[RE-wrenches] Grounding system for a shack on a frozen lake?

[Dave Click]

Per 690.41 you probably wouldn't need to ground it for a system like 
this, but I like the idea of dropping a ground rod down into the water. 
Then curve the end and find a big worm, of course.

**
690.41 System Grounding. For a photovoltaic power source, one conductor 
of a 2-wire system with a photovoltaic system voltage over 50 volts and 
the reference (center tap) conductor of a bipolar system shall be 
solidly grounded or shall use other methods that accomplish equivalent 
system protection in accordance with 250.4(A) and that utilize equipment 
listed and identified for the use.
