Meanwhile, i need to find a small FTP c-library to use to push the inverter data. I tried using mydns.com to get a dynamic domain to the public IP address of the network hosting my systems, but it just gets to the ISP's boundary router; those clever folks stop all unsolicated inbound traffic, so rather than hacking their system, I'll just FTP push the collected data to my cruzio.com account and have a listener file I can send commands. It's crude but works. If anyone has a better (windows based, sorry) solution, let me know.
More when I get there.
