Bonding PV ground to detached garage Grounding Electrode

[goldfinch.electric]

Hi, I am installing a DC PV system on a detached garage. The garage has a 100 amp sub-panel run from the house and an auxiliary grounding electrode. My question is about bonding the PV overcurrent/disconnect panel to the #6 bare copper going to the grounding electrode of the garage. We also have run a EGC back to the inverter in the main house, where all will be bonded. We are on 2020 code cycle. Question. I installed a bond from the DC disconnect in the garage to the AC garage sub-panel grounding conductor. Is this bond needed or recommended? Thanks in advance for any thoughts on this confusing topic.



690.47 "A building or structure(s) supporting a PV system shall utilize a grounding electrode system installed in accordance with Part III of Article 250."
Check. The garage has its own GE installed.

​

690.43 Exposed noncurrent-carrying metal parts of PV module frames, electrical equipment, and conductor enclosures of PV systems shall be connected to an equipment grounding conductor in accordance with 250.134 or 250.136, regardless of voltage. Equipment grounding conductors and devices shall comply with 690.43(A) through (D).
