CAUTION
PHYSICAL INJURY HAZARD
This Vulcan unit is not intended for use by persons (including children) with reduced physical, sensory,
or mental capabilities or lack of experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible for their safety. Children should
be supervised to ensure that they do not play with the appliance.
Failure to follow these instructions can result in injury or equipment damage.
Vulcan is designed to work with the Sol Donum
™
Energy Store and Smart Store expansion
batteries. They incorporate short circuit, overvoltage, undervoltage, and temperature
protections and an ORing Diode circuit that allow Vulcan systems to scale up to 100kWh of
energy capacity.
IMPORTANT NOTE: Vulcan is not compatible with recharging from other 12Vdc sources. This can
result in damage to the unit and cables, as well as your vehicle or 12Vdc charging source.
Energy Stores
Energy Stores are batteries that are used to expand Vulcan’s battery capacity for greater load
runtimes. They are hot-swappable, meaning that they can be plugged into and unplugged from
a Vulcan unit at any time while the Vulcan is powered up or powered down. They are connected
in a daisy chain using the Sol Donum
™
supplied 'Power Bus' expansion cables to provide
additional battery power to Vulcan units. The Smart Store can self-charge from solar panels or
grid/shore power, which increases overall Vulcan system solar and grid/shore input power to
reduce charging times and increase the AC load that can be covered by solar panels energy
harvesting.
CAUTION
Always connect Power Bus cables to the appropriate color coded ports between units. Never cross or
short circuit the
RED
and BLACK cable connections.
