In
the
event
of
an
overload,
low
battery
voltage
or
overheating,
the
EN5
48
a
utomatically
shuts
down.
Battery Operating Time
Operating time will vary depending on the charge
level of the battery, its capacity and the power level
drawn by the particular AC load, USB load, or
combination of both. With a typical vehicle battery
and a 80W load, an operating time of 4 to 5 hours or
more can be expected.
CAUTION
Although
the
EN5
48
incorporates
protection
against
over-voltage,
it
may
still
be
damaged
if
the
input voltage
exceeds
16
V.
When
using a vehicle
battery
as a
power
source,
it
is
strongly
recommended
to
start
the
vehicle
every
hour
or
two
to
recharge
the
battery
before
its
capacity
drops
too
low. The
EN5
48
can
operate
while
the
engine is running, but the normal voltage drop that
occurs during starting of the engine may trigger the
inverter’s low voltage shutdown feature.
