Electrical System Operation

Power System Overview

Your touring coach has a powerful 12,000 watt-hour
(12 kilowatt-hour) lithium-ion 58 volt battery pack (Flex
Pack), a 3,200 watt pure sine wave inverter, two 30
amp converters, and a secondary 58 volt 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 Volta
Power System, read the VOLTA FLEX SYSTEM
USER MANUAL in your Owner's Packet for important
warnings/limits, operating instructions, and tips
for using the system� Visit Volta's support and
education web page, where you will find a series
of how-to videos, literature, and FAQs:

Volta Flex System Components

Flex Pack

The Flex Pack is the source of house energy for your
touring coach� It houses a 58 volt lithium-ion cell
battery pack and Battery Management System (BMS)�

Battery Management System (BMS)

An internal component of the Flex Pack that monitors,
optimizes and protects the Flex Pack, and performs
various charging functions�

Inverter/Charger

The inverter/charger converts direct current (DC)
battery power to alternating current (AC) power to run
appliances and outlets/receptacles�
The inverter/charger also converts shoreline AC power
to DC power to charge the Flex Pack battery pack�
Since electrical service varies from one source to
the next, to prevent the shore-power breakers from
tripping, it's important to ensure that your system's
charge amps are properly adjusted� To change this
setting, navigate to the Inverter/Charger screen on the
Volta touchscreen panel� Press the arrows to select the
charge rate that matches your chosen power source�
For more information on how to operate the inverter/
charger using the Volta touchscreen interface,

outlet. Connecting to a 240 VAC outlet may result
in permanent damage not covered by warranty.
inverter will draw a small amount of power from
the battery. Turn the inverter off if you are not
using outlets or running air conditioning or other

DC-DC Converter

Converts the battery's voltage from 58 volt direct
current (DC) to 12 volt DC to power 12 volt devices like
LED lights, electronics, and the refrigerator�

Secondary Alternator

https://
The powerful 58 volt secondary alternator charges the
Flex Pack (house battery) simply by driving� It is also
the fastest means to charge the battery� A shoreline
connection can provide at maximum a 30A charge rate,
whereas the alternator is capable of producing 100+
amps;
