Christopher:
I'm not sure I understand your logic. It seems you are saying: 1. Life is dangerous anyway; 2. Children have been exposed to dangerous voltages due to other people's poor workmanship or lax enforcement; 3. Performing safe and code compliant work is hard; 4. 240 VAC is more dangerous than 500 VDC. 5. Therefore, there is no obligation to address unsafe and code non-compliant situations in ground-mount PV systems. If I understand this correctly, we are not going to agree on this one. I think it is incumbent on all of us to aspire to higher standards of safety and I know it means working a little harder. It can be done.

This is not a main one in my opinion, and given that there are no good solutions indicates to me that it is mostly an unsolvable problem unless you wish to be impractical. All I asked for were products that could provide a solution. . I have inspected in several states with solar programs that will not enforce securing electrical enclosures in living spaces that have access to 240 v. I even seen this situation in a children's play room. I think that is more than a little more serious issue.
