Q: Is this controller outside mountable?

A: Yes, this controller is outside mountable, separating it from the many other controllers available. Mount out of the direct sunlight.This controller more than any other that I have seen is weather-resistant, it is encased in a hard epoxy resin and it says in the spec 1) "Mounted in a hard epoxy resin that offers substantial protection from the environment", 2) "Completely encapsulated for environmental protection (suitable for outdoor mounting)", 3) "Maximum environmental protection - ideal for outdoor mounting", and 4) "CORROSION: - The exposed terminal block is made of corrosion resistant nickel plated brass. This will endure most outdoor environments. When the ASC is in an excessively corrosive location, a coating of an oxide inhibitor should be applied to the terminals." and the housing/chassis is anodized aluminum and the unit has temperature compensation via the sensor.....

A picture is worth 1000 words...

Note: Pictured above is the ASC 12/16 AES. The technology is the same across all charge controllers in this family, therefore the ASC 12/4 controller being sold in this listing has the same casing and epoxy, which is what these pictures is demonstrating.

These pictures show that the controller is actually a solid block inside the epoxy resin, sealing the moisture out!
