High speed high performance photovoltaic / solar simulation power supply

ITECH high speed high performance photovoltaic / solar simulation power supply, adopting high-speed high-performance high-power DC power supply equipped with SAS1000 solar array simulation software, involves more than 200 models with wide voltage and current range, the output up to 2250V, 2040A. A machine can cover a wide range of application requirements, easy to choose the required models for users. Photovoltaic / solar simulation power supply supports edge time independent set for each mode, has double quadrant current seamless switching function, and supports OVP, OCP, OPP, OTP, Vsense reverse and other protection functions.

ITECH high speed high performance photovoltaic / solar simulation power supply has graphical software interface, users can easily use the software to output, measure, display the maximum power tracking status of photovoltaic inverter in real time and record value. Built-in EN50530 / Sandia and other five kinds of regulatory testing procedures, it is convenient for users to test the static and dynamic MPPT performance of PV inverters and generate reports, so as to compare with competitors' results. Solar simulation power supply also provides the shadow and table mode, the user can enter the 128 ~ 4096 points array to edit any shielded IV curve to achieve dynamic shadow effect and also can store 100 I-V curves under different irradiation and temperature to test the long-term maximum power tracking performance of photovoltaic inverters under different climatic conditions.

Simulate the output characteristics of various solar cell (FILL FACTOR)

Since solar cell utilization is not only related to its internal characteristics, but also related to weather, season, temperature, irradiation, cloud cover, rain and snow and other factors, solar cell has different I-V characteristics in different periods. Therefore, PV inverter must have a strategy to adjust real-time working point of the solar cell to make it always work in the vicinity of the maximum power point, this process is called MPPT. ITECH high speed high performance photovoltaic / solar simulation power supply can be used to directly simulate various real-life solar cell arrays in a laboratory test environment to test the static & dynamic MPPT performance of photovoltaic inverters.

Static & Dynamic MPPT performance test

MPPT tracking performance is a very important specification of PV inverter, PV inverter needs a built-in MPPT mechanism to track real-time maximum output power of solar cell. Therefore, some of the industry's organizations have defined some "standard" test patterns to match all kinds of inverters, which allows inverter manufacturers to test and improve MPPT performance. Build-in MPPT test program of EN50530、SANDIA、NB/T32004、NB/T32004、CGC/GF004, users can set their own Vmp, Pmp, materials and other parameters, test run time and maximum run power percentage, the I-V curve and the real-time trace process are displayed on the screen to verify MPPT performance of the PV inverter, record the data during the whole test and generate report.

Shield I-V curve simulation（Shadow Mode）

ITECH high speed high performance photovoltaic / solar simulation power supply can help users to complete the solar array output simulation under different shadow modes, test and track real-time maximum power and performance test of the PV array. Providing various Module for the user to choose according to different supplier, users can also build their own PV module.  User can define irradiation and temperature parameters of shadow, cell string set, parallel quantity and dynamic shielding the moving direction of the cloud, initialization time, running time and the time interval of cloud moving
