VOLTA SYSTEM OVERVIEW
A Volta System typically contains an energy storage source (VIP or VSP Energy
Storage Pack), an alternator for charging during driving operations, an inverter/
charger for shore power charging and 120 VAC power distribution, and con-
verters to create DC power at various voltages. Your actual system may vary in
size, complexity, power distribution devices used, or other application specific
variations.
The Volta System and power distribution systems are similar in complexity
to a vehicle engine or generator. Therefore, only Volta technicians or trained
professionals with in-depth knowledge of Volta Systems should service these
components.
The appearance and availability of components in
your Volta System may vary from what is shown.

Volta System Components
Your Volta System may be configured with the following options:
•VIP or VSP (Energy Storage Pack): The Pack is the energy source for
your Volta System. A 14-gauge steel housing protects the lithium-ion
cells, and an internal Battery Management System monitors the system,
balances the cells, and controls energy output.
•Inverter/Charger: The inverter changes the pack’s energy from direct
current (DC) into alternating current (AC) to power the vehicle’s 120V AC
devices (air conditioner, heater, cook top, etc.). The inverter also converts
shore power (AC) to direct current (DC) for charging the pack.
•Inverter Control Panel: Control, monitor, and adjust the Volta System
inverter via the Inverter Control Panel.
•DC-DC Converter: The DC-DC converter drops the pack’s energy from
58V DC to power your vehicle’s 12V DC or 24V DC devices (vehicle
electronics, lights, refrigerator, etc.).
•Secondary Alternator: The high-powered, secondary alternator provides
charging power directly from your vehicle’s engine to the pack.
•Solar Controller: The solar controller regulates solar power input from
external solar panels into a stable, usable form of energy to charge the
pack.
•On/Off Pushbutton: Press the On/Off pushbutton to turn on or off the
Volta System.
•SOC Gauge: Provides an approximate reading of how much energy
remains in the pack. It also serves as a simple communication center for
basic system states through color changes and flash codes.
•Touchscreen: Use the Touchscreen to monitor and control the Volta
System.

CHARGING THE SYSTEM AND INCREASING SYSTEM
RUNTIME
The Volta System accepts charge from the sources described in the following
sections. Monitor the SOC Gauge, the Inverter Control Panel, or the Touchscreen
for any alerts that may prevent charging.
The Volta System only charges when required. There may be several factors
preventing charging, even while connected to a charge source. The most
common reasons are the energy storage pack is too cold to charge, or the BMS
is inhibiting charge because of a high enough SOC.
System Runtime
Similar to fuel tank levels responding to driving style, the time it takes to drain an
Energy Storage Pack from “Full” to “Empty” depends on usage. The two largest
loads in a vehicle that affect the runtime are typically heating and cooling. The
more the heating and cooling systems run to maintain the desired temperature
inside the vehicle, the more energy is used.
To maximize runtime:
•Turn off the inverter if 120 VAC loads are not required: When 120 VAC
devices (air conditioner, heater, cooktop, etc.) are not in use, turn off the
inverter via the Inverter Control Panel or Touchscreen.
•Increase the thermostat in warm climates: Increasing the desired
vehicle temperature reduces the amount of time the air conditioner
compressor needs to run in warm climates.
•Decrease the thermostat in cool climates: Decreasing the desired
vehicle temperature reduces the amount of time the heating system
needs to run in cold climates. Generally, heating using electricity uses
almost twice the energy as cooling.
Charging via Shore Power
Volta recommends a minimum 120V/30A rated shore power cord less than 50 ft.
in length. The OEM should follow NEC or RVIA guidelines for the specific appli-
cation requirements.
When plugged into shore power, the Energy Storage Pack samples incoming
power for a few seconds to ensure uniformity requirements are met. If incoming
power meets the requirements, the Volta System turns on and begins charging
the Energy Storage Pack.
If the Volta System does not turn on, or the Energy Storage Pack does not begin
to charge, the incoming power is likely not meeting the Volta System require-
ments. This feature protects the vehicle from brown outs due to insufficient
power. Additionally, the system may not accept a charge if plugged into an
electronic surge protector.
The rate at which the Volta System charges from shore power depends on your
system configuration and the settings chosen on the Inverter Control Panel or

VPS-DOS-TR-06-E / Rev 01
3-May-2022
Volta Power Systems Page 17 of 41
Touchscreen. Refer to Inverter Screen on page 28 or Max Branch Amps
(Charger Current Limit) Setting on page 22 for details on changing the
charge rate selection.
120 VAC vs 240 VAC Outlets
Warning: Do not connect the Volta System to a 240 VAC outlet.
Connecting to a 240 VAC outlet may result in permanent damage
not covered by the Volta Power Systems warranty.
RV owners are familiar with 30A outlets, so they may want to install a 30A
outlet at their home. Unless this outlet is specifically installed as an RV
outlet, the electrician may mistakenly wire the outlet to be 240 VAC, which
is typically used for home appliances, such as electric dryers. RV outlets are
30A 120 VAC, but home 30A outlets are commonly 240 VAC. Do not connect
to a 240 VAC outlet.
Charging via the Secondary Alternator
A Volta secondary alternator powers the vehicle’s electrical features while simul-
taneously charging the Energy Storage Pack when all of the following occur:
•The vehicle is running.
•The vehicle is maintaining a high enough RPM.
•The Volta System is turned on.
If the engine does not sustain a high enough RPM, the BMS sends a signal to
turn off the alternator until the BMS determines it is appropriate to turn on the
alternator.
Charging via Generator
Similarly to charging via shore power, the Energy Storage Pack can charge via
connection to a generator. An on-board RV generator or a traditional generator
can charge the Energy Storage Pack if the generator meets the inverter/char-
ger’s requirements, such as AC input range and frequency.
When plugged into a generator, the inverter samples incoming power for a few
seconds to ensure uniformity requirements are met. If incoming power meets
the requirements, the Volta System turns on and begins charging the Energy
Storage Pack.
If the pack does not charge from a generator, this condition may be due to
unclean or unstable power from the generator.
The Volta System can be integrated with a generator using an auto-start and
auto-shutoff feature, creating a hybridized charging system that increases
efficiency for the Volta System and the generator.
Charging via Solar Power
Your vehicle may be equipped with solar panels that supply additional energy to
the Energy Storage Pack when there is sufficient sunlight.
The available charge from solar power varies by the capacity and number of
solar panels on your vehicle.

