Finally going solar. I have a question about Enphase microinverters and Powerwall compatibility

Did you click on the link in the post?
I just tried to type it in the address bar without that http:// and doesn't work, then a couple of other variants, nothing.
The link still works though.
Then tried the address bar again, carefully typing in what is in that link, it works.

Without the http:// browsers typically go to Google search, which knows nothing about IP addresses on your home network. So that won't work. With the https:// browsers typically go straight to DNS, starting with your local router which, hopefully, has logged the envoy with it's server name along with the IP address the router assigned via DHCP to it.
