"SmartSC" is a technology developed by our company to maximize self-consumption of solar power. It is a system that allows companies to use electricity generated from their own solar power installations in factories and stores without selling it to the power company. By consuming the electricity they generate themselves, companies can reduce the amount of electricity they need to purchase from the power company, thereby lowering their electricity costs. We predict the amount of electricity generated based on weather forecast data up to 36 hours in advance and estimate electricity consumption based on actual consumption data. This allows us to determine the surplus or deficit of generated electricity in relation to consumption, and manage the appropriate state of charge (SOC) for the battery storage. [Features] ■ Ability to store excess electricity for use at night or during other times ■ Continued electricity usage during prolonged large-scale power outages ■ Reduction in basic electricity charges ■ Weather forecasts up to 36 hours in advance ■ Efficient battery usage based on predictions *For more details, please refer to the PDF document or feel free to contact us.

"SmartSC" is an optimization control system that maximizes the full potential of batteries through the prediction of surplus power in a self-consumption system that combines solar power generation and storage batteries. By consuming the power stored in advance based on surplus predictions derived from generation and load forecasts, it maximizes "surplus utilization" while maintaining a high charging rate of the batteries. Additionally, it leverages the high charging rate to reduce basic electricity charges through "peak cutting," and maximizes "power supply to critical loads" as a BCP during disasters. "SmartSC" is equipped as a standard technology to maximize these three effects brought by storage batteries. 【Effects】 ■ Maximizes the effects of "surplus utilization," "peak cutting," and "BCP" ■ Generation forecasts up to 36 hours ahead using the Japan Meteorological Agency's "meso model" ■ Load forecasts up to 36 hours ahead based on load and temperature history and temperature predictions ■ Provides profitability simulations *For more details, please refer to the PDF materials or feel free to contact us.

The best solution for long-term power outages is a generator, but there is a delay between the occurrence of the outage and the startup of the generator. The SFT-D series is an uninterruptible power supply (UPS) designed to fill that gap. This device uses its built-in battery to supply power without interruption during an outage while simultaneously starting the generator. After confirming that the generator is operating stably, it switches from battery power to generator power. Additionally, when the power outage is resolved, it synchronizes with the commercial power supply before switching back to it. 【Features】 - It has the ability to absorb noise and surges since it is always powered by the inverter. - The switching time during power outages and restorations is instantaneous and does not affect the load at all. In the event of a device malfunction or overload, it automatically switches to bypass mode without interruption. - After recovering from an overload, it automatically returns to inverter power (auto-return). - The generator uses low-cost diesel fuel. - It operates at low noise levels, minimizing external impact. *The generator is sold separately.

From lithium-ion batteries used in mobile phones and laptops to batteries used in hybrid cars, a wide variety of batteries are utilized. In the development of these battery application devices, obtaining fundamental data such as the durability of the built-in batteries is essential for verifying the reliability of the application products. However, traditionally, building such a system required the preparation of charging and discharging devices (since there are no large-capacity products, power supply and load had to be prepared separately), data loggers, and software to control them, which was difficult in terms of time and cost. Recently, we have developed a new charging and discharging device specifically for battery charging and discharging, along with dedicated data loggers and software. 【Features】 - Compact and high efficiency - Various control modes - Achieves fast response - Interfaces support Ethernet and CAN - Local operation uses a touch panel and jog dial - Custom products can also be manufactured
