The latest programmable solar array simulator power supply 62000H-S Series, released by Chroma, provides simulation of Voc (open circuit voltage) up to 1800V and Isc (short circuit current) up to 30A. The 62000H-S provides an industry leading power density in a small 3U high package.
The solar array simulator is highly stable and has a fast transient response design, both of which are advantageous to MPPT performance evaluation on PV inverter devices.
The 62000H-S Series have many unique advantages including high speed & precision digitizing measurement circuits with a 100kHz A/D, 25kHz D/A controlled I-V curve and a digital filter mechanism.
It can simulate an I-V curve accurately and response the mains ripple effect from the PV inverter. In addition, the built-in EN50530/Sandia SAS I-V model in the standalone unit can easily program the Voc, Isc, Vmp, and Imp parameters for I-V curve simulation, without a PC controller.
The real solar array is influenced by various weather conditions such as irradiation, temperature, rain and shade by trees or clouds, which will affect the I-V curve output. The 62000H-S Series are capable of storing up to 100 I-V curves into the simulator memory, with a programmed time interval range of 1-15,000 seconds.
It can simulate the I-V curve from the early morning to nightfall for PV inverter testing or dynamic I-V curve transient testing.
