Hi All, I am about to install a solar system with a Fronius IG 15 inverter, all the systems I have done before have had MC4 plugs on, so Voc and Isc testing is quite straight forward, but this inverter is hard wired into a terminal block inside the inverter! How do I link the cables for the Isc test, and do I do the Voc in the isolater, while its connected into the terminals????? any help would be gratefully recieved, many thanks!
