Ok took awhile but I now have the complete answer.
1st) u must check your county ordinance. Most are available online but you can talk to the code enforcement office.
Mine requires everything to be UL Listed. Btw ETL is not enough nor is UL certified. UL Listed will have the UL emblem.
Big diff between 458 and 1741. UL458 is mobile like an RV, boat, etc... UL1741 is for stationary like home, cabin, shed, etc...
As far as Will: my best guess is he is paid to do videos on solar products. I say this cuz he did a video of his home system. Curious, I looked up his items and yep, all were UL Listed. And specifically his home inverter was UL1741.
All products except batteries can be UL Listed. Even on the cabling it will say UL (barely legible).
Once again, it all comes down to your county ordinance requirement. And yes, UL Listed does cost more.
Keep in mind, UL Listed is the safest. I ended up with UL Sunpower brand panels cuz they have the UL stamp on each one.
And btw, my county ordinance also required anti-reflective coating and minimum 2400pa wind restriction.
Theres also codes about roof and ground mounting.
Good luck. Took me months to research and find out all of this, much less, the items. I found the cheapest UL Listed 1741 inverter was AIMS.
