Re: [RE-wrenches] Sol-Ark 15k solar panel frame grounding
The reason for less white PV wire I believe is due to less UV resistance capability. Time showed that it was inferior to black. Using black in lieu of white, and color coding at the terminal connections is an allowed practice and that is why less white PV wire is used I believe.

Re: [RE-wrenches] Sol-Ark 15k solar panel frame grounding
SolArk arrays are ungrounded. However, because they are transformerless, when the inverter is operating, there is a reference to ground on the DC side via the AC side neutral bond to ground. So, a ground fault on the AC side will also cause a GF error. Many transformerless interactive inverters are using Isolation Resistance testing to detect ground fault, rather than measuring current. Sol-Ark doesn't have any literature to say what method of GF detection they use, but it is unlikely there is a reference to ground via the GF detection method. In any case, they aren't solidly grounded, and none of the DC conductors should be white or grey, they can both be hot with respect to ground.

2020 NEC® identification requirements in 690.31(B)(2) state that "Only solidly grounded PV system dc circuit conductors shall be marked in accordance with 200.6." (200.6 is Means of Identifying Grounded Conductors") If the circuit is nonsolidly grounded, then positive conductors can be identified with +, POSITIVE, or POS if color coding is not being used; if it is, they can be any color other than green white or gray. Nonsolidly grounded negative conductors can be identified with -, NEGATIVE, or NEG if color coding is not being used; if it is they can be any color other than green, white, gray, or red.

Re: [RE-wrenches] Sol-Ark 15k solar panel frame grounding
Hi Jason, You should be able to land your PV EGC in the inverter ground bar. You could do a quick resistance check to verify the +, - PV Is there a bond somewhere (upstream service panel or in the Sol-Ark itself) between ground and neutral? If not, this can cause this fault.

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

[RE-wrenches] Sol-Ark 15k solar panel frame grounding
Can anybody clarify the following instruction from the manual? "GND the panel MOUNTS/FRAMES to any GND outside the circuit via 12AWG wire" Does this mean do not connect the array equipment grounding conductor to the grounding terminal in the inverter? 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. I'm asking because I do, in fact, have an equipment grounding conductor from the array connected to the ground terminal in the inverter at a home. I am getting an F08 GFDI fault. 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.
