Chroma 62000H-S

The Best Solar Array Simulator

This programmable solar array simulator simulates 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 package. The solar array simulator is highly stable and has a fast transient response design, which is advantageous to MPPT performance evaluation on PV inverter devices.

The 62000H-S Series has a built-in EN50530 and Sandia’s SAS model that can easily program the Voc, Isc, Vmp, and Imp parameters to simulate different solar cell materials’ I-V characteristic outputs with fast response time. Moreover, the TABLE mode can save a 128~4096 point array of user-programmed voltages and currents via a remote interface. It can easily create a shadowed I-V curve, and the I-V PROGRAM mode can save up to 100 I-V curves and dwell time intervals (1-15,000s) in memory. These advantages provide steady repetitive control conditions required for PV Inverter design and verification testing. The solar array simulator is ideal for the following tests:

• Design and verify the maximum power tracking circuit and
  algorithm of PV inverter
• Verify the high/low limit of operating input voltage allowed for
  PV inverter
• Verify the high/low limit of operating input voltage allowed for
  the inverters maximum power point ‘
• Verify the static maximum power point tracking efficiency of
  PV inverter
• Measure and verify the overall efficiency & conversion
  efficiency of PV inverter *
• Verify the maximum power point tracking performance of the inverter for dynamic curves. (EN50530, Sandia, CGC/GF004, CGC/GF035, NB/T 32004 standard)
• Verify the maximum power point tracking performance of the inverter under different time period conditions spanning from morning to nightfall
• Verify the maximum power point tracking mechanism of the inverter for  I-V curve when the solar array is shaded by clouds or trees
• Simulate the I-V curve under the actual environmental temperatures in a burn-in room for inverter burn-in test
