Product description

PVA Series Programmable Solar Cell Analog Power Supply
PVA series solar cell analog power supply adopts DSP digital control technology. Power inverter adopts new soft switch and low loss rectification technology. The power efficiency is over 95% in the wide voltage power output power range, with low ripple, high power density, dynamic With good characteristics and advanced process, it can simulate the condition of various solar panels (such as thin film batteries) under different weather conditions based on solar panel information.

The products are widely used in the production, detection and aging of photovoltaic grid-connected inverters, simulating the tracking of maximum power MPPT and various performances. The functional relationship model of the built-in solar cell characteristics of the single unit allows the user to simply set the solar cell single or multiple IV (Voc/Isc) data in the machine panel and save it. The power supply can output the simulated solar cell array IV curve for different periods of time. The transformer tests its static or dynamic MPPT performance. The product design power ranges from 10 kW to 200 kW, and the voltage range is from 52V to 1000V, which can be arbitrarily combined to 1 MW.

Product performance characteristics:

• Adapt to a variety of photovoltaic panel types: single crystal, polycrystalline, amorphous, etc.
• Output mode MTTP mode and constant voltage, constant current, constant power output mode.
• Basic functions for universal test DC power supply programming.
• Automatic programming to control I-V curve output
(You can automatically program any number of curves and run by time)
• Simulate different types of solar array I-V curves
• Simulate I-V curves at different temperatures and light intensities
• Simulated PV array local shadow occlusion I-V curve
• Simulated scaling of I-V curves under full-day sunshine
• Static and dynamic MPPT performance test
• Simulate all-day cumulative energy metering
• High output current and voltage accuracy
• The conversion efficiency is as high as 95% or more, and the total harmonic THD is less than 5%, which has less harmonic pollution to the power grid.
• High degree of intelligence: friendly man-machine interface, LCD large screen display, curve, programming at a glance, touch operation, automatic data storage. The output can be configured with USB / RS232 / RS485 control interface, which can be operated by the local machine or by the host computer software.
