That's why we introduce a high volt drop between inverter and meter point. Ideally the inverter should be as high as possible (that's why they are best put in the loft). The higher the volts can drop, the more chance they have of bouncing back up the pole. :rockon2:

Ah got it now, that is why some use long lengths of 2.5 so the volts will drop even more...

oh arse. I've been attaching them to a pole on top of the chimney pot, I assumed that was why they were outdoor rated.

Tricky one. Ideally you'd do this with a twin string inverter and use both strings to secure it. Single string units might be a bit unstable. Don't forget to bond the pole as Santa will extend the equipotential zone - outdoor rated sky hooks work best.
