The innovative accessory MPP300, used together with SOLAR300N or SOLAR I-V, allows measuring and recording the main parameters which characterise single-phase and three-phase, single-string and multi-string (up to three strings) photovoltaic systems. MPP300 is perfect for use in systems with three-MPPT three-phase inverter and in three-phase systems provided with three single-phase inverters. MPP300 is provided with a practical anti-shock “field” case, lightweight and small in size. The front panel carries the LEDs for operating information and the DC and AC inputs for upstream and downstream connection of the inverter(s). MPP300 interfaces with SOLAR300N via USB connection and SOLAR I-V via wireless connection. SOLAR300N and SOLAR I-V are used for MPP300 settings, to start/stop recording electrical and environmental parameters and to enable the download of the recorded values. The distance between the photovoltaic modules and the inverter is often considerable, and this forces the operator to carry out measurements in different places at the same time. Therefore, it would be necessary to lay long connection cables between the environmental probes and the instrument. These cables could hamper the operator’s movements, be a hindrance, etc. This kind of connection is therefore not acceptable. In case of photovoltaic installations on buildings, the so-called photovoltaic roofs, in addition to the problem of the distance between modules and inverter, the presence of floors, of reinforced concrete or metal structures, etc. must be taken into consideration. These structures would make a possible (wireless) radio connection between the environmental probes and the instrument impossible, because of signal attenuation. In order to avoid the above-mentioned problems and to carry out measurements with the necessary contemporaneity, MPP300 is synchronized with the remote unit SOLAR-02 (provided as standard accessory of master instrument SOLAR300N or SOLAR I-V).
