The latest programmable solar array simulator power supply 62000H-S Series released by Chroma provide 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, which are both advantageos to MPPT performance evaluation on PV inverter devices.

The 62000H-S Series has 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 is 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. The 62000H-S Series has a built-in 16 bit digital control and precision voltage & current measurement circuits with a voltage accuracy of 0.05% + 0.05% F.S. and a current accuracy of 0.1% + 0.1% F.S. It is ideal for real time MPPT analysis and tracking monitoring for PV inverters through our softpanel.

The user can also enable the data recording function on the softpanel during the static MPPT performance test. When high power solar array simulation is required, it is common to connect two or more power modules in parallel. The 62000HS Series with a current range up to 30A and a voltage range up to 1800V offers a high power density envelope maximum of 18kW in a 3U package. It can easily parallel up to 16 units in a Master/Slave configuration to provide 288kW with current sharing and synchronized control signals for commercial utility PV inverter (10kW~100kW) testing.

The 62000H-S Series supplies have a smart Master/Slave control mode that makes the parallel operation fast and simple. In this mode, the master scales values and downloads data to slave units so that the programming is as simple as using a standalone unit. The 62000H-S Series DC power supplies are very easy to operate from the front panel keypad or from the remote controller via Ethernet/USB/RS232/RS485/GPIB/APG. Its compact size (3U) makes it ideal for both benchtop and standard racking.
