Setup for RAK7249 solar installation

Hi, I’m setting up a remote install for my RAK7249, and am using a 12v 100W panel, solar regulator, 70ah battery. The regulator will feed into a Tycon 12-48 poe adapter. The gateway will connect via lte to the ttn. Will this connection method work ok, or do I need to connect it via 12v through the external battery connection? I already have the backup battery installed and working inside the enclosure. Thanks!

This may be what you need!
