Power Management Breakers; Power Management Fuse Center; Solar System - Airstream Trade Wind Owner's Manual

The battery bank is mounted to the underside of the
trailer, housed in a tray behind the fresh water tank
near the rear wheels� For important battery information,
see Batteries on page 5-12�
leads are routed through the floor into the Power
Board area to a large red Anderson connector labeled
Emergency Disconnect; see Emergency Battery
Disconnect/Battery Removal on page 5-13�
Cables from the other side of the emergency
disconnect are connected to a stud-mounted 400A
AMG main inlet fuse that protects the entire 12 volt
system ahead of the remotely operated battery
disconnect switch; see Battery Disconnect Switch on
page 5-12�
The disconnect switch controls 12 VDC battery
power to the MultiPlus-II inverter/charger and 12
VDC distribution panel� When the disconnect switch
is turned off, all systems running on 12 VDC power
will be off� However, the power management system
will remain active so the tow vehicle and solar system
can still charge the battery bank� The disconnect
switch must be on to charge the batteries via shoreline
connection�

Power Management Breakers

There are three 50A push-to-trip/reset breakers in
the power board only to be used by qualified service
technicians to isolate specific circuits for maintenance
(listed below)� To manually trip the circuit breaker and
disconnect power to the labeled circuit, press the round
button on the top of the breaker, which causes a reset
switch to pop out� Push the switch back into the recess
to reset the breaker�
• 24-Hour power Breaker - can be manually tripped
to disconnect power to the front end board, trailer
brakes, hitch jack, and tow vehicle battery charging
circuit� It also disconnects the main battery
disconnect, Victron Cerbo, and Victron Shunt�
• Solar Disconnect Breaker - can be manually
tripped to disconnect incoming solar charge
supplied by the solar controller�
• 12 VDC Power Distribution Breaker - can be
manually tripped to disconnect the 12 volt current
supplied to the 12 VDC distribution panel by the
MultiPlus-II unit�
WARNING
Do NOT tow the trailer with the 24-Hour Breaker
tripped. The breakaway switch will NOT activate
the brakes to stop the trailer if it detaches from
the tow vehicle in an emergency.

NOTICE
If the 24-hour Power Breaker is tripped, state-
of-charge will be lost until the batteries are fully
recharged to regain calibration.

Power Management Fuse Center

Fuses for the Victron Cerbo GX, Victron SmartShunt,
and cooling fan are located under the roadside sofa on
the Power Board (see previous page)� If you replace a
blown fuse and it immediately blows again, refer to a
qualified service technician to correct the problem.

Solar System

The rooftop solar panels installed on your Airstream
help maintain battery health, reduce operating
expenses, and extend the life of the batteries� You can
remotely monitor the system;
on page 5-16� To optimize solar charging, ensure the
panels are clean and not shaded by trees or structures
that might block the sun�
The solar system's solar charge controller gathers
energy from the individual solar panels and stores it in
the batteries� The battery disconnect switch does not
need to be on for solar charging� The system charges
the lithium battery bank using an adaptive two-stage
charging process:
• Bulk - the controller delivers as much charge
current as possible to quickly recharge the
batteries�
• Float - voltage is applied to the batteries to
maintain them in a fully charged state�
In addition to the factory-installed solar panels, a quick
plug-in port suitable for a portable solar charging kit
has been pre-wired at the front of the unit near the
propane tanks� Portable solar panel kits MUST include
a solar controller set to a Lithium profile and cannot
have an output of more than 15 amps� The solar port
is fused at 15 amps under the bed near the front of the
trailer; see 12-Volt Main Schematic on page 8-17�
NOTICE
Do not unlock or tamper with the MPPT Control
system settings. Changes to the settings will
negatively affect the system's performance and
could damage your batteries.
NOTE
The solar system provides a charge to the
battery bank but it is still possible to use more
power than the solar panels can provide.