VPS-DOS-TR-06-E / Rev 01
3-May-2022
Volta Power Systems Page 18 of 41
The secondary alternator or a shore power connection are more effective in
charging the pack than solar power. The solar charging system is primarily used
to increase the time needed between charges.
Solar Controller LED Indicators
Your system may include a solar controller with LEDs for monitoring the
system. The solar controller has two LEDs that indicate the solar charging
status. The following represent the typical LED indicator combinations:
If both lights are red, it indicates the system is not charging. This can be
caused by the following:
•The system is fully charged.
•The pack is too cold to charge.
•The solar controller’s internal temperature is too high.
•Insufficient sunlight to charge the system or the panels are dirty.

RESETTING FAULTS AND SYSTEM EMPTY FAULTS
How to Reset a Fault
When the SOC gauge is slowly blinking red, a system fault is present. To attempt
to reset any fault, press the On/Off pushbutton to turn off the Volta System, wait
30 seconds, then press the On/Off button again.
If the fault does not clear, and the pack is above 0% on the SOC gauge, there is a
fault that will need to be checked by a certified technician. Contact the vehicle
OEM, Dealership, or other Volta approved technician.
How to Reset from System Empty Fault
The Battery Management System shuts down the Volta System if the pack
reaches a very low voltage limit or 0% State-of-Charge (SOC). When the Volta
System reaches 0% SOC, the SOC gauge slowly flashes red and the needle will
be at 0%. Do not attempt to turn on the system until a charge source is connect-
ed.
To reset your system after a system empty fault:
1. Turn off the vehicle and disconnect shore power.
2. Press the On/Off button to turn off the Volta System, if not off already.
3. Wait 30 seconds, then press the On/Off button to turn the Volta System
on.
4. Within 120 seconds, connect a charging source: Connect your vehicle to
shore power or start the vehicle and run at the high idle setpoint.
NOTE: If the battery system does not sense incoming power within 120
seconds from being re-awakened, it will go back to sleep. Restart the
procedure if this occurs.
5. If charging via shore power, ensure the appropriate charge rate is
selected via the Touchscreen or the Inverter Control Panel. Refer to
Inverter Screen on page 28 or Max Branch Amps (Charger Current
Limit) Setting on page 22 for details on changing the charge rate
selection.
6. Charge the system to a SOC of greater than 20% before turning off the
system, unplugging from shore power, or turning off the vehicle.
If a system reset is successful, and the system empty fault is corrected, the SOC
gauge will be solid red (not flashing). If this reset does not correct the System
Empty Fault, please contact the vehicle OEM, Dealership, or other Volta ap-
proved technician.
Perform the recovery procedure as soon as possible. Failure to recover from a
low voltage shutdown will result in further pack discharge, which may require
service from a Volta technician.
Consider the Energy Storage Pack temperature when recovering from zero SOC.
The Volta System will not charge if the Energy Storage Pack is too cold. Refer to
Cold Temperature Operation on page 31 for additional details and strate-
gies.

INVERTER CONTROL PANEL
Inverter Overview
Depending on your Volta System configuration, you may have an Inverter
Control Panel to control your inverter.
The inverter changes energy from the Energy Storage Pack from direct current
(DC) into alternating current (AC) to power the vehicle’s 120 VAC devices (air
conditioner, heater, cooktop, etc.).
Turn the inverter on or off using the On/Off button on the Inverter Control Panel
(see image above). To get the most out of your system’s charge, turn off the
inverter when not using 120 VAC devices. When connected to shore power, the
inverter cannot be turned off.
Control your inverter, adjust settings, and monitor energy usage via the Inverter
Controller with LCD screen.
Run Mode
The inverter turns on automatically each time the Volta System is turned on via
the Volta On/Off pushbutton. While the inverter is on, it is in Run Mode, meaning
that it is actively converting energy from the Energy Storage Pack.
While in Run Mode, the inverter controller displays the following:
This example shows the inverter is on, the load is consuming 1500 watts, and the
battery voltage is at 57.4 volts.
Standby Mode
The inverter enters Standby mode when your vehicle connects to shore power.
When in Standby Mode, the inverter charges the Energy Storage Pack (if
needed) and all devices are powered via shore power. While in Standby mode,
