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.
