SMA SB RS-232-N Module for Remote Comm to PCWrite a review

I use it on my Sunny Boy 2500, and it allows me to do capture data using the freeware Sunny Data program from SMA. It's too bad you can't use the RS-232 interface and the display built into the inverter. With a few more pieces of software I post the data "live" to my website: www.ClassicSolar.com
