Key points from the NEC: The code requires all non-current-carrying metal parts of the solar PV system to be grounded. It specifies the minimum size of grounding conductors (more on this later). The NEC also outlines requirements for grounding electrodes (like ground rods) and how they should be installed.
In a battery based system, it is recommended to connect one of the current-carrying conductors as close to the battery as possible, as the battery is typically the greatest DC source of power. *As with chassis grounds, one reason to ground the electrical system is for safety; however, electrical transients are another major reason.*
While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter’s grounding bus bar.
At one time in the U.S., the dc circuits of PV arrays were required to be grounded; and the inverter provided an optimal location for doing this. To ground the dc system, one circuit conductor was connected to ground, usually through a ground-fault protective device, and then to a grounding electrode system.
Now, you’ll connect your solar panels and racking to the grounding wire: If your racking system is UL-listed for bonding, connect the grounding conductor to one rail in each row. If not, attach a grounding lug to each panel frame and racking component. Connect these lugs to your main grounding wire.
For example, positive- or negative-grounded PV modules will cause current leakage to the inverter. Grounding of the PV module frame is permitted and frequently required by local law. Hello, As the title states, should your battery bank be tied to your ground?
