Established in the grid-connected photovoltaic power generation system, the most important two parts of this system are photovoltaic array and photovoltaic inverters, so the performance of photovoltaic components and photovoltaic inverters determines the long-term power generation investment efficiency of this system. The system establishes a long-term climate illuminance & temperature change under the actual establishment of the regional operation. At present, there is a tendency to establish a technical requirements for establishing actual climate operating conditions in a specific period, testing the DC power generation of photovoltaic array and the dynamics of photovoltaic inverters. Maximum power point tracking efficiency. On May 31, 2010, the latest EN50530: 2010 test standard announced in Europe, this standard is a test program for the total efficiency and dynamic maximum power point tracking efficiency test of the grid-connected photovoltaic inverter, such as low illumination 10% change to The intensity of 50% strength change, and the medium grading 30% changed to a high degree of 100% strength change.
Qimao Electronics Latest Solar Battery Array IV Simulation Power Supply, Model 62150H-1000S Provides an open circuit voltage (VOC) of the highest simulation solar cell array to 1000V and short-circuit current (ISC) up to 3U high power module, maximum power can reach 450KW / 1000V / 450A. It has an output I-V curve that responds to fast design to simulate the solar cell, which can be applied to the maximum power tracking (MPPT) performance test of photovoltaic inverters.

The latest Dynamic MPPT TEST features will comply with the Sandia & EN50530 test specification, and users can choose Sandia or EN50530 IV mathematical formula and test items by Dynamic Mppt Test feature in the graphical virtual instrument panel software. This can be simulated Illumination and temperature change IV curve test photovoltaic MPPT tracking efficiency, users can simply edit dynamic IV curves to change the time and temperature change time of low illumination changes to high illumination, and set to perform repetition cycles, when testing After execution, this GUI will automatically calculate the MPPT performance to analyze the user, this software will provide the test data recording function, allow the user to edit the measurement parameters to record, such as voltage, current, power, wattage and MPPT efficiency, The sampling time interval (1 - 10,000S) and total length of time can be edited, which will facilitate the analysis to verify the photovoltaic inverter.

In addition, the user can use the Table mode to edit a variety of IV curves. After the IV curve data established by it is exchanged to the single-machine, the SoftPanel, the single-machine voltage and current array of up to 128 points per IV curve. composition. The user can make the user to establish and store 100 curves, which can easily edit the various I-V curves, such as a shadow-shielded I-V curve, which can test the photovoltaic inverter in the shielded I-V curve tracking efficiency.
