12 volt System
Your touring coach has a powerful 12,000 watt-hour
(12 kilowatt-hour) lithium-ion 58 volt battery pack (Flex
Pack)� State-of-Charge (SOC) is the primary concern
when using only battery power (boondocking) from the
onboard battery pack� To learn how to monitor SOC,
see Electrical System Operation on page 5-11
Home Screen on page 5-13�
With the Volta System on, dual 30 amp converters will
convert the battery's voltage from 58 volt direct current
(DC) to 12 volt DC to power 12 volt devices�
The majority of electrical power in your Airstream is
12 volt: lights, awning, electronics, shades, and more;
everything except the roof A/C, hydronic heating
and hot water electric element, outlets/receptacles,
cooktop, and microwave oven (note: some of these
appliances have 12 volt electronic boards and require
12 volt power to operate)�
Power is routed from the Volta Power System 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 panels installed on your Airstream
help maintain battery charge� The solar system's solar
charge controller gathers energy from the individual
solar panels and stores it in your battery� Under full
sun, solar watts may be depicted on the Volta System
and
see
display as Power Flow�
To optimize solar charging, ensure the panels are
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�
The solar panels will not provide any charge to the
batteries if the Battery Power (battery disconnect)
pushbutton is off�
For more information on solar power,

page 6-10�
The solar panels and charge controller are
designed to help maintain a battery charge, and
are limited in their ability to provide a charge to
the battery. Additionally, the solar panels will not
provide any charge to the batteries if the Battery

Power pushbutton is off.
