4. PROTECTION FEATURES:

Our Power inverters are equipped with numerous protection features to guarantee
safe and trouble-free operation:
✔ Soft Start
✔ Protection against overload and shortcircuit
✔ Low battery alarm
✔ Protection against polarity inversion and overtemperature
Low Battery Alarm
Low Battery Voltage
Shutdown
High Battery Voltage
Shutdown
Over Load Shutdown
Over Thermal Shutdown
Output Short Circuit
Shutdown
Reverse Polarity
Protection
Earth Fault Protection
Notes: All protection is automatically recovered.
Alerts you if the battery has become discharged to
10.5V or 21V.
Alert is done by an internal Buzzer "beep".
Shuts the inverter down automatically if the battery
voltage drops below 9.5V or 19V. This feature protects
the battery from being completely discharged.
Shuts the inverter down automatically if the input
voltage rises to 15.5V or 31V.
The inverter shuts down automatically if the loads
connected to the inverter exceed the inverter operating
limits.
The inverter shuts down automatically if its internal
temperature rises above an unacceptable level.
The inverter shuts down automatically if a short circuit
is detected in the circuitry connected to the inverter
output.
In case of wrong polarity connection, the internal fuse
shall blow out.
The inverter complies with the standard current leakage
allowance. When large current leakage to earth terminal
occurs, the protection circuit will activate and shut
down the inverter, to avoid the danger of electric shock.
Turn off the inverter, unplug the fault AC appliances
and then turn ON again to restart it.
