by an auxiliary
battery for limited periods of time. The 12
VDC electrical system is designed for usage
with a Group 24 or Group 27 deep cycle
batteries. To prevent damage, do not connect
an automotive style battery to your RV
electrical system.
A deep cycle battery is rated in amp/hours
(how many amps, for how long, you can draw
from your deep cycle battery before it is
discharged).
