MP-11 I-V Checker:

The robust, battery-powered MP-11 I-V Checker allows the operator to perform accurate I-V performance measurements and inspection of PV modules or arrays on-site. The main unit has a keypad and graphic LCD display to directly control the measurement functions and analyze measurement results. The MP-11 offers an all-in-one measurement solution to make PV module testing very easy; hence, all required accessories, like the radiation sensor, temperature sensors, cables, and PC software for control and extended data analysis, are included.

The MP-11 I-V Checker is capable of measuring I-V curves based on the parameters (Vmax, Imax, Pmax, Voc, Isc, FF, Tmod, eff) of any PV module type and arrays, also called strings. It is highly suitable during PV module installation, for the routine inspection of energy yield, tracing module performance and potential defects, and general maintenance checks. The MP-11 can be used for almost any module type as long as the output fits in the range (10–1000V, 100mA–30A, and 10W–18 kW).

The Main Unit can measure, display, and analyze data; all functions can be accessed through the front panel keypad. Up to 300 I-V curves can be stored on board, which is sufficient for one day. Additionally, extensive data analysis, data storage, and data format conversion to a.CSV file format can be done using a PC with the MP-11 control software. The I-V curve measurement data displayed on the main unit are automatically converted into STC values, known as Standard Test Conditions (STC), which comply with the IEC 60981 and JIS C8914 Standards. This way, measurement values converted to STC values can be better quantitatively compared when obtained under different environmental or atmospheric conditions (global radiation, temperature) or between different modules.
