So it seems my installer has to enable manager mode for me, and it is (or was at some point) a $249 one time fee to add it.
I didn't pay for it, possibly it's because I took the
online Enphase classes and look like an installer? A call to tech support might fix it.
What error do you get when you enter the URL below (change
siteID to your site's ID and get rid of the space after
https):
https ://enlighten.enphaseenergy.com/systems/
siteID/arrays/
The URL domain (i.e., enlighten.enphaseenergy.com) is the same for all three, what's different is the "New view" is /
web, the "classic" view is "/
pv", the "manager" view is "/
systems". For example the classic view is https ://enlighten.enphaseenergy.com/
pv/
siteID
The manager view will let you traverse to the "dashboard" view (which is a different subdomain) or the "new view", the "new view" will let you go to the "classic" view or the manager view (click the 3 bars in the upper right and it's the top entry).
