[RE-wrenches] Sol-Ark 15k solar panel frame grounding

[Maverick Brown]

I usually get the 08 GFDI error when I haven’t bonded neutral to ground downstream. (Typically because I booted up the inverter after DC connection but before any AC wires are landed.) That goes away once it is fully commissioned. 

I get the F23 - Tz_GFCI_OC_Fault If is related to the PV array, leakage or bonding. 

I do always run a properly sized ground wire from the array to the inverter ground. 

Thank you,

Maverick

Where would be the suggested place to connect the equipment grounding conductor, and why does it make a difference? It would still be electrically bonded to the grounding terminal in the inverter.

The manual doesn't say anything about the DC side with respect to this error. It suggests it is an AC current leakage to ground. But Sol-Ark tech support suggested that I disconnect the PV to rule it out as a source of the fault.
