I need help and I think eltronics is the the answer. I have a caravan that has a aluminum frame and insulated with fibreglass on the outsides and inside and very good insulation foam in-between. When it gets cold the cold travels through the aluminium (great conductor) and causes condensation on the inside of the van (drips water) on beding in cupboards ect ext. I think the only way to prevent this problem is to send a current through the frame to cause heat (like a car demister in the rear window) and stop the conensation problem. So do you think a voltage / amperage regulator wold work ?? The van has 450watts of solar and 360 amps of battery power. Naturaly the problems is only when it is cold and the humidity is high. so would also need to be on a timer and draw low voltage/ amperage.
