With the extension boxes, the PV Master 10 can easily be adapted to a multi-channel IV curve measuring device. As can be seen in the connection diagrams on the left and right, it is very easy to connect the extension box and the PV Master, then only the strings need to be connected and the measurement can begin.
There are three verisons of the extensionbox available with 4, 8 and 20 string inputs. Please feel free to check the video below on how to use the extension box with the PV Master 10
