 CHROMA 11672 Soft Panel Kit for 62000H-S Series Power Supplies  

The model 62000H-S offers optional    through remote digital interface (USB / GPIB / Ethernet / RS232) control. The user can easily program the I-V curve of the 62000H-S as well as the I-V & P-V curves for real-time testing. In addition it will display the MPPT status for the PV inverter.  The Solar Array Simulator is capable of simulating diffe types of standard crystalline, multi-crystalline and thin-film fill factor* parameters to verify the MPPT tracking algorithm mechanism and efficiency.  The user can recall the I-V curve from 62000H-S afterwards for testing and monitoring the MPPT performance of PV inverter with the real-time tracking feature. The softpanel allows the user to set the duration for static MPPT efficiency testing. Each curve test time should be set at between 60s-600s for best MPPT efficiency performance analysis.  The real world weather simulation function allows the user to import real conditions of irradiation and temperature profiles of  a whole day from excel file to the Softpanel in order to simulate the irradiation intensity and temperature level from early morning to nightfall. It can also set the interval time resolution to 1s for I-V curve update rate and enable the user to perform MPPT tracking tests under the simulation of actual weather environments. The softpanel also provides data recording capabilities, which include: voltage, current, power, energy and MPPT efficiency and the corresponding parameter sampling time (1s~10000s) for the recording process. The report can be utilized for R&D design characterization verification, QA verification and production quality control.
