here for the sunshine shenanigans
Looks like for residential, we’re still stuck with Tesla as the inverter solution. Hoping we get some other manufacturers in the mix, soon.
I imagine I may have been the subject of some colorful language today. 😅 I don’t see any manuals up yet, so I’d guess we’ll see them tomorrow or later in the week. I’ll get all the details posted on UL3741.com as soon as I get those in my sunny li’l hands.
Intertek has posted the updated Photovoltaic Hazard Control listings for Unirac on their directory, and it includes a few new racking models.
Included in the listing are existing racking models, which are exclusive to flat roof solutions, but newly added to the list are NXT Umount and SolarMount, with callouts for both residential and commercial.
The full list of new addendums:
We don’t know yet what inverters will be listed with these racking systems, or exactly what installation will look like, but it’s safe to assume that we can expect something similar to Ironridge and Chiko’s listings.
Chiko is the only company so far to have listings for a sloped-roof racking that includes commercial inverters, but it sounds like Unirac will be next to the party. This will be immensely helpful for solutions like agriculture, where there’s often large, accessible, sloped roofs that could accommodate roof-mounted inverters.
This is as yet unannounced by Unirac, so the cited documentation in the listing is not available publicly. I imagine we’ll see more details in the coming weeks. Update: Unirac has now officially announced these listings.
