Inverter cooling fan

Excellent choice! The Outback units are built like tanks and should last forever. Note that it weighs 60lb, so there's probably enough heat sink in that mass you may not need to ventilate it. I doubt the mfr just forgot about cooling an inverter that expensive.

I have the 3648A, and I never hear its fan, nor do I know if it even has one. It's in the basement, not a small enclosed space however.
