In recent years, with the intensification of the energy crisis, renewable energy represented by solar energy and wind power has developed rapidly. ITECH solar test solutions can test the performance of solar cell, PV inverter,Photovoltaic controller(DC-DC).The maximum output voltage and power of ITECH high performance power supply is up to 2250V/1152kW. If equipped with PV simulation program, it can test MPPT compliance with EN50530/SANDIA/NB-T32004/CGC-GF004/CGC-GF035. Also it can simulate IV-curve under different temperature and irradiation. ITECH electronic load with high speed sampling rate (50KHz) is well used to test solar panel and coomponents. 24hrs I-V curve features can be fully verified and the data can be recorded and saved for further analysis.
