Nippon Kernel System CO., LTD. Company Overview

Leave the measurement, research, and testing of renewable energy to us - Development/sales of solar cell measurement equipment, simulated power supplies, and system proposals.

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.

Business Activities

- Development of power conditioner and testing equipment - Development of solar cell development and evaluation equipment - Development of solar cell performance measurement equipment - Proposal and construction of solar cell performance measurement systems - Development of control software for in-house products - Development of control software for embedded systems of in-house products - Contract software development design - Contract development related to power control (such as power conditioners) * We will propose systems and products tailored to customer requests. Please feel free to contact us. 【Recent Achievements】 - Delivered SCADA system for the Smart System Research Building at the National Institute of Advanced Industrial Science and Technology (AIST) Fukushima Renewable Energy Research Institute - Developed smart inverter automatic testing system (NEDO 2020 fiscal year technology research and development project for discovering and commercializing new energy seeds "Phase C (practical research and development)") - Developed simulated power server (2020 fiscal year renewable energy-related technology verification research support project) - Received "Special Jury Award" and "Encouragement Award" at the 2022 JEMA Electrical Industry Technology Contribution Awards - Received "Excellence Award" and "Encouragement Award" at the 2023 JEMA Electrical Industry Technology Contribution Awards - Received "Excellence Award" at the 2024 JEMA Electrical Industry Technology Contribution Awards
