[RE-wrenches] Static shock

[jay peltz]

Hi all,

Here is a new question. 
I believe it's static electricity. 

System:  standalone 2 x 44voc  165 watt modules in parallel
Powering a pump sq flex( yea installer didn't do it right) dry ground. 
No batteries or any other power in the area, no LCB or other electronics. 
Pole mount, dpw in concrete with galvy pole
Wires are not attached to pole/ rack in any way
It's been very low humidity 5-10%, with 10-20 mph wind
No rain totally dry

Here is what happened. 
Person with one hand touched pole and and other hand touched the USE-2 insulated wire from the modules, got way shocked. Checked the wire no cracks etc and again 44voc max

Happened a second time, but this time his sleeve brushed the pole while he was moving the wires, again shocked. 

Again, I think it's static as I have no other explanation. This kind of weather is unknown where I live. I now live in a true desert vs a rain forest and never moved. 

Thoughts?

Thanks

Jay
