Looking for a little guidance!
I'm planning to install solar panels on my floating boathouse roof at my off-grid cabin. DIY project into a second charge controller of an existing system. 6 panels, roughly 1750W total.
A couple questions have come up because of this
1) What should I ground the panel frames to? Into a ground rod in the lake? Should this be bonded to the main cabin ground (probably 100 ft away)
2) All those articles about electric shock drowning got me thinking. Open Circuit voltage of three panels in series is almost 120V DC. If power from the shore TO the boathouse (AC from the inverter) runs through a GFI, is there something similar for the DC circuit from the panels to the shore. Or am I overthinking?
Thanks
