Whirring noise from inverter
It sounds as if there is a fan or something that comes on intermittently, anything to be concerned about?

- Check your battery too. Water should be covering the plates, no excessive gassing, the terminals should measure steady 13.2 to 13.7 volts.
If this is actually an inverter(vs converter) then disregard. - there is a fan, when the unit gets warm it comes on, might clean the blades ,and spin the blade it should turn free not stiff.
