Change in 2023 NEC code around PV arc fault.

They already are. The Solark 15k and EG418k both do everything that you would want a unit to do and are easy to install, not too bad to configure and price efficient. The only thing the 6848 has going for it is the absolutely incredible capacity overhead it has. Basically I see it as a power inverter and nothing more.
And I just saw the announcement at luxpower have integrated with tigo monitoring, this is becoming a One-Stop shop plug and play.

If you were Off-grid, the panels were mounted on the ground, and money was not a factor, which would you purchase? I haven't seen much in the way of Solark 15k tested against a Schneider 6848 but I have seen the Solark 12k against the 6848. Is the different-sized MPPT pv inputs on the 18kpv limiting with the larger panels in the 450W range? I am at a crossroads here...

If money (and space) was not an issue I would get two 6848's over the SolArk or EG4 for reliability. When it comes to flexibility with different operating modes I don't think there is a clear winner yet.

I don't think there's a difference in the 2020 vs. 2023 codes besides wording.

I sometimes like to visualize the hell out of ('merican) legalese to make it more digestible.

2023 NEC Section 690.11 Arc-Fault Circuit Protection (DC) flow chart:


Assume ≥80V DC circuits in metal raceway or underground: Is AFCI required on the DC circuits? See below.
I wonder how section 690.11 applies to "Mobile Homes" and "Park trailers".
My guess it "depends on the AHJ" etc etc.
