Blow the unit out, dust builds up over time resulting in similar behaviour, clean the filters as well. that normally takes care of the problem. 

Hello Jaco, thank you! Where does the filters sits? Do I need to disconnect the inverter to blow out and clean filters?

Its more like a fine steel mesh, at the bottom where it sucks the air in and on both sides on the top where it vents the air out. those gets blocked.

You can just switch it off, both AC and DC supplies. 

 

EDIT: And if your have the Heat Sink part on top, ensure those are clean as well. 

Hello Jaco, thank you. I checked this morning mine don't have filters the vents is just open without a filter on the sides, I will also just check if all the fans is running fine.

How can I check the firmware? and is there newer firmware out?
