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.

We have published a technical column titled "How to Choose Batteries for Cold Weather and Outdoor Use" (A4, 4 pages, with illustrations). Have you ever felt that "the battery drained quickly" while outdoors in winter? It may not necessarily mean that the electricity inside is depleted; it could be that the battery has become difficult to remove due to the cold. This document organizes what happens inside a battery when it cools down and summarizes the items to check when selecting a battery based on temperature. [Contents] - What happens inside a battery when it cools down - Confirming "usable temperature" divided into discharge, charge, and storage - Things to check at low temperatures by type (quick reference table) - Considering the placement (devices placed outdoors / devices used in cold regions / locations that become unmanned at night) - Common mistakes and checklist items before selection, how to read specifications This document organizes general considerations by type. The usable temperature and the amount that can be extracted vary by product. If you let us know the temperature in the coldest situation, whether charging is available, and the required current output, we can assist you with potential product recommendations.

The Hino Smart Cabinet provided by Nichinichi Shimizu Machinery Co., Ltd. is a material management solution that allows for the management of factory tools and consumables like a vending machine. This system automates inventory management and ordering processes, preventing the risk of production stoppages due to stockouts and significantly reducing the burden of inventory tasks. The cabinet comes in various types, such as drawer-type and spiral-type, allowing for the proper storage of drills, measuring instruments, protective gear, and more according to their intended use. Furthermore, the history management function through user authentication accurately tracks "who took out what and when," contributing to loss prevention and cost reduction. Operating 24/7 with no maintenance required, it is introduced as an efficient tool to promote the digital transformation (DX) of factories.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can cause changes in the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

When it comes to environmental measures on site, many may think of waste reduction and energy conservation. However, there are also issues that can be addressed by reconsidering the materials used daily, such as summer glare, metallic sounds during vehicle operation, burdens from material transportation, and consideration for the surrounding landscape. Hyper CLT mats are wooden lightweight mats made from CLT (Cross Laminated Timber) that is laminated with the wood fibers crossing each other. They can be considered for use in temporary roads, access routes, material yards, heavy machinery work areas, and worker pathways. Wooden mats are characterized by their ability to reduce glare and radiant heat compared to steel plates, and they are also easier to manage in terms of metallic sounds during vehicle operation. The 5×10 version weighs about 230 kg, and the 5×20 version weighs about 460 kg, making them relatively lightweight, which can lead to more efficient relocation and transportation depending on site conditions. Additionally, by utilizing wood, they can be proposed as part of CO₂ fixation and environmental consideration efforts. Hyper CLT mats are registered technologies with the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) under the NETIS system. The NETIS registration number is "TH-250021-A". They can also be incorporated into the use of new technologies and creative ideas in public works. Wooden mats, NETIS, civil engineering, CLT, wooden lightweight mats. Environmental measures on site can begin not only with large equipment but also by changing the materials at our feet.
