12 Volt System
State of Charge (SOC) is the primary concern when
using only battery power (boondocking) from the
onboard battery pack� SOC is displayed in percentages
on the home screen and electrical screen of the
Multiplex panel�
Everything except the A/C, hot water electric element,
outlets, cooktop, and microwave runs on 12 volt power
(note: some of these appliances have 12 volt electronic
boards and require 12 volt power to operate)�
Power is routed from the house battery to the 12 volt
distribution panel and through its branch circuits to the
rest of the touring coach� All 12 volt current is routed to
a 12 volt fuse block� Power from the fuse block goes to
a busbar holding Type 2 thermal breakers� The thermal
breakers feed electrical components throughout the
touring coach�
CAUTION
Thermal breakers break contact when overheated
by a short or overload in the wiring. These
breakers automatically reset when cooled down.
A breaker continually overheating and breaking
contact should be investigated by a qualified
service technician.
NOTE
The engine battery and house battery are isolated
from each other, preventing the two systems from
drawing down simultaneously.
Solar System
The rooftop solar panel installed on your Airstream
helps maintain battery charge of both the house and
chassis batteries� The solar system's solar charge
controller gathers energy from the solar panel and
stores it in your batteries�
To optimize solar charging, ensure the panel is clean
and not shaded by trees or structures that might
block the sun� Please refer to your owner's packet for
reference material that discusses the solar system and
its operation�

Electrical System Operation
Your touring coach has a powerful 270Ah 12V LiFePO4
(Lithium Iron Phosphate) Deep Cycle House Battery,
a 100 Amp Charger, a 2,000 Watt True Sine Inverter
and vehicle alternator� These components work in
conjunction to provide a seamless experience whether
hooked up to shore power, boondocking on battery
power, or driving to the destination�
The information in this manual touches on the
highlights of the system, its components, essential
functions, and operation� Before operating the system
review the Inverter/Charger and Battery information
in your Owner's Packet for important warnings/limits,
operating instructions, and tips for using the battery�

Battery Disconnect Switch
The battery disconnect switch is behind the left rear
door and must be on to charge the battery and/or
operate the various electrical systems in the coach�
Rotate the knob to the right and left to turn the power to
your coach on and off�
Do not over rotate the battery disconnect switch.
Over rotating can damage the switch rendering it
inoperable, resulting in power loss.
