The robust portable battery operated MP-11 I-V Checker enables the operator to perform accurate I-V performance measurements and inspection of PV modules or arrays on site. For direct control of the measurement functions and analyzing measurement results the Main Unit has a key-pad and Graphical LCD display. 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 to measure I-V curves based on the parameters (Vmax, Imax, Pmax, Voc, Isc, FF, Tmod, ηeff) of any PV module types and arrays, also called strings. It is highly ...
