FIG 1: GROUNDING THE MODULES, TRACKER FRAME, DRIVE AND MOUNTING PIPE The array equipment-grounding conductors, for the modules, tracker frame, drive and mounting-pipe, should terminate at one location—probably a grounding terminal strip in the junction/combiner box. Then, there should be a conductor from this point to the grounding electrode (ground rod). The steps are: • The frame of every module is interconnected with grounding wire. • The module grounding wire ties into the tracker frame on the torque tube or struts. • A flexible loop of grounding wire continues from the torque tube to the base of the drive. • The ground wire continues to the mounting pipe or combiner box that is bonded to the pipe. • The ground wire goes down the pole and is bonded to an 8-foot copper ground rod. • The ground rod is set in the earth outside of the concrete foundation of the pipe. • Do not rely on the mounting pipe to act as a ground rod. (Older <strong>AZ</strong>200 shown for illustration purposes) 36
FIG 2: TYPICAL GROUNDING OF A TRACKER TO THE BATTERY BANK/POWERCENTER. • The modules, Wattsun Tracker, and mounting pipe are grounded as shown in Figure 1. • The normal, (primary bond) negative-to-ground bonding is required in the power center or ground-fault device. • The negative current-carrying (PV Negative) conductor is bonded (connected) to the grounding system at the power center or charge controller. • An equipment-grounding conductor is run from the PV array to the power center or charge controller. WARNING! If you ground according to FIG 2, you must ground the PV Negative at the power center, not at the array. There can only be one ground for the current carrying conductor (PV Negative) in this situation. 37
