Connecting Solar Assistant to an inverter.
I used this to connect my Solar Assistant, to a Growatt inverter. It worked instantly, and was exactly what was required. I stupidly tried a different one first that didn't work, but this one works perfectly.

Works out of the box
I brought this item and used with Windows 11 & Modscan. Worked straight out of the box with no manual driver configuration necessary. Used to read values from a Carlo Gavazzi EM21 electricity meter. Very good value for money
