Protections
The inverter has been provided with protections detailed below:
overload / Short circuit Shut Down
Theinvertercanprovideahigherthannormalinstantaneouspower(<1second)limited
tothesurgepowerratingoftheinverter.Also,theinvertercanprovidecontinuous
power limited to the continuous power rating of the inverter. If there is an overload
beyondthesespecifiedlimits,theACoutputoftheunitwillbeshutdownpermanently.

alarm will be sounded. The StatusLED(2)willcontinuetobeGREENandtheACoutput
voltage would continue to be available. This warning buzzer alarm indicates that the
battery is running low and that the inverter will be shut down after sometime if the
voltage at the inverter terminals further drops to 10 V for 12 V versions or 20V for 24V
versions.
