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!

Good afternoon,
my name is Andrea Costantini and I’m working on this gateway for a similar solar-powered installation.
I’ve seen this topic but the link to DIY_Gateway_Battery.pdf returns a bad result.
Is it possible to update the link please?
Many thanks and best regards¨
