Description

The 62000H-S programmable Solar Array Simulator provides simulation of Voc (open circuit voltage) up to 1000V and Isc (short circuit current) up to 25A. 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, which are both needed for MPPT performance evaluation on PV inverter devices.

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.

IV Curve Simulation

62000H DC Power Supply Solar Soft PanelA 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. The 62000H-S has a built-in 16 bit digital control and precision voltage & current measurement circuits with a voltage accuracy of 0.05%+0.05%FS 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.

Controller Interface

The 62000H Solar Array Simulator is very easy to operate from the front panel keypad or from the remote controller via USB / RS232 / RS485 / APG (standard) and GPIB & Ethernet (optional). Its compact size is good for both benchtop and standard racking.

SOLAR ARRAY IV CURVE SIMULATOR POWER SUPPLY

The Solar Array Simulator can easily program the Voc, Isc, Vmp, and Imp parameters to simulate the different I-V characteristic outputs of various solar cell materials with extremely fast response time. In addition, the TABLE mode is capable of saving a 128 point array of user programmed voltages and currents via a remote interface. It can 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 that are required for PV Inverter design as well as for verification testing. The solar array simulator is ideal for testing the following:

  • Design and verify the maximum power tracking circuit and algorithm of the PV inverter.
  • Verify the high/low limit of operating input voltage allowed for the PV inverter.
  • Verify the high/low limit of operating input voltage allowed for the inverter’s maximum power point.
  • Verify the static maximum power point tracking efficiency of the PV inverter.
  • Measure and verify the overall efficiency & conversion efficiency of PV inverter.(*Requires an extra power meter.)
  • Verify the maximum power point tracking performance of the inverter for dynamic curves. (EN50530, Sandia, CGC/GF004 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 the I-V curve when the solar array is shaded by clouds or trees.
  • Simulate the I-V curve under the actual environmental temperatures within burn-in room to do inverter burn-in testing.

SOLAR ARRAY IV CURVE SIMULATOR SOFTPANEL

The model 62000H-S offers optional graphical user Interface software through remote digital interface (USB / GPIB / Ethernet / RS232) control. The user can easily program the I-V curve of the 62000H-S as well as the I-V & P-V curves for real-time testing. In addition it will display the MPPT status for the PV inverter. Readings and the report function with real-time monitoring using the softpanel are shown left.

SIMULATES DIFFERENT SOLAR CELL MATERIALS IV CHARACTERISTIC FILL FACTOR

The purpose of the PV inverter is to convert the dc voltage (from solar array) to the ac power (utility). The better a PV inverter can adapt to the various irradiation & temperature conditions of sun, the more power that can be fed into the utility grid over time. So, the MPPT performance is a very important factor for PV generation system. The Solar Array Simulator is capable of simulating different types of standard crystalline, multi-crystalline and thin-film fill factor* parameters to verify the MPPT tracking algorithm mechanism and efficiency.

*Fill Factor = (Imp*Vmp)/(Isc*Voc)

STATIC MPPT EFFICIENCY TESTING

The 62000H-S Solar Array Simulator can program the I-V curve through SAS mode and table mode via front panel or softpanel easily and up to 100 I-V curves can be stored in the unit. The user can recall the I-V curve from 62000H-S afterwards for testing and monitoring the MPPT performance of PV inverter with the real-time tracking feature. The softpanel allows the user to set the duration for static MPPT efficiency testing. Each curve test time should be set at between 60s-600s for best MPPT efficiency performance analysis.

DYNAMIC MPPT EFFICIENCY TESTING

The latest test standards EN50530, CGC/GF004 & Sandia have provided a procedure for testing patterns of the dynamic MPPT efficiency of inverters, those standards can accelerate the MPP tracking algorithm mechanism to the optimal for PV inverter manufactures. The advanced Dynamic MPPT Test function complies with EN50530, CGC/GF004, Sandia test regulations and can be controlled via the graphical softpanel by selecting CGC/GF004 or Sandia or EN50530 I-V mathematical expressions and test items. This function simulates the irradiation intensity and temperature change of the I-Vcurve under actual weather variations to test the PV inverter’s dynamic MPPT performance. The GUI will calculate the MPPT performance for analysis after running the test. A test data recording function is integrated into the software where users can edit and control the test parameters to be recorded such as voltage, current, power, watt and MPPT performance along with the sampling interval (1 – 10,000s) and total time length to facilitate the analysis and validation of the PV inverter.

REAL WORLD WEATHER SIMULATOR

The real world weather simulation function allows the user to import real conditions of irradiation and temperature profiles of a whole day from excel file to the Softpanel in order to simulate the irradiation intensity and temperature level from early morning to nightfall. It can also set the interval time resolution to 1s for I-V curve update rate and enable the user to perform MPPT tracking tests under the simulation of actual weather environments.

AUTO RUN FUNCTION OF STATIC & DYNAMIC MPPT TESTING

In order to easily test the static & dynamic MPPT performance of standard EN50530 & Sandia for PV inverter, the SoftPanel has an auto run function, which the user only has to set the Vmin, Vnom, Vmax, Pmax, Stabilization time &Testing period time parameter and testing items of EN50530 & Sandia, then the softpanel can run tests automatically and generate reports after finished.

REPORT FUNCTION

The softpanel also provides data recording capabilities, which include: voltage, current, power, energy and MPPT efficiency and the corresponding parameter sampling time (1s~10000s) for the recording process. The report can be utilized for R&D design characterization verification, QA verification and production quality control.
