4. PROTECTION FEATURES
Our power inverters are equipped with numerous protection features to
guarantee safe and trouble-free operation:
Low battery alarm
Alerts you if the battery has become
discharged to 10.5V or lower.
Low battery voltage shutdown
Shuts the inverter down automatically if
the battery voltage drops below 9.5
volts. This feature protects the battery
from being completely discharged.
High battery voltage shutdown
Shuts the inverter down automatically if
the input voltage rises to 15.5 volts or
more.
Over load shutdown
Shuts the inverter down automatically if
the loads connected to the inverter
exceed the inverter’s operating limits.
Over thermal shutdown
Shuts the inverter down automatically if
its internal temperature rises above an
unacceptable level.
Output short circuit shutdown
Shuts the inverter down automatically if
a short circuit is detected in the
circuitry connected to the inverter’s
output.
Reverse polarity protection
If wrong polarity connection, the
internal fuse shall blow out.
Earth Fault Protection
The inverter complies with the
standard current leakage allowance.
When large current leakage to earth
terminal occurs, the protection circuit
activated and shut down the inverter,
which prevent electric shock to human.
Turn off the inverter, unplug the fault
AC appliances and then turn ON is the
only way to restart it.
Notes: All protection is automatically recovered. To protect the battery, if the unit needs to be
restarted after lower voltage protection, the voltage of DC input factory setting: modified sine
wave inverter is 11.8V.
