This always makes me a little nervous. Nearly 800 Volts DC coming from 120 panels. This solar controller, from Electro Industries / GaugeTech, has a web management element to allow you to look at historical power generation data. Also has a WiFi antenna to allow you to read data without internet access. Cool stuff.
