Good day I would be surprised if it can be used to measure the production of a PV system. The SEM5000 measures the energy consumed by a device at a 230V AC connection. In the PV system, direct current is generated and its voltage is measured at the output of the panels. Converting the SEM5000 will probably be a bigger challenge. Usually, the inverters connected to the PV system provide the information.
Good day I think it should be possible with a little tinkering that is why I ordered it as soon as I have it and have tinkered with the endsprechebde cables I will post the result Hit rein in principle you would have to connect the plus cable from the panel and then the cable to the socket or load
