Fan inlet and outlet? Which side is which?

Hi guys, just wondering if anyone knows which side is the fan inlet and which side is the outlet?

AC200MAX

The inlet is the side that when running a small piece of tissue or toilet paper will be sucked towards the grill. The outlet would then be the opposite side.

On my ac200p, the only time i have ever caught the intake fan spinning is at P.O.S.T., but your tissue test plus deduction could work when the outflow fan kicks in during charging etc.

Connected 2000 white load to the inverter for 10 minutes and. All the fans will be running

Ha I expect they would be even in my colder climate! :]
