We will exhibit at the Solar Summit 2022 ONLINE.

Short-term measurements that display results in about 1 second are possible! Ideal for completion inspections and regular inspections of power generation systems! Available for both sale and rental. *Catalog available.

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.

Automatically detects the occurrence of "solar cell malfunctions" and "DC ground fault incidents" that lead to fire accidents in solar power generation systems, serving as a safety net!

In solar power generation systems, there is a risk of fire accidents caused by factors such as leakage current and failures of bypass diodes in solar cells. To detect these issues, manual inspection work using devices like megohmmeters and bypass diode testing equipment is necessary. However, this device automatically performs these inspection tasks. It captures changes in conditions that are difficult to detect through monitoring measurement values via power conditioners, significantly contributing to the safe operation of solar power generation systems and the maintenance of power generation capacity. Furthermore, it is an unprecedented remote monitoring device capable of detecting cable theft (disconnection) on the DC side. ◆ Measurement of insulation resistance of solar cell strings (DC ground fault detection and ground fault location identification) ◆ Measurement of bypass routes ◆ Measurement of blocking diodes (reverse current prevention diodes) ◆ Measurement of operating voltage of solar cell strings

We will reduce the time and cost associated with the maintenance of solar power generation systems!

It is possible to conduct inspections in accordance with the JPEA/JEMA guidelines. Additionally, it supports original inspections by allowing you to freely select inspection items. On-site, work assistance and measurement data are saved using a tablet PC, while in the office, management software is used to manage customer information, inspection results, and report creation. This software provides total support for PV maintenance from the field to the office, reducing costs and time. ◆ Paperless for a tidy workplace! ◆ On-site work is light and quick! ◆ Report creation time is significantly reduced! ◆ Managing inspection data is easy!

Regardless of differences in evaluators or experience, we have achieved consistent judgments!

"I-V Curve AI for Epsilon" is software that enables the judgment of I-V curves (IV curves), which has previously been left to the subjectivity of evaluators, to be performed using machine learning. This allows for consistent judgments regardless of differences in evaluators or their experience. The "PC software (Learning and Judgment)" reads measurement data and updates the learning data. Based on the learning data, it can automatically classify and distinguish I-V curves into multiple types. Additionally, the "Android software (Measurement and Judgment)" connects to the Epsilon device via Wi-Fi for remote measurement. It displays the judgment results along with the measurement results. [Features of the Android Software (Measurement and Judgment)] ■ Measurement - Remote measurement via Wi-Fi connection to the Epsilon device ■ Judgment - Displays judgment results along with measurement results *For more details, please refer to the PDF materials or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
