Is this normal?
I imagine it would be more effective to suck in cooler air from below and exhaust it above.
My EasySolar II GX 48/3000/35-32 rapidly derates (or at least, gives Overload warnings) even under modest load, even in winter in an unheated shipping container with ambient temperature ~10C. The fan runs, but blows a little hot air out below (working against the natural buoyancy of hot air). The easySolar is probably getting hot inside. Is the airflow direction a factor in this?

Hi i think you should open it en check direction of the fan, normally there are markings on the fan chassis that state flow direction, it should blow out warm air from the top
If not turn the fan around
Once you have forced cooling it makes little difference to the heat transfer efficiency if it is up, down or sideways, the air velocity significantly exceeds the that generated by natural convection.
The effect seems to be only to blow a little hot air out of the bottom, despite the fan running as hard as you would expect.
Is there a picture anywhere of what to expect inside the case?
