Portable IV Tester (YH-BXIV)
The portable IV tester is a standard string-based power tester that can accurately complete power detection and IV curve testing for individual modules and strings, standard power conversion efficiency under STC, and PV power plant system PR value testing. The Chinese version of the system is easy to operate, portable, and is equipped with a high-precision irradiance meter and temperature sensor. Its fast and accurate testing efficiency makes it the preferred model for third-party testing agencies and power plant operations and maintenance.
The portable IV tester YH-BXIV has a localized configuration with a Chinese interface and one-click testing mode. It is simple to operate and carry, with after-sales efficiency and maintenance costs far exceeding those of imported configurations.
The YH-BXIV adopts an integrated packaging machine body design, is easy to operate with clear Chinese and English interface descriptions, one-click data export, and a testing speed of 10 seconds for individual modules/strings. The device has a built-in database of multiple photovoltaic panel specifications, allowing for one-click import to reduce the hassle of switching between different specifications during testing.
Technical Features:
- The portable IV tester uses wireless connection between the main unit and the probe, providing up to 100 meters of wireless communication range, making testing more convenient.
- Equipped with a patented probe box and temperature probe mounting bracket for easy and quick probe installation on solar panels.
- Unique barcode scanning function for intelligent component identification.
- High-brightness, sunlight-visible color LCD display with touch screen and keyboard operation, featuring rich peripheral interfaces for an exceptional user experience. The internal memory of the portable IV tester can store over 2,000 test waveforms and has an SD card slot for memory expansion.
- Utilizes a WINCE graphical system with multilingual options and user-friendly menu design for easy mastery of the instrument's functions.
- Includes user analysis software, allowing users to copy data stored in the main unit to a PC via USB for analysis and printing.
- Supports outdoor low-light IV characteristic testing and provides standard STC condition corrections. If required, the portable IV tester can offer metrology services and issue certification.
- Built-in solar cell module correction model database covering products from most manufacturers, offering references for conversion comparison and providing comprehensive parameter settings for users to manually add testing correction models.
- The internal design includes high-voltage isolation power, ensuring reliable safety. The tester supports a wide voltage testing range, with a maximum open-circuit voltage of 1500V and testing capabilities for PV arrays up to 30kW.
- Automatic range switching with over-voltage and over-current protection, plus a configurable continuous testing function.
- Equipped with a large-capacity, replaceable lithium-ion battery for ample testing power.
- Provides environmental monitoring functions, including temperature, solar panel temperature, and irradiance detection, with optional irradiance metrology certification.
- Measurable parameters: I-V curve, P-V curve, short-circuit current, open-circuit voltage, peak power, peak power point voltage and current, constant voltage point current, fill factor, conversion efficiency, series resistance, parallel resistance, solar cell temperature, environmental temperature, and irradiance.
- The PV32 portable IV tester has a unique component power generation test function that complies with the IEC61853 regulations for component certification testing adopted by the EU or for local sunlight resource monitoring. The tester also provides up to 400 points of high-resolution testing and Ethernet monitoring compatible with the Modbus/tcp protocol, meeting scientific research needs.
- The portable IV tester has a unique compensation design that supports outdoor verification of photovoltaic cells, suitable for outdoor performance testing of photovoltaic cells still in the experimental stage.
Performance Advantages:
Solar panel cracks can affect the entire panel. However, through IV characteristic testing, the open-circuit voltage and short-circuit current losses can be analyzed using software, showing a loss of 10.9% and 53.7%, respectively, with a noticeable change in the power loss curve, which reaches 67.8% and STC-63.5%. The portable IV tester helps assist EL detection to determine whether the component can continue to be used.
STC Nominal Parameter Conversion Testing: The IV test matches over 95% of current photovoltaic cell specifications, quickly switches between different specifications, and automatically calculates the module's current power generation efficiency and conversion rate, helping users understand the real parameters of the components more accurately.
Compliance Standards:
- IEC 61215-2005: Ground-mounted crystalline silicon photovoltaic modules – Design qualification and type approval
- IEC 61646-2008: Design and qualification standards for thin-film photovoltaic modules
- CGC/GF003.1:2009: Technical Specifications for Grid-Connected Photovoltaic Power Generation System Engineering Acceptance, Part 1: Electrical Equipment
- GB4793.1-2007/IEC 60010-1: Safety requirements for electrical equipment for testing, control, and laboratory use
- IEC 60904-2: 2007 Standard for solar cell requirements
- IEC 60891-2009: Temperature and irradiance correction methods for I-V characteristics of photovoltaic devices
- IEC 61853-2011: Photovoltaic device performance testing and energy rating
- CE and ROHS certification
- Verified by the China National Institute of Metrology, with voltage and current test accuracy exceeding 0.2%, meeting and exceeding product specifications.
Specifications:
- (1) Tested at 25°C under standard testing conditions
- (2) Conversion to STC under the most accurate power condition is measured under stable irradiance ≥ 700W/m², with an AM1.5 spectrum. In laboratory conditions, this accuracy is generally within 2%. On-site testing should be performed under stable sunlight conditions with the irradiance probe installed reliably to avoid conversion errors caused by irradiance and temperature deviations.
