I-V Curve Tracer [PV Analyzer Gamma 600/1000]
High-precision IV curve measurement device. Detailed measurement settings and automatic measurements can be performed without a PC. Ideal for the development and research of solar cells, such as outdoor exposure tests. [Demo unit available for loan◎]
We have adopted an electronic load method to achieve high-performance I-V curve measurement. Based on customer requirements, we will configure a solar cell evaluation system centered around this device. We can also propose systems such as measurement systems in open state and grid-connected measurement systems using power conditioners. Of course, it can also be used for maintenance purposes. ◆ Variable sweep direction: short circuit → open circuit, open circuit → short circuit, etc. ◆ Variable sweep time: 150[ms] to 1000[ms] ◆ I-V curves can be checked on-site using a high-resolution color monitor ◆ Measurement of special solar cells (CPV) from a single unit is possible ◆ Clear graph display through 1024-point measurement * For more details, please download the PDF or feel free to contact us. * Demo units are also available for loan, so please get in touch.

Our new I-V curve tracer can measure "high-efficiency solar cells" such as N-type, half-cut cells, and N-type back contact.
In recent years, there have been reports of cases where high-efficiency solar cells (such as N-type and half-cut cells) cannot measure I-V curves using competitor products or the old Epsilon 1000 (PVA14300). However, measurement is possible with the current Epsilon 1000 (PVA14300R) and Epsilon 1500 (PVA18340). Both the current and old models of Epsilon have a built-in overcurrent detection circuit, which prevents equipment failure by cutting off the current and stopping I-V curve measurement if the measurable current exceeds 30 [A] (when overcurrent is detected). High-efficiency solar cells tend to have a large inrush current flowing into the Epsilon, leading to a higher frequency of measurement stoppages due to overcurrent detection with the old Epsilon. Even if the catalog value of the solar cell is around 15 [A], the actual output current can momentarily exceed 30 [A] significantly. The current Epsilon is equipped with an inrush current prevention circuit that performs gradual short-circuit processing. This suppresses the occurrence of overcurrent during short circuits, making measurement possible even when the capacitive component of the PV is large. Measurement is also possible with the Gamma series and Delta.

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.
