Orientation of inverter

The fans blow out to draw the air from the vents on the other end.
Fans do not push air through a device. They pull the air flow.

Not always true although it is common. Both configurations are used. It can depend on choice or application. There is a lot of back and forth of which way is better. One example would be an RF amplifier I have. The chimneys around the tubes are designed for air to be pushed through with positive pressure in the plenum. This means that as long as the fan can produce enough pressure that both tubes are cooled equally even if one is closer to the fan or the plenum is not perfectly even.

6 or twenty sides. Fan side NOT up. Drip shield would work. The fans on my Samlex push air through the inverter.

Page 36. “ . The fans suck cool air from air intake openings in the front and bottom (17A, 17B in Fig 6.1) and expels hot air through the exhaust openings next to
the fans (6, Fig 6.1). ”

That was painful. I waited on hold for two hours and five minutes to talk with Renogy customer service re: air flow on the inverter. The answer is: fan blows outward, sucking air in from the opposite side.

well congratulations. I'm so glad you won. Now thinking about it, I don't think the fans have ever switched on while I used the inverter. I only use it few minutes at time.

Thank you for starting this thread and supplying the answers or getting them supplied. This makes my life so much easier on my build, as I want the inverter to pull air away from the scc and now I know which way to point it when it arrives on Wednesday.
