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.
