Multi-measuring instrument for solar cell inspection [Bypass diode checker]
BDC15310-N
【Instant inspection of bypass circuit】0.1[A] voltage measurement, voltage, BPD, and cluster integrated measurement, tester with voltage logging function【Demo unit available for loan】
This product can inspect the presence of open/short circuit failures in the bypass diodes within solar cell modules. Since measurements can be taken at the PV string level, such as in junction boxes, inspections can be conducted efficiently and safely without having to climb onto the roof. 【Commitment to Safety】 Measurements taken during the day can potentially damage solar cells, so our company has designed the product with safety in mind, allowing for short, high-speed measurements limited to low sunlight hours in the morning and evening, or at night. ■ High-speed measurement (approximately 1 second from measurement start to result display) ■ Capable of measuring and determining faults from a single module to the string level (supports strings up to 1000[V] / no voltage limit for nighttime measurements) ■ Two inspection modes: morning/evening mode and night mode for safe and reliable inspections ■ 0.1[A] voltage measurement selectable (breeder measurement) → confirmation of cluster faults ■ Bulk measurement mode for voltage, BPD, and clusters available ■ Equipped with tester function (voltage measurement) ■ Voltage logging function allows for measurement of ground-to-ground voltage → confirmation of safety * For details, please download the catalog or feel free to contact us. * Demo units are also available for loan, so please get in touch.

basic information
◆Why is it necessary to inspect bypass diodes? → The bypass circuit is a safety feature, similar to airbags or seatbelts in a car. While general power generation monitoring cannot determine its health, it is an important function. A bypass diode checker is a measurement tool for solar power maintenance that can assess the condition at the junction box.

Company information
Since the time of the Sunshine Project at the current Ministry of Economy, Trade and Industry, we have developed simulated power sources, measuring instruments, power conditioners, and more, in response to requests from organizations such as the National Institute of Advanced Industrial Science and Technology, the Central Research Institute of Electric Power Industry, and Tokyo University of Agriculture and Technology. Based on these achievements, we have commercialized our products and expanded sales to various research institutes and manufacturers, proudly positioning ourselves as a niche leader in this field. We specialize in the development of products and systems that combine hardware and software, including simulated power sources such as solar cells and storage batteries, load devices necessary for grid connection testing, and testing systems that operate these components collectively. We also have extensive experience in solar cell measurement, and our I-V curve tracer is widely used not only for the maintenance of solar power plants but also for research and development purposes at manufacturers, research institutions, and universities. We have numerous delivery records of automated measurement systems that incorporate measuring instruments and load devices. Development of power electronics equipment that combines analog and digital technologies, development of control software using DSP, and construction of PV measurement systems are among the services we offer, tailored to meet our customers' needs.
