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.
