Volta System Storage

Long Term Storage (Greater than 3 months)

Preparations should be made to protect the life
and performance of the Flex Pack when not in use�
When leaving the vehicle in storage, turn OFF the
Volta System by pressing the Battery Power On/Off
pushbutton�
To prepare for long-term storage:
1� Fully charge the house battery (Flex Pack), or at
minimum charge to above 70%�
2� Press the Battery Power On/Off pushbutton and
verify that the pushbutton LED and touchscreen
turn off, indicating the Volta System is off�
3� Turn on the Volta System every three months
to verify the pack is maintaining a high State-of-
Charge (SOC)� If necessary, charge the system to
above 70% SOC before storing the vehicle again�
Failure to turn off the Volta System before storing
your vehicle long term (greater than 3 months) will
cause the Flex Pack(s) charge to deplete faster,
even if all loads on the system are removed, which
can cause permanent damage to the Flex Pack.
Do not store the Volta System at low State-of-
Charge. The system is designed with a limited
energy reserve, in case the system is left on and
the low voltage shutdown occurs. This reserve
may last for three months until irreversible damage
could occur. Neglecting system maintenance and
allowing the Flex Pack to come to this state will
result in voiding the warranty.
To protect the Flex Pack, avoid using or storing
the Flex Pack at or above 134°F (57°C). Storage
of the Flex Pack at elevated temperatures is not
recommended, as it will reduce the lifetime and
capacity of the Flex Pack.
NOTE
It is possible to leave the touring coach plugged in
for long-term storage, but it is unnecessary to do
so with a full charge or greater than 70% charge,
following the instructions above.

2� Ensure the appropriate charge rate is selected�
For more information about setting the charge rate
on the Volta touchscreen;
Screen on page 5-16�

OFF the system� Verify that the pushbutton LED
and touchscreen turn off, indicating that the Volta
System is off�
4� Connect the vehicle to shore power to enter
Charge Only Mode�
While in Charge Only Mode:
• The Battery Power pushbutton LED will flash green
indicating the system is in Charge Only Mode� The
Volta System turns on, charges as needed, and
maintains an operational state�
• The battery heater will operate in cold climates
when connected to shore power and the
temperatures drop below 59°F/15°C�
• If shoreline power is lost the Flex Pack System
turns off to retain charge�
To protect the Flex Pack, avoid using or storing
the Flex Pack at or above 134°F (57°C). Storage
of the Flex Pack at elevated temperatures is not
recommended, as it will reduce the lifetime and
capacity of the Flex Pack.

Brief Storage Periods

For shorter periods of time, the Volta System can be
left on if you are connected to shore power in order
to keep the refrigerator cold� However, if the cord
is accidently knocked loose or a breaker trips, the
system will be running on battery power only, which
could result in a dead battery if not caught in time� If
you plan to leave the system on and unattended, take
precautions to prevent such circumstances�
To protect the Flex Pack, avoid using or storing
the Flex Pack at or above 134°F (57°C). Storage
of the Flex Pack at elevated temperatures is not
recommended, as it will reduce the lifetime and
capacity of the Flex Pack.
