Nippon Kernel System CO., LTD. List of Products and Services

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.

The "Epsilon 1500V" is an I-V curve tracer designed for the maintenance of high-voltage solar power generation systems. Building on the features of the PV Analyzer "Epsilon 400/1000," it achieves 1500[V] measurement. 【Features】 ■ Short measurement time (approximately 1 second until result display; less affected by sudden changes in sunlight or shadows) ■ Simple operability (no prior settings required; measurement can be done with one button) ■ By connecting this device and the measurement unit (CMU12281, sold separately) to a PC simultaneously, synchronization of I-V curves with solar radiation and temperature data is possible (using the included software) ■ Uses MC4 connectors for measurement connections, ensuring reliable and safe measurements ■ Equipped with a voltage tester function, capable of measuring voltages up to 1500[V] at all times *For more details, please download the PDF or feel free to contact us.

The "Epsilon 1500" is an I-V curve tracer that supports a voltage range of 1500V, suitable for large industrial solar power generation systems. It is an I-V curve tracer for solar cell strings compatible with 1500V/30A. The functions have been significantly renewed from conventional models. It can store up to 9999 data points in internal memory, displays results in about 1 second, and allows for short-term measurements that are less affected by sudden changes in sunlight or shading. 【Features】 - Capable of measuring 1500[V] and 30[A] (can also measure ultra-high output modules such as parallel strings and bifacial modules) - Added a Japanese mode to the operation guide (English is also selectable) - Equipped with reverse connection detection for safe operation (misuse detection) - Uses MC4 connectors for measurement connections, ensuring reliable and safe measurements - Has a voltage tester function, allowing for continuous voltage measurement up to 1500[V] - Internal data storage capacity of 9999 points, suitable for large-scale power plants.

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.

The "Epsilon 400" is an IV curve tracer that supports the voltage range of 400V, which is common for many residential solar power generation systems. It has been newly renewed from the old model PVA12280! Compact and lightweight, it features simple operability and beautiful displays on a color LCD. It can store up to 9999 data points in internal memory, and it allows for approximately 1-second result display, enabling short-term measurements that are less affected by sudden changes in sunlight or shadows. 【Features】 ■ Capable of measuring 400[V] and 30[A] ■ Equipped with an automatic measurement function (manual/automatic selection available) ■ Japanese mode added to the operation guide (English also selectable) ■ Safe operation with reverse connection detection function (misuse detection) ■ Internal data storage capacity of 9999 points, suitable for large-scale power plants ■ Reliable and smooth graph display through 1024-point measurements ■ Linear sweep within 200[ms], with results displayed in about 1 second * For more details, please refer to the PDF document or feel free to contact us. * Demo units are also available for loan, so please get in touch.

In addition to measuring the power generation quadrant characteristics of solar cells, measuring the reverse voltage quadrant characteristics allows for accurate short-circuit current (Isc) measurements and also enables the measurement of bypass diode characteristics within the solar cells. We will configure a solar cell evaluation system centered around this device to meet customer requirements. We can also propose systems such as measurement systems in an open state and grid-connected measurement systems using power conditioners. ◆ The electronic load and reverse voltage application function allow for I-V curve checks in both the power generation quadrant and the reverse voltage quadrant. ◆ The sweep direction is variable: short-circuit to open-circuit, open-circuit to short-circuit, etc. ◆ The sweep time is variable: 150 [ms] to 1000 [ms]. ◆ I-V curves can be checked on-site using a high-resolution color monitor. ◆ Measurements can be taken from a single special solar cell (CPV). ◆ Clear graph displays are achieved through 1024-point measurements. * 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.
