I think the system would be technically required to have an equipment
grounding conductor to connect to lighting fixtures made of conductive
material. I believe this is true regardless of voltage. If
these do not exist, and no metal boxes are in the system and it is only
12 V, then it might be compliant to exclude the ground. If it is
only a 12 volt system, I don't believe there is much danger, unless the
person has a pacemaker and goes barefoot on the ice. <br><br>
410.46 Methods of Grounding.<br>
Luminaires and equipment shall be mechanically connected to an equipment
grounding conductor as specified in 250.118 and sized in accordance with
250.122.<br><br>

For a low voltage 12v nominal system you can per code install a + and -
OC protection and no ground.<br>
But if it was me, I wouldn't ground it at all,<br><br>

<blockquote type=cite class=cite cite=""><font size=2>Sounds like a silly
question but is there any way to ground a small battery based PV system
serving a temporary fishing shack on the middle of a frozen lake? Around
here they call these 8' x 8' (or larger) shacks "ice houses".
One or more holes are augered through the ice for fishing lines. Some of
the shacks get remarkably fancy, almost luxurious (in a guy kind of way).
There is usually plenty of beer and snacks. Sometimes fish, too. The
shacks get set in place as soon as the ice is solid (4-6" thick) and
they may stay there for several months. It's a home away from home for a
lot of upper midwest folks in the winter. Some like the idea of a small
solar powered battery system for light, CD player, TV, etc. There's no
earth around for hundreds of yards, even miles.<br>
