Here is where the electric fence part comes in.... the paddocks that will be fed by the well are too far away from hydro to have a traditional plug in fencer. We tried 2 different brands of solar fencers, but just don't get the overall readings that we do out of the plug in type (we compared the two by running a generator and switching between them - the plug-in type kicked butt).
So, what I was thinking of doing was to put a plug in fencer in my well shack and run off a second inverter (1 - to separate the two loads and prevent brown-outs on the fencer, 2 - if the well pump fries the inverter I don't want the fence down to). Then I will bury an insulated power lead from the fencer to the fence (about 50-60').
My question is, Can I drop a ground rod into the well and use the contact of the water as an earth ground for the fence??
