SOLAR300N tests the efficiency of a  single-phase and three-phase photovoltaic systems.

Categories: ,

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. HT Italia has solve this problem by creating a remote measuring device SOLAR02 which acquires the values of solar Irradiation [W/m2], panel Temperature [°C] and environmental Temperature [°C] and transfers them onto SOLAR300N, which inserts them onto the same string of power measurements an then elaborates them with the simultaneity required by the law in force.

At the end of calculation, the indication of a positive or negative result of testing appears on the display of SOLAR300N. SOLAR300N is not only a device for testing PV systems, but also a powerful device for a complete analysis of mains quality according to standard EN50160 (harmonic analysis, voltage anomalies, flickers, unbalance, etc.).
