I have two inverters with data modules. Are they meant to be wired from one to the next and then to the modem or does each need a homerun?

Rum,

No need for separate runs. You connect them in series "daisy chain" fashion.

Execerpt from SMA:

  • Plug-and-play installation, with no wire terminations, is just like plugging a computer into a router/switch
  • Automatic configuration and setup, DHCP, Portal Setup Assistant
  • Automatic product updates ensure that device firmware is always up to date  
  • Star, ring or daisy-chain wiring allowed, just like a LAN
  • Limit of four devices per plant on Sunny Portal (aimed at residential and small commercial  PV systems)

Good luck!
