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 Best Solar Array Simulator
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
*Requires an extra power meter.
High Speed & Precision Digitizing Measurement
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 clear the mains ripple effect from the PV inverter. In addition, the built-in 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 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.
IV Curve Simulation
A real solar array is influenced by various weather conditions like irradiation, temperature, rain, and shade by trees or clouds, which will affect the I-V curve output. The 62000H-S 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.
