A variable load is applied across the four wires in order to get a variety of current and voltage measurements for the device under test. Exactly what current and voltage is unknown until tested, which is why there is some iteration needed.
A solar photovoltaic (PV) system is required to be rigorously tested as part of the commissioning process and periodically throughout its subsequent lifespan. This is to test both the quality of the installation and the quality of its performance.
