Yes, that's not a multiple ground path, thats just good grounding of the
tower.  I believe these individual tower leg groundings are suposed to
all be bonded as well.  An example of multiple ground path on a PV
system would be installing a ground rod at the (pole mounted) array and
bonding the negative leg of the PV to ground at the array, and then
installing a seperate ground rod on the home wiring.  Now, you have the
possibility of a voltage potential developing (near-by lightning)
between the two grounds and it is carried through the conductors (and
charge controller, etc.) rather than through the ground wire.  Kurt
