Strange noise-Solar?

[clemdogmom]

Every night shortly after sundown I hear a noise from under my sofa. There is a solar panel on my recently purchased 2002 25' safari. Sounds like a fan running back behind the fuse box. Is this normal? Should I worry? Should I take some action?

Sounds like your converter. Are you plugged into shore power when this occurs?

Maybe a cooling fan on you power converter?

Yes, I am plugged in to shore power. I assume it is extra power being dumped? Could there be such a thing?

I carry my mobility scooter in the back of my TV, Dodge Durango. When I need to recharge Scooter I run a heavy duty electric cord to the back of the Dodge. I am trying to convince fellow campers that I have an electric power assist car. Now how to link excess solar power into this wild story???

It's the fan on your converter supplying 12 to the trailer systems and keeping the batts topped off.

I hear my converter cooling fan more when I have more 12 volt accessories. More lights on in the evening? The converter warms up while doing its job and the fan comes on more.
