It uses a high quality monocrystalline PV cell laminated with anti-reflective solar glass, so as to have the same spectral and angular response as the plant's modules: this is the figure required to calculate the Performance Ratio and verify actual yield according to \u003cstrong\u003eIEC 61724-1\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eIt is installed \u003cstrong\u003ecoplanar with the modules\u003c\/strong\u003e, on the mounting structure, using the fixing bracket supplied. The output is \u003cstrong\u003edigital RS485 with Modbus RTU protocol compliant with the SunSpec standard\u003c\/strong\u003e, so it connects directly to the data loggers and smart loggers of the main inverter manufacturers. The connection is made with an \u003cstrong\u003e8-pin IP67 M12 connector\u003c\/strong\u003e on a 50 cm UV-resistant cable; the power supply is \u003cstrong\u003e9–30 V DC\u003c\/strong\u003e with protection against polarity reversal and short circuit. The body is made of \u003cstrong\u003ealuminium with UV-resistant E.V.A. encapsulation\u003c\/strong\u003e. The sensor also includes temperature measurement and can be combined with the Temmeter module temperature probe and the anemometer of the same family.\u003c\/p\u003e\u003ch3\u003eKey
