	**Additional issue for PV is that in cloudy conditions or when there is little sun (evening), if you get a fault, a breaker may not trip because current is too low. For this reason, specific ground fault protection is required. But, if it's a fuse to solid ground from - of PF to ground rod - why not just use a lower value fuse? I don't get it.		**Additional issue for PV is that in cloudy conditions or when there is little sun (evening), if you get a fault, a breaker may not trip because current is too low.
