I’ve tested with multiple grounds. The kit came with a tester. The 120v energizer will put out 8-9k volts but the solar one is only pushing 2k volts.

I usually do the finger test lol!! If it’s a tingle not hard enough. The 120v one about puts me on the ground ha!

There are just places where I can’t reach with the 120v one though so was trying to see what others use.
