Grounding solar panels with PIP5048-GK

I'm pretty sure grounding the frames of the PV array is not a problem, in fact required for a safe installation.


  You are quite correct about grounding the PV frames. They are indeed lightning rods of large scale. Better to send the awesome amount of power from a lightning bolt directly to ground than anywhere else... Breakers and lightning arrestors can and do fail. Ive been 100% off grid for 18 years and have built many systems. Be safe out there. The only thing worse than losing everything to a fire is going with it.
