In the event of an overload, low battery voltage or
overheating, the EN548 automatically 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 EN548 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 EN548 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.
