November 1 (Friday) 10:00 AM - 11:00 AM Announcement of the 6th webinar. "What are the key factors in adopting solar power and battery storage systems?" Registration is now open.

Switching unnecessary (always powered type) for 'always and in case free' - towards a phase-free environment for 'disaster preparedness without preparation' OFGSⓇH series.

The OFGS® (OFF GRID SWITCH BOX) series from Tsuruta Electric is a switchboard/transmission system that integrates a transformer with control and protection, developed to maximize the use of solar battery storage both during normal operation and during power outages. The OFGS®-H series is a constant power supply system designed for hybrid battery systems. Even during power outages or restoration, it allows for seamless power supply and autonomous operation without the need for manual intervention, thanks to the automatic switching mechanism of the dedicated transformer. This system fully utilizes the capabilities of hybrid PCS without the need to switch between grid and off-grid modes, addressing challenges related to installation conditions for corporate renewable energy initiatives such as BCP measures, phase-free operations, and RE100. It enables the construction of a battery storage system that provides clean energy from natural sources (solar power) and off-grid (independent of the power grid) without distinction between normal and emergency situations. By packaging "three-phase transformers" + "Scott transformers (for specific single-phase loads)" + "protection devices" + "control devices" into an 'all-in-one package,' installation and construction time can be significantly reduced.

On November 20, 2025 (Thursday) and December 2, 2025 (Tuesday) from 11:00 to 14:00, our representative, certified public accountant and tax accountant Koichi Yokoyama, will be speaking at a free webinar hosted by Otsuka Shokai. He will explain important points to note regarding the revised Construction Business Act. [Construction Business Act / Public Works Optimization Promotion Act] - Prevention of omissions in the description of construction contracts - Obligation to notify "risk" information before contract signing by the contractor - Mutual exchange of original copies of construction contracts - Digitization of estimates, contracts, and order forms/acceptance letters We are entering an era where contracts must be documented in writing and stored electronically. Paperlogic is fully committed to supporting companies that have begun the transition from paper to digital.
