HEAT DISPERSAL
The inverter generates heat while it is working. This is not a malfunction. However,
if the inverter gets too hot while working, it will turn off by itself. Position the
inverter where air flows freely around it to allow the heat to disperse. The inverter's
thermal protection prevents it from operating when its temperature exceeds
130ºF ± 10ºF.
