About What meter should be used for photovoltaic panel grounding
A mounting pole can be used as the ground, if installed correctly. However, an earth resistance meter should be used to measure the resistance from the system ground to the actual earth.

Use a CAT III meter with a voltage rating higher than the PV system voltage (like the Fluke 393). Attach the negative lead from your meter to the negative busbar using an alligator clip.
Follow the below steps on how to inspect the grounding system regularly:Use a voltmeter or other similar device to test the continuity between the grounding rod and the solar panel array.If there is no continuity, check all connections and make sure they are tight and free of any oxidation.

6 FAQs about [What meter should be used for photovoltaic panel grounding]
Should I ground my solar panel system?
By considering these additional factors, you can ensure your grounding system is tailored to your specific needs and maintains its effectiveness over time. Properly grounding your solar panel system is a critical step that should never be overlooked or rushed.
Do I need a ground resistance meter?
However, an earth resistance meter should be used to measure the resistance from the system ground to the actual earth. It is recommended that the ground system have a resistance less than 5Ω to ground. Note: Depending on the soil and site conditions, multiple ground rods may be required to achieve the required resistance.
What are equipment grounding requirements for PV systems?
Equipment grounding requirements for PV systems are covered in 690.43. These requirements include the bonding and grounding requirements for exposed metal parts of PV systems such as metallic module frames, electrical equipment, and conductor enclosures [690.43 (A)].
Do I need a grounding electrode for a PV array?
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.
How do I connect a Sol-Ark meter to a neutral meter?
In the house, the Sol-Ark and my critical loads panel Neutral are both tied/connected to my main panels Neutral. The main panel is bonded (ground and neutral connected together) there at the main where the meter base is on the outside of home. The ground there goes down to a ground rod near the home (about 3 feet from the meter base).
What bare copper wire should I use for solar panel grounding?
Throughout this guide, we’ve covered the key aspects of solar panel grounding, from understanding regulatory requirements to avoiding common mistakes. Remember, the most crucial takeaway is to always use #6 AWG bare copper wire for outdoor grounding. This simple yet vital detail can make the difference between passing and failing an inspection.
