SOLAR300N tests the efficiency of a single-phase and three-phase photovoltaic systems. For this kind of tests, it is necessary to guarantee simultaneity between power measurements carried out at the inverter and irradiation and temperature measurements carried out on the photovoltaic panels.

At the end of calculation, the indication of a positive or negative result of testing appears on the display of SOLAR300N. Beside measuring and logging the efficiency of PV systems, SOLAR300N is also a powerful power quality analyzer to perform analysis according to EN50160 (harmonics, voltage anomalies, flicker, voltage unbalance, etc.). While used as a power quality analyzer, flexible clamps HTFLEX33e can be used, while in PV analyzing flexible clamps cannot be used.
