voltage of at least
22Vdc
to activate the charge controller.
●
Ensure the total open circuit voltage of the panel array
does not exceed
150Vdc
. Excessive voltage will place the
charge controller into an overvoltage fault condition. This
can be cleared by unplugging the solar panels and
reducing the number of panels tied together.
●
Ensure that the AC load on the Vulcan does not exceed
the power output of the solar panels while they are
producing DC power from the sun. If the system load
exceeds the panel output at any given time, all panel
energy will be used to produce power for the AC loads.
System not charging from
the grid/shore power
source.
●
Check the grid/shore power supply circuit and breakers to
ensure
120Vac
is being provided to the Vulcan/Smart
Store.
●
If the supply breaker trips when the power restores and
loads are present, turn off the power switch at the front
of the Smart Store(s) to reduce the load circuit current.
●
If grid/shore power is present, check the plug connection
at the rear of the Vulcan unit and the plug connection at
the front of the Smart Store. Ensure the Smart Store AC
power switch is on.
Smart Store power share
not being seen by the
Vulcan.
●
Ensure that the Smart Store battery power on/off button
is depressed and illuminated. This will parallel balance
the Smart Store battery with the Vulcan system.
Low battery percentage
on the Vulcan unit.
●
The Vulcan unit needs to be charged from a grid/shore
power source, Solar panels or a fully charged Energy
Store or Smart Store.
Low state-of-charge on
the Energy Store and/or
Smart Store units.
The state-of-charge display is flashing a red or yellow LED to
indicate that the state-of-charge is 20% or less:
●
Connect the Smart Store to a grid/shore AC power
source.
●
Connect the Smart Store to solar panels with adequate
sun and placement.
●
Connect the Energy Store and/or Smart Store to a Vulcan
unit. Ensure that the Vulcan power on/off button is
depressed and illuminated. This will charge the Energy
Store and/or Smart Store.
